A, use and maintenance
zfak6-90 and zfs6-90 type gearbox is of conventional structural gearbox, and is therefore generally the same gearbox, in use, should pay attention to two issues, a car is driving is prohibited in the engine flameout neutral glide. This is due to the type used in automotive hydraulic power steering system and braking system, once the driving engine flameout, power steering immediately failure, in case of emergency prone to heavy steering caused the accident. You can use the OBD Diagnostic Tool to check the gearbox working state. The engine is stalled and the air compressor is not working, such easy to cause failure of brake failure.

On the other hand, from the gearbox working angle, the car engine flameout and gearbox put it in neutral condition of high-speed planing, as the engine flameout, gearbox a shaft stop rotation, countershaft also stops rotating and the second shaft gear all cease to spin, and the second shaft is in driving sliding car driven by high-speed rotation. Due to the gearbox all the gears are in a resting state, splash lubrication can not be generated, such a biaxial within each gear shaft hole needle roller bearing is not enough lubrication and burning loss soon.

Similarly, when the car engine failure was not working properly, the car must be hauled driving, drag distances over 100 meters, must be drive shaft and the driving axle connecting flange apart, the rope bundle of drive shaft on the beam of the automobile, drive axle and drive axle disengaged, drag speed shall not be more than 60 km / hour. Otherwise, also easy to cause biaxial needle roller bearing damage. You can use the Launch X431 IV GX4 Master or Launch X431 V Pro tool to check whether the car engine has a problem.

During the maintenance should be careful to check the level of gear oil. Transmission gear oil that is not the lack of nor Cadogan. Lack of oil caused by early wear even burning fault, oil too much prone to gearbox overheating. In a gas plug on the side of the gearbox, the oil level when the car park in a horizontal position should be in the height of the plug position. There is a drain at the bottom of the gearbox plug. New car during 2000 ~ 2500 km, the first force to maintain the new oil transmission gear oil should be replaced. Oil change the best operating mode in a hot car. Must according to the actual conditions and according to the provisions of the oil gap period.

B, gearbox oil
Gearbox lubrication using gear oil. ZF type gearbox use the international standard aplgl - 4 grade, viscosity grade sae85w / 90 indicator of gear oil. You can use the Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tool to check the gearbox lubrication working state.

Market authorities released test report notes that only qualified additives can reduce fuel consumption, as well as increased power, maintenance engine, remove carbon deposits and other effects. In addition, The analysis of Auto Diagnostic Tool monitoring data shows that, after using the correct fuel additives, in the automobile exhaust hydrocarbon fell by 26.6%, a 19.7% drop in carbon monoxide.

Select the high quality additive, not only can serve to reduce fuel consumption, as well as maintenance of the engine, remove carbon, environmental protection and other effects. More importantly, it is the engine maintenance measures, can prolong the engine's service life. And the use of inferior additives. Black smoke from the rear of the car.

Additives by cleaning the carburetor or fuel injectors dredge, improve fuel flow to reduce fuel waste; and wherein the accelerant for a class of fuel additives are directly involved in the physical and chemical reactions in the cylinder in the engine can be effectively improved engine efficiency. So the fuel additives can still play a role fuel-efficient.

Fuel additives for gasoline and diesel fuel into two additives. Gasoline additive main component is an organic compound with cleaning, dispersion, emulsion, antioxidant, anti-corrosion, anti rust, lubrication, combustion, cleaning function. Not volatile, non-flammable, does not form secondary pollutants, storage safe.

Additives contained in the purification, has been adhered to in other parts of the heating surface grease, gum and carbon deposits in the combustion chamber of the role of pine, making it easy to be in the air in "clear", and after combustion exhaust. Activated molecules such additives added to the oil dispersant that would allow rapid diffusion of small molecules directly attack the oil molecules in the long chain carbon bond, causing complete combustion, improved engine power, fuel consumption is reduced. You can use the Launch X431 Creader VII+ or Launch X431 CResetter II tool to check the engine operating status.

Fuel additive also has many effects, such as:
First, remove carbon deposits, clean the fuel system
Second, enhance the performance of engine power
Third, to improve atomization, save fuel
Fourth, corrosion, rust, lubrication, protection engine
Fifth, reduce noise and wear and extend engine life
Sixth, the elimination of black smoke and reduce emissions

When you purchase fuel additives, to fully understand the composition and effectiveness of additives, buy some products with well-known and well preserve consumer certificate and service bills. Some products contain graphite, Teflon resin particles, fluoride, etc., likely to cause precipitation inside the engine, affect vehicle performance, try not to buy products containing these ingredients. You can regularly used Autel MaxiSys Pro MS908P or Autel MaxiDiag Elite MD802 tools to detect the vehicle performance.

The importance of the brake fluid for driver is indisputable, so, what are the features of best brake fluid, in the choose and buy should pay attention to what issues?

1, Low temperature fluidity is very good, which is particularly evident for cold areas. Using high quality brake fluid in cold as sensitive and reliable braking. The use of inferior brake fluid temperature performance is poor, high freezing point, below -20 ℃ temperatures will have solidified phenomenon, significantly affect the safety of driving.

2. Long-term use of non precipitate, Brake fluid in high temperature condition of long-term use, quality instability will produce thermal decomposition, produce a precipitate, also affect braking performance, Launch X431 Cresetter or Launch Creader V+ tools can help you to check the performance of automotive brake.

3, The brake system of various metal good antirust property. General brake fluid corrosion resistance is stronger, but high quality brake fluid for all kinds of metal corrosion greatly reduce anti-rust, can prolong the life of the brake pump, if add the inferior brake fluid will soon a corrosive action on metals, cause a harm to driving.

4, For a variety of rubber is not corrosion. High quality brake fluid after use cup serious expansion deformation phenomenon will not occur. The use of inferior brake fluid, cups easily expanded and deformed, causing the vehicle oil spills, when the brakes flip, causing the accident. Standard brake fluid in the expansion coefficient is generally 0.1% to 5% .

5, the boiling point the higher the better, lower evaporation. Boiling point of not less than 205 DEG C, when automobile run for a long period of time and in high speed or downhill, and the temperature will be up to the number of brake fluid, brake fluid temperature of the brake shoe temperature increased, if the boiling point of the brake fluid is not high enough, the brake fluid vaporizing, bubble, stepped on the brake is weak that could not be immediately reached to brake, it can not guarantee that traffic safety, in order to ensure your safety, in order to protect your driving safety, please use the timing Autel MaxiScan JP701 or Autel MaxiDiag FR704 tool to check car system performance.

ABS is the installation of the modern car regular device, its function is becoming more and more attention. Because of the ABS system is more complicated than conventional braking system, you can use the Auto Diagnostic Tool to check the ABS system routine performance, therefore when choosing, replacement and supplement the brake fluid should pay special attention to:

The brake fluid correct selection:
1, in the ABS system, there is more rubber seals and rubber hoses, this requires the owner in the use of the brake fluid can't have strong swelling effects on rubber seals.

2, in the ABS system, there are more and more sophisticated metal parts and therefore requires the choice of brake fluid has good corrosion resistance, so as to avoid metal parts from corrosion.

3, in the ABS system, there is a longer, more complicated pipeline, therefore, requires the choice of brake fluid has a high boiling point, in order to avoid the brake fluid vaporize that braking system to produce air resistance, you can use Launch X431 CResetter II or Launch X431 Diagun III tool to check the brake system is working properly.

4, in the ABS system, the brake fluid through repeated pressure increase and decrease the circulation, therefore, the work of the brake fluid temperature and pressure is higher than conventional braking system of brake fluid, which requires the brake fluid has better oxidation resistance, in order to avoid brake fluid in formation colloid, sediment and corrosive substances.

5, the ABS system, brake fluid pathway is longer and more tortuous, resulting in brake fluid in flow process by the greater resistance; in addition, in the ABS system, moving parts more, more sophisticated, these moving parts of lubrication requirements higher. Therefore, ABS system, the choice of brake fluid must possess proper viscosity.

According to the above characteristics, ABS systems generally use brake fluid DOT4, Although DOT5 brake fluid has a higher boiling point, but because DOT5 is a silicon brake fluid, will strong damage to the rubber parts. Therefore, In the ABS system, generally do not use the brake fluid DOT5.

However, due to DOT3 and DOT4 brake fluid is alcohol-based, with strong moisture absorption, with the use of extension of time in which the water content will increase. When the brake fluid contains more moisture, will make dynamic pressure regulation means precision parts corrosion occurs, in cold weather conditions, but also the viscosity of the brake fluid increases, affecting the flow of the brake fluid in the brake system, the brake becomes slow, resulting in system moving distance is extended.

In addition, the brake fluid in the water will have a very significant impact on the boiling point of the brake fluid, gas resistance. DOT3 and DOT4 brake fluid usually after 12 months of use after which the moisture content of 2%, after after 18 months of use, where the moisture content of up to 3%, you can use the Autel Maxidiag Elite MD703 or Autel MaxiDiag FR704 tool to check the brake fluid water content, therefore, suggest you every 12 months to replace a brake fluid.

Function one, lubrication. Fuel additives replacing lead to lubricate the upper part of the engine block, the engine is smooth, not dry, improved power, lower fuel consumption. If you want to know more information, you can use the OBD Diagnostic Tool to check.

Function two, full combustion. When burned, small water microemulsion particle effect at high temperatures swept into the steam generation "micro-explosion" so that the combustion flame propagation is more uniform and delicate, so that the gas atomization is improved, so as to achieve complete combustion.

Function three, antioxidant. Fuel additive antioxidant ingredients can inhibit from fuel components in unstable components and a little olefin diene in the environment under the effect of temperature and air oxidation condensation formation of glial process, avoid the metal surface oxidation of automobile engine, to ensure the normal work of the engine. You can use the Launch X431 Creader VIII or Launch Creader VII tool to test the performance of the engine.

Function four, rust protection . Fuel in the storage and use process, there will be water, can cause rust, oil system for vehicle fuel additives can prevent the rust of pipelines and oil system.

Function five, anti-corrosion. Fuel to meet in the process of transportation, storage, use water caused by the oil emulsion, the oil-water boundary and form slag emulsion cream, cause the clogging in filter, and oil emulsification easy to moisture into the air intake system and combustion chamber corrosion and impact the normal operation of the engine, and composition of demulsification can prevent corrosion and affect the normal operation of the engine.

Function six, clean. Fuel additives contain pollutants, it has been adhered to in other parts of the heating surface grease, gum and carbon deposits in the combustion chamber of the role of pine, making it easy to be in the air in "clear", and after combustion exhaust. Carburetor vehicle hydraulic system, EFI car nozzle, intake valve has the function of keeping clean, using Autel MaxiTPMS TS401 or Autel AutoLink AL609 tool reads the carburetor real-time data.

The oil filter is used to filter the oil dust, metal particles, sediments and suspended particles and other impurities, reduce impurities wear and tear on parts and protect the engine and other equipment. The quality of the oil filter is we have to consider, how to use the Auto Diagnostic Tool to identify oil filter, choice genuine oil filter is our common concern.

Fakes: Filter surface print is not clear or fuzzy, print the paint on the surface of inferior, thin. No bypass valve, once the filter clogging, the engine will not get enough lubrication oil. After flameout did not inhibit the oil return function, cold start of the engine wear will be greater. The gasket sealing material, high temperature and high pressure may cause oil leakage, and even cause a fire. The filter material, to a predetermined filtering effect. Metal oil net coarsely, difficult to guarantee the oil amount of energetic.

Hazard: The counterfeit oil filter pump not only affect the normal lubrication of the engine, and because of shoddy, the interface of the main oil may have Mifengbuyan conditions, resulting in a binding machine oil filter and cylinder face jump out, the result will cause oil leakage, poor engine cooling failure. You can use the Launch X431 V Pro or Launch X431 GDS tool to check these failures.

Genuine: filter surface factory standard font printed clearly, printing paint with good texture, pure white. With internal bypass valve, ensure that any state has a sufficient amount of oil supply. Inhibition of reflux design complex, ensure the filter has the next time you start to oil, reduce the wear of the cold start (all are factory filter this bag is equipped with protection function). Before leaving the factory, a lubricating grease at the interface, the sealing gasket material, rubber material according to the rules. The filter oil specially developed, moderate density, ensure the filter oil filter core. The metal in the form of standard oil through the network, to ensure the oil throughput.

Oil filter is the most commonly used cars consumables, thousands of kilometers will be replaced together with oil. Although this inexpensive small parts, but in the course of normal operation of the engine, but plays an important role. If it's out the problem will make fuel consumption increase, increased engine wear and tear; Severe then let the engine scrapped, So, you need to regularly use Autel MaxiSys Pro MS908P or Autel MaxiTPMS TS601 tool to check the car's performance.

Carbon deposition is spark discharge machining a manifestation of abnormal, therefore, should try to reduce vehicle carbon deposition by some Auto Diagnostic Tool.

First, Don't long time idle running.
Long idling time, the engine reaches normal temperature time becomes longer, the gasoline is injected into the valve back after the evaporation speed is slow, carbon also arises. At the same time often idling speed, air flow into the engine also small, so flushing carbon deposition action becomes very weak, will promote the accumulation of carbon deposition. You can use the Launch X431 GDS 3G or Launch X431 Diagun III tool to detection of carbon deposition.

Second, high-speed running, try to improve my hand car shift speed.
Run high-speed purpose is use air flow on the inlet to prevent carbon deposition. In addition, to improve the speed of the shift also run a high speed have the same role, in the original 2000 speed when shifting into 2500 conversion, not only can effectively prevent coke formation, it can also increase the power of the car, but also to avoid the change burst speed is too low to bring vibration block, protect the engine.

Third, pay attention to turn off car.
For cars fitted with a turbocharger, don't stop immediately after high speed or climbing, in idle running 10 minutes and then stop, because the car is equipped with a turbocharger which carbon formation rate than the average naturally aspirated car several times faster, you can use Autel MaxiDiag Elite MD802 or Autel Maxidiag Elite MD703 tools to detect the car's performance.

The operating condition of the vehicle can be judged by the viewing light on the dashboard, you can use the OBD Diagnostic Tool to detect the car's performance, the following is the meaning of several kinds of led display.

First, the dashboard oil lamp is lit, there are two possibilities, one for oil is insufficient, the engine can not be completely oil lubrication, and normal circumstances oil will not be a large number of consumption, so it is possible that the engine oil leakage. The second reason is the insufficient pressure oil pump. Should stop at this time, in order to avoid the vehicle without oil lubrication under the condition of going to cause engine damage.

Second, when the water level of light on the dashboard, due to the water in the tank will not reduce, should be cooling system problems, there are two possibilities, one is the system somewhere at the leaking, two is too high temperature of the cooling system pressure will exclude water, if the water tank Water Leakage, can be the first to use water in the auxiliary water tank then, try to drive to a nearby garage, please mechanic processing. The position of the water tank and the vehicle side is not the same, recommended that owners use the Launch X431 GDS or Launch X431 Diagun III tool testing, engine working temperature is extremely high, do not easily open the tank cover, so as to avoid the damage caused by the vapor instantly emerge, and don't make the engine running, causing serious injury.

If the water temperature light but not the above situations, it means that the heat generated by the cooling fan problem, we must immediately stop driving, or a sudden rise in temperature, pressure, coolant change stool will become a high-pressure steam leak also cause the engine cylinder head deformation or to make cylinder head gasket is damaged, it needs one to two days repair time.

When the brake oil lights may be brake system leakage, or is excessive brake pads wear, it is best to stop driving, or because the brakes ineffective and dangerous. Additionally ABS lights up when there is no anti-skid brake system, but there is still brake function, the plant maintenance is inevitable approach. Important corollary is regular maintenance every 5000km to 10000km regular maintenance, or use Autel MaxiSys Pro MS908P or Autel MaxiDas DS708 tools to detect car, you can discover car problems before the accident, it will be resolved.

Air filters, oil filters and fuel filter is what we call the car "three filter", their role is filtered into any liquid and gas inside the car engine, the protective effects of engine, while it can also improve the efficiency of the engine, you can use the OBD Diagnostic Tool to detect engine efficiency. Now, it says the main air filter and oil filter replacement and maintenance points.

Air Filter
The main action of the air filter is used to filter impurities in the air, provide clean gas engine, in this process, impurities in the air are adsorbed on the surface of the air filter reach a certain mileage, it will form a black look, this time the filter effect has been very poor, and must be replaced in time, you need Launch X431 IV GX4 Master or Launch X431 Diagun III tools.

In addition, when you find the car underpowered and engine sounds abnormal sound, cost of oil, air filter should be replaced, if the cars used dirty air filter, the engine will enter the gas shortage, so that the fuel combustion completely, causing the engine work instability, power down, increasing fuel consumption occurs, you can use the Launch Diagnostic Tool to detect. Therefore, the car must be kept clean air filter.

Oil Filter
The internal combustion engine use, dust, metal wear, clean carbon and other mechanical impurities will continue to mix the oil, while the combustion air and exhaust gas oxidation of the oil on oil will also gradually produce gum. After using to a certain time, use Autel Maxidiag Elite MD701 or Autel MaxiDiag Elite MD802 tools to detect, machine filter surface will be attached to a lot of dirt, if from time to time to replace the oil filter there will be blockage consequences.

Air conditioning start after the main noise is the working compressor noise, it does not belong to a malfunction. Because the operation of the compressor is intermittent, not always in working condition, when it will start again Loud noise at work, the majority of cases are failures blower control module, the use of Auto Diagnostic Tool checks out, the need for timely replacement the new accessories.

Summer fast approaching, air conditioning has become the owner of the car entered the car primary action. However, while owners enjoy the cool, often feel malaise, these symptoms are typical of the car, "Air conditioning disease." The need for timely use Launch X431 V+ Pro3 tool or Launch X431 V Pro to check, to prevent the effects of health.

The horn is a frequent use of the device while driving, if the speaker fails, it will be very difficult when driving. Sometimes honked the horn, the sound is very hoarse, and even a little voice at all. We need to use the Auto Diagnostic Tool timely detection, we take a look at how the horn works. When the horn button is pressed, the battery current will flow through the loop on the horn relay solenoid, solenoid relay attract dynamic contact switch is closed, current will flow to the speaker place. Electromagnet current work inside the horn, so that the diaphragm vibration sound.

According to the author's experience, many faults related to the speaker, problems arise fault is often the horn itself . Especially flawed speaker installation location of some design, when it rains very easy make the speaker wet in the rain, causing damage to the speaker. When the speaker does not ring, common failure parts are nothing more than 3 points, that horn itself, horn switch contacts and horn line, when a fault occurs can be used Launch X431 GDS or Launch X431 IV GX4 tool to check the following steps:

(1) sometimes does not ring. Press horn switch, if the horn is sometimes loud, sometimes does not ring, mostly inside the horn switch contact contacts well, some of them are horn itself.

(2) voice hoarse. Mostly due to poor contact plugs, especially the various contacts around the steering wheel, as a result of frequent use, easy to make contacts to wear.

(3)Completely does not ring. First check to see if the fuse is blown, then unplug the speaker plug, use Autel MaxiSys Pro MS908P or Autel Maxidiag Elite MD702 tools to detect whether horn switch is electricity. If there is no power, check the horn and horn relay harness; if there is electricity, it is the speaker itself is the problem, then you can try to adjust the adjusting nut on the horn to see if sound, if still does not ring, you need to replace the speaker.
