There are a lot of friends in the Honda Accord sedan, the engine is F23A1 type, equipped with variable valve timing system (VTEC), after traveling 31,000 kilometers, ABS lamp lights up abnormal, need to use OBD Diagnostic Tool.

Honda Accord sedan ABS system consists of a solenoid valve safety relays, pump relay, wheel speed sensors, hydraulic pressure regulator (pump solenoid valve and a sliding piston assembly), accumulator, pressure switches, ABS lights and ABS computer components.

The car is equipped with self-diagnostic system, remove the right side of the glove box, to find self-diagnosis seat blue 2-hole outlet, using the Launch X431 GDS or Launch X431 V+ Pro3 tool to check. The ignition switch is pulled to the ON position, ABS lights flashing fault code is 10, indicating that non-stop operation of the electric pump the brake fluid. But boot up ABS lights, the pump does not turn. According to the principle and circuit diagram analysis ABS system, the cause of this fault code may be caused by insufficient pressure or pressure switch can not be closed.

Checked for leaks, ABS tank is not short of oil. So to find the pressure switch wire (yellow) to the computer at the office and the hydraulic actuator Ground Test. Ignition lock ON state, ABS lights, start the engine, ABS lamp. ABS pump operation, after the 10s ABS lights, pump stopped. Then the yellow line Ground, ABS lamp goes out, after re-grounding 5s, ABS pump stops, so repeat 1min, ABS lights were never bright. Measured with a multimeter pressure switch grounding line is normal, open the hydraulic actuator on the pressure switch cover, using a flat-blade screwdriver move microswitch direct pressure, measured with a multimeter two terminals blocked, replace micro switch on the same type of ABS, loading retest car, ABS light is off, everything is normal.

Because of the pressure switch on the micro switch is damaged, start the engine, ABS pump operation, produce high pressure brake fluid to the accumulator, solenoid valve, pressure switch, even boost, but at this time the pressure switch can not be closed, Autel MaxiDas DS708 or Autel MaxiDiag Pro MD801 tool detected ABS pump work for a certain period of time, the hydraulic pressure is still not up to the pressure, can not use the ABS system and shut down the ABS pump, ABS lights lit. Replace the same model ABS micro switch, ABS lights go out, everything is normal.

Friends often say, want to buy a used car, but do not know how to choose, do not know what to pay attention, although used car can save a lot of money, but if you buy a lot wrong with the car, not worthwhile. Have this concern is not unexpected, can not just look at the appearance and to decision, you need to use the Auto Diagnostic Tool to check the performance of the car.

Sellers To make cars look more beautiful, will advance to the car beauty and let the car looks clean, almost like new. Care of the first impression, this car certainly will leave a deep impression. Do not know the surface of cooked glamorous car, in fact there are many problems, maybe a car accident. So in the purchase of second-hand car, do not be confused by the appearance of the car.

Buy big brands of cars, that new car prices are too high, wanted to buy a used car, but luxury cars follow-up care is very troublesome, generally small repair shop can not to repair, furthermore the price is also very expensive, as well as maintenance costs, maintenance costs, might be able to buy a nice new car. In fact, more popular models and brands are the best to take care of, where can go where maintenance, cost is also reasonable, they can even use the Launch X431 IV GX4 Master or Launch X431 Diagun III tool maintenance.

Many people buy a used car through a friend, first of all is a friend and not as embarrassed openings at bargain prices, view vehicle formalities are complete, a contract's time to take a closer look, these are designed to ensure their own interests.

Cars are not consumer goods, with more or less a long time there will be some problems, so use Autel MaxiSys MS908 or Xtool PS2 tools check the condition is necessary. Check whether the body has a collision, the chassis is damaged, the exhaust pipe is rusty, as well as the engine, gearbox, water tank is leaking, seepage. The most important is the engine, the engine is the heart of the car, so should pay special attention, in addition to see the engine's appearance is dry, exhaust pipe is sealed, but also to start the car, listen to the sound of the engine is normal.

How to identify under what circumstances need to replace the wiper?
1. From the wiper itself, the symptoms of damage. Identify whether there are cracks, cracks, rust, deformation, adhesion, color and so on; with ears to distinguish wiper when use whether jumping, such as jitter abnormal sound; the use of OBD Diagnostic Tool to check whether the hardening of the rubber, etc..

2. In the process of using see symptoms from the windshield. , look to whether have a slender stripe, is hard to see the outside world, this is because there is foreign body on the wiper or edge frayed, processing method first cleaning the edge part, if you do not eliminate symptoms will need to be replaced.

3. After the rain wiper is wiped, leaving a trail of water, this is because the deformation of the rubber. If the rubber is not in contact with the glass surface, this suggests that the bracket deformation, wiper need replacing.

4. Check the wiper blade. The wiper pull up, finger touch on the cleaned rubber wiper blade, check whether there is damage, but also check whether the rubber blade has good elasticity, if the leaf aging, hardening crack, it should be replaced with new ones.

Check the battery electrolyte level should pay attention to what areas?
Check the electrolyte level, parked his car in a horizontal road, engine, by observing the battery shell on the scale line. Position, if it is difficult to determine the liquid surface of a battery, and with the aid of a lighting to see, can also use the Launch X431 GDS or Launch X431 V Pro tools to check the electrolyte level.

New battery is provided with an indicator, can through the indicator to check the status of the battery. Indicator on the green dots obviously show that the battery in good condition: a green dot blur, shows that lack of electricity: dots become transparent or yellow, indicate the need to replace the battery.

Its different battery indicator is displayed may be different. through Autel MaxiSys Mini MS905 or Autel MaxiScan JP701 tools real time data display, if the battery indicator is blue when normal, insufficient amount of electrolyte is red, when white needs recharging. There's battery level indicator at the square hole below the liquid level is too low, when the indicator of the level below the square hole for liquid level is too low, as it happens and square hole level as the standard, more than at the bottom of the square hole and filled with liquid mouth when too much for the amount of electrolyte.

Before trying to repair the car you have to always wear goggles, when necessary, still need to wear the PPE personal protective equipment, such as latex gloves or closed type shoes. Keep in mind that petrol is highly combustible, and when you are ready to deal with the fuel system to ensure that there is a fire extinguisher and Auto Diagnostic Tool, to prohibit smoking, to ensure that the fire away from the car or fuel tank, must be careful when working.

Steps:
1. To park the car on a solid plane.

2. Reduce pressure fuel system (fuel injection systems operate at very high pressure environment, the need to reduce pressure), follow these steps:
(A). Loosen the valve cover to reduce the fuel system pressure
(B). Remove the fuel pump relay or fuse (according to your owner's manual operation)

3. Start the engine until you run out of the pipeline gas engine stop.

4. To find the position of the fuel filter, which is generally below the engine or the fuel tank. If necessary, you can use the jack to lift the car, and from the fuel filter out of the oil pipeline.

Note: The old car carburetor, the oil pipe is hose with spring. The new injection type engine, the oil pipeline and the clip together, or the quick lock connector, require special Launch X431 PAD or Launch X431 V+ Pro3 tools to remove.

5. Remove the mounting bolts of the fuel filter, fuel filter can be removed then.

6. Compare whether the new fuel filter and removed type is consistent, confirmed after installing a new fuel filter, pay attention to ensure its leading to the engine, can filter retaining bolt installation confirmation.

7. connected to the pipeline and install the fuel pump fuse.

8. Re connecting the battery box, and you can lower the car after it is finished.

9. Start the engine and check for fuel leaks.

Note: Due to the lack of fuel, the engine may not start immediately, but with the fuel pressure increase the engine will start.

10. The actual driving cars, using Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check whether the engine is weak.

A driving of about 68000 km of the audi A6 car. When the vehicle is normally started or driving, EPC light appears on the dashboard. You need to use the OBD Diagnostic Tool Check.

Use 5052 check, the engine fault code 05924, start the machine on the short circuit signal suppressor. As a navigation fault diagnosis, no results. Using the Launch X431 PAD or Launch X431 V Pro tool, it was found that when the clutch pedal is pressed lightly, the EPC lamp is extinguished, and thus can be judged, and the EPC lamp is on the clutch pedal switch. Access to ELSA, that this switch is F194 - for the start of the engine clutch pedal switch, the circuit diagram shows the F194 by J623 control, assuming the internal short-circuit F194, then do not have to set foot clutch pedal, you can start the engine. Results can start the engine. As the vehicle traveling in the engine control unit a direct clutch switch signal, the engine control unit will light the EPC lamp. Solution: replace F194.

This fault can be directly analyzed from the fault code, if you are not familiar with, you can use the Autel MaxiSys Pro MS908P or AUTOBOSS V30 Elite tool to check, the engine is controlled by the engine control unit, the engine control unit to receive the clutch switch signal to control the starting machine, so logic is easy to find fault.

Audi A8 car airbags as a standard configuration. For this system fault repair, need to master the structure of the system, working principle, and the Auto Diagnostic Tool correct test method. Here combined with the specific failure systematically to introduce.

1, Audi A8 airbag system structure and function
Audi A8 uses a multi point electronic sensor type airbag system, mainly composed of the following parts: control unit, side impact sensor, airbag, contact unit and safety belt tensioning device, etc.

Control unit, which includes 1 electronic acceleration receivers (i.e., frontal impact sensor), microprocessor, 1 mechanical acceleration receivers (for insurance), diagnostic systems (with memory), 1 accumulator and 1 crash recorder. The main function of the control unit is to receive the signal of the collision sensor, safety belt switch, monitor the status of the implementation of the system, the final issued instructions to the detonation of the airbag, the engine stopped working, connected to the alarm switch and lights up the fault lamp, and has self check, system monitoring and storage of fault information, crash records and other functions.

2, testing methods and precautions during maintenance
Audi A8 sedans airbag system has self-check function; Every time in the car when the system will detect the introspection; Once the system has a fault is detected, the instrument of red AIR BAG light will be bright. If the indicator light does not shine on when the ignition switch is turned on, or when the light is on, the system is in trouble, the system is in trouble. Fault diagnosis of the system can only be diagnosed by V.A.G1551, A. G1552 V., AS5051 V or other Launch X431 PAD or Launch X431 GDS diagnostic apparatus.

In addition, the system and the Audi car other electronic control systems, by using a dedicated Autel MaxiDas DS708 or Autel Maxidiag Elite MD702 diagnostic instrument that can be queried, troubleshooting part number and system software version of its system, the implementation of the final element, clear DTCs, read data blocks and coding and other functions to the control unit, the system's address code is 15.

No matter what kind of car airbag, it is only as a safety device, and can not put it as an absolute guarantee of adult life. So, in daily driving, we must pay more attention to the safety of driving, be sure to use the safety belt device.

Now more and more people have cars, but very few people understand the car, many owners fear the car suddenly go wrong, but do not know how to use OBD Diagnostic Tool to detect car. Then the car suddenly go wrong before What are the signs? Summed up the car before the failure of eight abnormal symptom.

1, the working conditions mutation
The working condition of car suddenly appear abnormal phenomenon, it is easier to detect fault symptom. For example: engine stalling and start is difficult, can't even start; Engine on the road suddenly drops, driving weakness; The road suddenly brake failure or wandering, or even failure, etc.

2, abnormal sound
Cars appeared abnormal sound in the process of moving, a car failure "alarm", the driver should immediately stop using the Launch X431 PAD or Launch X431 Cresetter tool to check. Especially the chassis, engine, suspension system abnormal sound coming from the most important.

3, exhaust abnormal color
When the engine work, exhaust smoke should be obvious. If you exhaust the other colors appear, it may be the engine abnormal, such as incomplete combustion exhaust was black, oil water blending in tail gas of a white, burning oil exhaust was blue.

4, oil spills
Leakage refers to the phenomenon of oil leakage in the fuel, oil, brake fluid, etc.. It is also obvious symptoms of failure, careful observation can be found. The car was removed after a period of time, there will be a piece of oil on the ground.

5, overheating
Usually it occurs in the engine, transmission, differential and brakes assembly. For example, engine overheating, mostly for the cooling system has a problem, is the lack of coolant or the pump does not work; transmission overheating, mostly due to lack of lubricants; brake overheating, brake shoes, mostly caused not return. The above phenomenon sometimes dashboard warning lights reflected directly, when the driver needs to drive observe.

6, inexplicably increased fuel consumption
Fuel and oil consumption is too high, indicating that the engine fails, we need to check service as soon as possible.

7, strange odor
Cars In operation, if the brake dragging clutch slip fault, will emit a friction plate of burnt; engine overheating, lubricating oil blow-by combustion, it will emit a special smell; a short circuit, grounding there will be a coke burnt smell the wire burned.

8, the appearance of abnormal posture
Cars parked on a flat site, use Autel MaxiScan JP701 or XTOOL VAG401 tool check appearance condition, if any horizontal or vertical skew phenomenon, namely abnormal appearance. Cause is that the frame, body, suspension, tires or other failures, which would cause instability when traveling direction, wandering, weight transfer fault.

Car sunroof is a very common configuration comfort. So the question is, did you use Auto Diagnostic Tool maintenance skylight? Here we come to the maintenance of the skylight and note to do a simple introduction.

One. Skylights use a long time, at its rails, the gap will be deposited in a lot of sand or foreign objects, such as occasional clean-up, will wear the sunroof member. It should be cleaned regularly lubricated around and avoid sand deposition, to extend the service life of the sunroof seals. Generally every six months, to use gauze or cotton dipped in water to wash the sealing tape or slide, rub after a little grease can be applied. Can be used for a fine talc, can prolong the service life of the sealing ring.

Two. Use skylights biggest concern is leaking, proper use and maintenance of skylights can effectively avoid leakage. Before entering the rainy season, in addition to clean up slide, seal gap is the foreign body, but also a harness protector or talcum powder sprayed on the seals and other components.

Three. Before turning on the skylights, should pay attention to whether the roof has obstacles to the operation of the glass panel. Sunroof panel design has isolated the heat and ultraviolet function, please use a soft cloth and cleaning agent cleaning, never sticky or have corrosive cleaning agent, you can also use Launch X431 V+ Pro3 or Launch X431 V Pro tools to detect the sunroof.

Four. On the very bumpy road best not to completely open the sunroof, otherwise may have skylights and slide rail vibration between related parts deformation caused by the too big to even make the motor damage. In addition, rain or cleaning vehicle when it is forbidden to open sunroof.

Skylight is not just a piece of glass so simple, its structure is quite complex, once skylight some failures, using Autel MaxiSys Mini MS905 or Autel Maxidiag Elite MD701 tool maintenance and replacement costs is too high, panoramic sunroof maintenance costs even higher. Therefore, the maintenance of skylights not be ignored.

Some car owners may very strange, the same a car, even for the same car, let others open, fuel consumption fell by half! Why do you have a higher fuel consumption than others?

1, bad habits: rapid acceleration
Personal driving habits have a relatively large impact on gasoline consumption, due to the mechanical design of a variety of styles, you need to run for a period of time will enter a relatively good state. During start-up, hard acceleration, braking and sometimes a good opportunity to reflect performance of the car. Driving this surge will make your fuel consumption, by OBD Diagnostic Tool test data show, it is 2-3 times the normal driving! Best driving speed is preferably maintained at 60-80km / h. And observe the road conditions in advance, it can be done with the throttle control for speed!

2, traffic reasons
This may not have much relationship and driving, but also fuel efficient route choices very important part, sometimes from far away, in the choice of route, try to choose not congested routes, from as short as possible! Only in this way can save more gasoline!

3, trunk mat put too much items
Vehicles carrying too heavy items, will make the fuel consumption is higher than the normal driving fuel consumption of about 2%! It may not seem like a lot, with a long time Many a little make a mickle., so many items, the count is not a small sum of money. So don't put things in the car!

4, pay attention to tire pressure
Some car owners may think that hot summer weather, the tire will Rezhanglengsu, so slightly deflating the tires! Suitable tire pressure for fuel consumption and life of tire is very meaningful! Through the Launch X431 IV GX4 Master or Launch X431 V Pro tool test, as long as there is a tire less hit 40Kpa of gas, the life of the tire is reduced by 10000 kilometers, an increase of 3%! If the tire pressure is reduced by 30%, to 40km/h to calculate the words, the fuel consumption will increase by 5%-10%! Therefore, adjust the tire pressure is more important for fuel-efficient terms!

5, engine technology
When buying a car should be aware that some young owners obsessed with appearance of the car, ignoring the fuel consumption and other factors, recommendations in the car before first practical Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect the car engine, engine technology for fuel-efficient advantage whether performance excellence. This is also very important!

In the morning to open a automobile skylight: release of harmful gases
Car after a period of time of airtight, after Auto Diagnostic Tool detection, air filled with more benzene, formaldehyde and other harmful chemicals. The first thing in the morning on the car, that is, open the sunroof, the use of negative pressure ventilation principle, rapidly clearing the car of harmful gases.

Open sunroof traffic jam: prevent exhaust into the car
When traffic jams, all vehicles are at a standstill, automobile exhaust will inevitably spread in the surrounding air. Then open the sunroof, and close the side, the car's gas will soon be discharged, and then the outside air into the car through the air conditioning filter out large amounts of harmful substances.

After exposure to open sunroof: to quickly lower the temperature inside the vehicle
In the hot summer, the car after sun exposure, the interior temperature becomes higher than the outside, then into the car will be very uncomfortable. After Launch X431 PAD or Launch X431 GDS tool test data show, in order to quickly lower the temperature inside the vehicle, an effective method is to open air-conditioning at the same time open the sunroof, in the heat discharge and air conditioning refrigeration effect after began to emerge, the skylight close again.

High-speed driving to open sunroof: reduce wind noise
When you open the side windows high-speed driving, the owner often be annoying noise and he could feel the strong winds plagued also affect driving safety. If you then open the sunroof, close the side, which can effectively prevent this from happening.

Cold Weather open sunroof: Quickly eliminate car mist
Use skylights defogging defogging is a quick way. Especially in the summer and fall, rain, humidity. Alice ventilation position only need to open the sun roof to the rear, the front windshield can easily eliminate fog, ensure traffic safety, when necessary, require the use of Xtool PS2 or AUTOBOSS V30 Elite tools to detect car performance.

Due to the popularity of cars, so many people will be familiar to car maintenance, but some people are not very understanding, so the use of Auto Diagnostic Tool maintenance vehicles, for some small details do not in place.

Replace automatic gearbox transmission fluid, it is often said that ATF fluid. Most of the cars are highly sophisticated automatic transmission power transmission device, mostly controlled by computer, equipped with a lot of precision components: torque converter, a sun gear, a planetary gear and a complex and fine oil passages and, it is very sensitive to temperature changes and other pollutants. If there is no maintenance, automatic transmission will be difficult and other gear shift. And most of the automatic transmission failure is caused by the transmission fluid pollution.

In the replacement of transmission fluid will generally in hydraulic variable torque converter and transmission cooling pipe is provided with a residual, and the residual amount is more, even with the new then residues were old contamination. In this case the use of automatic transmission cleaning agent completely remove the old fluid, to ensure that no residual old transmission fluid, can completely replace the new transmission fluid.

Under normal circumstances, each driving 50,000 kilometers, it should be connected to the device and the car's power, and the use of the Launch X431 PAD or Launch X431 V+ Pro3 adapter to connect the device and the transmission cooling tube. Start the car and let the engine is running at idle, then add the automatic transmission cleaner, slam the brakes, in order to remove harmful substances, and one by one, replace all gear of the automatic transmission, and finally with the help of automatic transmission oil equipment comprehensive replacement.

If you want an automatic transmission protective agent is added, it is preferably added in the proportion of 5% of this, If it is used for a long time, then it is best to add some stop leakage, to prevent the aging of transmission seals can also achieve the purpose of preventing leakage.

So, for the transmission fluid is a small thing, which can be a lot of things to note, the owner replaced when we must pay more attention to, and need to use professional Autel Maxidiag Elite MD701 or XTOOL VAG401 tools to detect car.

Rainy day driving, the vehicle sideslip possibility increases, in addition to good driving habits and skills, but also the brake and the state of the tire good is also the key to safe driving. Automobile brake system is the most dual vacuum assisted hydraulic brake. Brake fluid transfer braking force which has strong water absorption. If water into the brake fluid in the braking process, the high temperature friction will produce water vapor. The gas is compressible, the brake fluid is compressed, it will cause brake failure or even failure, so after a rainy day, the need to use the OBD Diagnostic Tool to check vehicle braking systems.

Solution: Some brake fluid absorption water more serious vehicle, in the brake fluid oil on the cover can see water droplets. So in the maintenance must use the Launch X431 PAD or Launch X431 V Pro tool to check the brake fluid, to ensure the life safety of occupants. Once found the car brake fluid suction serious, should be sent to the professional repair shop in addition to water.

Also, before the arrival of the rainy season, if the vehicle tire wear, tire wear, must be replaced. someone to reduce tire pressure every rainy season, the purpose is to make the friction between tire and ground area increases, thus increase the adhesion, actually just the opposite, it is easier to cause the tire skid, keep the normal tire pressure is very important, regular use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect automobile tire pressure.

Car maintenance cycle is every car person should understand knowledge, car maintenance cycle table covers the oil, four filters, consumables. Recently, many friends some questions related aspects of vehicle maintenance and periodic table of advice, consultation with these questions today some automobile maintenance industry experts regard and the knowledge learned are summarized as follows:

First, the oil and oil filter
Cycle: every six months to replace (or 5000 kilometers), the replacement of some way to go on the freeway, oil choose yellow "shell" brand.

Second, the air filter and spark plugs
The cleaning cycle: once every half a year, changed every 30000 km, usually platinum spark plugs can be durable 50,000 km.

Third, the fuel filter
Frequency: Annually replaced once (or 10,000 kilometers), can be determined according to the quality of gasoline.

Four, brake fluid
Cycle: every two years to replace, in order to avoid brake fluid absorbs moisture and corrosion of components.

Five, coolant
Period: check once half a year, to increase the coolant, and check the concentration, the need to add distilled water, it is forbidden to add water, otherwise the corrosion of water tank and components, liquid level height can't more than a full, water thermometer temperature higher than 90 degrees said must increase refrigerating fluid in a timely manner.

Sixth, the camshaft drive mechanism and the toothed belt tensioner
Cycle: changed every 80,000 km.

Seven, throttle
Cycle: cleaned once every six months (or underpowered station speed instability when cleaning). 1 year or 20,000 km Replace air filter once! Air filter replacement cycle for 5000-10000 km, gas filter can be 15000-20000 replacement.

Hot summer temperatures, the hot sun road car to withstand the ordeal, the engine temperature is too high is summer cars need to pay special attention to matters, prevent the engine temperature is too high to pay attention to the following four bogey.

A bogey: boil immediately when opening the lid, add water
Radiator in the inland waters after boiling, internal pressure to a certain extent, if at this point immediately open the radiator filler, from hot water can, causing burns. The right thing to do is to find the tank water boiled, immediately opened the hood to increase air flow, when the water temperature drop is no longer a boil, then use a wet towel to do hand pad, radiator water cover unscrewed a first block and release of water vapor, a moment is opened entirely. To avoid water mouth above will face at the same time, to prevent scalding hot water overflowing face.

Second, avoid: boil after flameout immediately
Some drivers found after boiling, thought is immediately shut down. Want to know: Engine why boil is due to high temperature of inner water jacket is jacketed tank, wall, cylinder head temperature too high. At this time if the flameout, parts are in expansion in the state, with the gap is very small, after the shutdown will result in some soft metal off, and some will even cause sticking cylinder. So that after boiling, don't immediately turn off, should remain idle.

Three bogey: when the engine temperature is too high, pour cold water poured engine
Car launch forget to add cooling water temperature has been found to be too high, so he to the engine block, cylinder head and poured cold water to cool. Little do they know the consequences are serious, may cause the engine block because the quenching burst, causing irreparable consequences. Engine temperature will overshoot bad head gasket, burn Bush, machinery accidents; temperature is too high, causing the intake air drops, power is reduced; the tank boil, boiling coolant evaporation overflow; Launch X431 CResetter II or Launch Creader VII tool test showed that the engine will meet the various components gap decreases, increased wear and reduce engine life.

Four bogey: bogey water tire cooling when the temperature is too high
When the tire temperature is high, are due to the installation is not accurate, the speed is too fast and other reasons, but also the hot natural climate caused by. If in tire temperature is high throw cold water is bound to cause fetal internal structure due to sudden changes, resulting in the deformation matrix inside each ply between a, cause early damage to the tire, even the cord stripping. In addition, should also pay attention to the tire pressure and temperature, otherwise easy to explode accident. Once burst, light affects the speed; that will have a serious accident. During the rest of the journey, check the tire temperature and pressure in time. If it is found that the tire temperature, tire pressure is too high, can not take deflation and pour cold water on the way, should choose the shade, parking, the tire temperature, pressure drop of natural; such as wading, should be tire temperature decreasing after wading to prevent tire early damage.

Hot summer temperatures, in order to prevent the engine temperature is too high, it should pay attention to the following points: 1 plus sufficient cooling water; 2. Autel MaxiSys Mini MS905 or Autel MaxiDas DS708 tool to check the thermostat is normal. 3. driving in the instructions and pay attention to water temperature readings, requires no more than 95 ℃. 4. In exceptional circumstances, in order to strengthen the cooling air convection, can lift the hood to facilitate ventilation.

Cars over some speed humps, the normal speed through the speed humps, through OBD Diagnostic Tool detection show that it will damage to the vehicle, and ride comfort have influence, encountered deceleration zone how to through?

The effect of speed humps just as its name implies is to make the vehicle to slow down, even if the vehicle is not loose throttle or brakes, the vehicle up and down motion of the reason will be because certain rate weakened. Of course, the main role of the deceleration zone or let the driver subconsciously reduce vehicle speed by this section, the initiative allows the driver to pay attention to the road conditions ahead, generally in front of the school may be crossing or continue downhill.

1. Before experiencing the deceleration zone, the first driver's consciousness is closing the throttle and tap the brakes, and pay attention to road conditions ahead, and through the rear of the rearview mirror to observe road traffic conditions, if trailing behind the vehicles more, close the throttle to reduce speed must not to slam on the brakes. It is easy to cause behind the vehicle rear end collision, you can use Launch X431 GDS or Launch X431 IV GX4 Master tool detection of brake system.

2. For automatic transmission vehicles, as well as from the deceleration zone after a short distance, according to the vehicle damping performance and road driving conditions, the vehicle speed control at 30Km / h or less, but not too low. Although the lower rate turbulence weaker sense, but it will affect the overall rate of road traffic. Vehicle speed control to a certain speed, the rear wheels begin to spin down when the band can throttle speed.

3. For manual transmission car with a manual transmission car is relatively complicated. Before entering the deceleration zone when some began to collect the oil from the deceleration and observed the traffic situation around the vehicle, and based on the vehicle speed sequential shift into low, generally 1, 2 block can be relatively stable through the deceleration zone.

In the vehicle rate below 30Km/h or lower through the deceleration zone, according to the Autel MaxiSys MS908 or Autel Maxidiag Elite MD701 detection. To a file through the deceleration zone, light step on the clutch to do linkage and throttle idle speed, the rear wheel through deceleration zone, observe the road in front, slowly lift the clutch and lightly on the accelerator, according to the speed or engine speed a step on the clutch shift into high gear. At last, the car speeds of up to normal driving state.

Regularly using the Auto Diagnostic Tool check the oil level, oil level is too high will not only increase the engine running resistance, resulting in unnecessary power loss, but also cause oil leakage; liquid level is too low, due to poor lubrication and damage to the engine, so the engine oil level is too low should check the engine without oil leakage and abnormal oil consumption; start the engine before switching on the ignition, the oil level indicator and the oil pressure indicator lights and start the engine should be extinguished.

Use appropriate viscosity of oil, the oil viscosity is too low, the oil film is easy to damage and produce parts sticking phenomenon; Viscosity is too high, it will produce parts of mobile added resistance in engine starting difficulty, increase power loss. You can use a Launch X431 V+ Pro3 or Launch X431 Diagun III tools to check the working performance of engine.

1) According to the climate use of oil. When the ambient temperature is low, the use of small viscosity of the oil, easy to start the engine. When the ambient temperature is high, the high viscosity oil is used to keep the oil film of the movement;

2) According to the condition selection of oil, good condition of the engine, with a smaller gap, can use low viscosity oil, the poor condition of the engine, with the gap is very big, can choose high viscosity oil;

3) The diesel engine has a higher combustion pressure, plus generate sulfurous acid diluted in oil after the sulfur content of diesel combustion, and therefore should be used to neutralize the diesel engine and diesel engine oil sulfite.

Regular replacement of engine oil, it is best not to add oil, if long-term add oil, will make the accumulate inside the engine oil coke, blocking the oil filter, resulting in engine moving parts are not lubricated severely damaged engine parts.

For automotive engine lubrication system, as long as do regular use Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS601 tool to check the engine, not only can extend the life of the engine, it can also reduce unnecessary economic losses.

Engine oil sump, because it is exposed to air and heat, easy oxidation by gradually. As the acid in oil, gelatin, iron filings, asphaltene increased slowly, grows a black, the color of the oil viscosity will gradually decline, at the same time performance, and the provisions of the new oil oil change period must be replaced. But sometimes use Auto Diagnostic Tool inspection found, shortly after oil change, oil and quickly deteriorate, color change from blue to yellow, or black before they suddenly became grey, lost the original technical performance.

(1) the oil infiltrated water
The oil has water, will lead to the sludge formation, so that deterioration of oil contamination, this antioxidant additives and dispersion performance weakened, promote the bubble formation, so that the oil into the emulsion, destroy the oil film. Experiments show that, when the water reaches 1%, the wear of machine parts will speed up 2.5 times.

(2) the crankcase ventilation is poor, poor oil radiator
Engine work, there will be some burning gas channeling into the crankcase, if the piston ring serious damage, this phenomenon will be more serious, crankcase pressure will therefore rise, if the pressure is higher than the outside atmospheric pressure, to the piston moves to bring a certain amount of resistance, resulting in oil by the oil bottom shell and the cylinder body junction leakage outwards. In addition, the leak into the crankcase gas containing sulfur dioxide, will promote the rapid deterioration of oil. For this purpose, it is necessary to make the air pressure in the crankcase and the outside air pressure. Some diesel engine on the ad hoc, the purpose is to make the inner and outer pressure of the crankcase is balanced, you can use the Launch X431 GDS or Launch X431 V Pro tool to detect the pressure of the crankcase.

(3) improper maintenance
In cleaning crankcase, if oil filter or the radiator cleaning is not complete or leakage installed gaskets for oil filter, diesel engine after adding new oil, even if only for a few hours, become dark and dirty oil.

(4) Oil grades improper use
According to the grades of standards, the gasoline engine and diesel engine oil viscosity of each into four grades, where with W word oil is oil for winter, the grade is high, higher viscosity index, all marked with SAE15W-40 grades of oil, is in winter and summer can be used oil, foreign called composite oil and the said oil thickening. Therefore, engine oil must be used to Autel MaxiSys MS908 or Autel MaxiSys Mini MS905 tool inspect its quality and viscosity of the two aspects of the requirements, namely oil grade (API) and oil viscosity grades (SAE); in the selection, only to high grade oil instead of low oil level, otherwise easy to early deterioration of machine oil.

Intercooler and radiator fit together, installed in the front of the engine,draw fans and cars driving through surface air cooled intercooler, if the cooling bad will lead to lack of engine power, fuel consumption increase. Therefore, we should regularly use OBD Diagnostic Tool check intercooler and maintenance, main content is:

1, external cleaning
Due to cooler mounted in the front, intercooler radiator channel is often leaves, sludge such as congestion, make the cold heat up, so there should be conducted on a regular basis to clean.

Cleaning method is not too high pressure water gun to the vertical plane at an angle in the cold, top-down or bottom-up slow rinse, but not oblique thrust to prevent damage to the cooler.

2, interior cleaning, checking
Intercooler internal piping often with sludge, gum and other dirt, not only narrows the air flow path, and reduce cooling heat exchange capacity, therefore, you must also use Launch X431 IV GX4 Master or Launch X431 PAD tool maintenance and cleaning. Usually every year or engine maintenance and repair welding tank at the same time, to deal with the cleaning and inspection of internal cold.

Cleaning method: containing 2% sodium carbonate aqueous solution (temperature should be in 70 - 80 DEG C) added to the intercooler and refill and wait for 15 minutes, fancy cooler has no leakage of water. If leakage, to deal with the dismantling and repair welding ; if there is no water leakage, rocking back and forth, repeated several times, poured lotion, again filled with clean containing 2% sodium carbonate to wash solution, until it is clean now, together with clean water (80 - 90 DEG C) cleaning, until the release of clean water so far.

Such as cold machine external on oil, also can use alkaline cleaning, the method is: put the oil soaked in lye, clean with brush, until clean.

After cleaning with compressed air inside the water cooler or dry natural dry, or when installing the cooler is not connected to the intercooler pipe connected to the engine, start the engine until the intercooler outlet without water When, connect the engine intake manifold. If it is found within the intercooler core is extremely dirty, should be used Xtool PS2 or Autoboss V30 SPX tools carefully check air filter and intake pipeline where various loopholes, and troubleshooting.

Spark plug is one of the main components in the ignition system of a car engine. On all gasoline engines have spark plugs. High-speed petrol engine is also equipped with two spark plugs per cylinder. Spark plug is the ignition coil to generate a high voltage electricity into the engine cylinder and between the electrodes of the spark plug gap spark to ignite the air / fuel mixture, so the spark plug is a very important component, the need for regular use of OBD Diagnostic Tool check spark plug operating state.

If you can not confirm the type of spark plug, recommended reference to the factory maintenance manual. Different models of automobile manufacturers specified maintenance intervals are not identical. Maintenance manual for a general basis, the different usage of different driving habits will affect the state of the spark plug.

If it is found in the cool car status car more difficult to start, with a clear sense of frustration while driving, idling jitter, or the engine acceleration performance can decrease, should be timely using Launch X431 Creader VIII or Launch X431 Cresetter tool check the spark plugs. Because the vehicle once appear, the above several kinds of performance, is likely to be due to aging caused by the spark plug.

The common phenomenon of spark plug: carbon or precipitate; electrode melting or corrosion.

Once that happens, it will cause the car to a cold start is more difficult, with a clear sense of frustration while driving, idling jitter, the phenomenon of self-extinction is frequently occurred, the engine speed performance is reduced, the power shortage and fuel consumption are increased.

When replacing the spark plugs must comply with the provisions of torque. Do not install too tight, too loose but can not be installed, otherwise it will cause the engine not working properly, recommend the use of special Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools installation.

The engine is the heart of the vehicle must be protected. The quality of the oil not only can reduce engine wear, increase engine efficiency, by OBD Diagnostic Tool to detect, but also to save fuel consumption, extended drain intervals and help keep the engine clean and prolong engine life, long-term performance of the engine as new.

There are three cases car burning oil
1, the valve seal leakage at the oil, because the poor quality of the valve seal, or the engine temperature is high, or exhaust vent is blocked leading to the greater impact of the valve seal.

2, Crankshaft ventilation mechanism can not be filtered out of the oil, leading to oil is sucked into the inlet, the only use Launch X431 V Pro or Launch X431 Diagun III tools to detect oil filter components, to eliminate failures or improve efficiency.

3, From piston engine oil leakage, for this performance, throttle only exhaust side have the carbon deposition, but the most damage, the main reason is lack of the inferior quality or process precision of piston and piston ring, under the turbine, the piston ring of gas oil energy is larger, the destructive force of the piston ring of piston is bigger, more heavy oil burning.

Overall, the engine burning oil to avoid is the use of qualified and suitable lubricants, and changed regularly. But note that the different cars engine design, therefore, in view of the model in different countries, the cost of repair and repair after the effect of the difference is very big. Universal significance and practical advice is to use good oil and regularly replaced.

Some burning oil was designed to be, this is actually the main part of the current owners complaints: obviously the vehicle does not have any fault, but the oil consumption is particularly large. So for the engine easy to have a fever, usually to use the Autel MaxiDiag Elite MD802 or Autel MaxiSys Mini MS905 tool to check the work condition, the regular check the oil consumption is normal, etc..
