How to maintain the car battery in summer

Summer car battery maintenance is regularly use OBD Diagnostic Tool inspection maintenance, trailer coupling corroded battery case must be promptly treated to eliminate hidden dangers.

The heat of summer, the car in high temperature and under the hot sun, there will be a series of problems caused by high temperature and failure, often seen in the case of fire, causing casualties. Vehicle in the sun for a long time, the temperature inside the car sharply increased. It has been shown that when the outdoor temperature in 36 degrees Celsius, the car as long as two hours of exposure to the sun, the car will increase to 68 degrees Celsius temperature. It can be imagined, without the use of the Launch X431 IV GX4 Master or Launch X431 Diagun III tool to check the battery, in this environment is easy to short-circuit and spontaneous combustion.

How do the clean-up battery: lead to car battery pile head corrosion reason is battery liquid sulfuric acid. When the engine, generator will recharge the battery, the battery will produce hydrogen bubble, some acid composition will be followed by a hydrogen discharge battery, especially in charging system, such as the generator voltage is too high or charging without restraint, leads to charge excessive and so on, it will lead to a lot of sulfuric acid components into the battery on the panel to, then the two pile head will corrosion.

In addition, when the daily driving, before leaving the car, check to make sure that all lights and other electrical vehicle (such as radios, CD) has been shut down because of a long parking time will run out of battery power. Car battery to regular maintenance, carefully check the battery bolts through the vent plug, the battery will produce a large number of hydrogen, oxygen gas, once the exhaust valve failure or blockage, the pressure is too large, may cause explosion.

To avoid sparks, the pile head before the demolition of the battery, to all automotive electrical and ignition turned off, then use Autel MaxiSys MS908 or Xtool PS2 tool to check, and must remove the negative pole first, then remove the positive pole. In the back of the pile head, the positive electrode and the negative electrode. In addition, if you are not sure, it is best to consult the original operation of the factory in the process of safety precautions.

The cause of the lubricating oil consumption too fast

Just fill the oil to the car, not a few days to check the dipstick and found that missed a lot of oil, in normal use appear this kind of problem is not normal phenomenon, called abnormal oil consumption, what are the reasons and how to deal with it? Need to use the Auto Diagnostic Tool?

The reason: the consumption of lubricating oil is divided into two kinds of normal consumption and non normal consumption. Normal consumption is because between the piston and cylinder wall as long as the movement will gap exists, regardless of gap size, there will always be a part of the oil with the up and down movement of the piston is brought into the combustion chamber with the mixture together burn. This normal consumption, the general consumption should be less than fuel consumption 1% or less. You can use the Launch X431 GDS or Launch X431 V Pro tool to check it out.

Non-normal consumption is usually because there is a fault caused by the engine itself. There are three general reasons:

First, the cylinder wall wear gap is too big, lubricating oil through the clearance between the piston and cylinder wall to burn a lot into the combustion chamber. When the tube was evident with blue smoke from the exhaust phenomenon.

Second, the oil pan and oil seals Mifengbuyan, causing oil leakage.

Third, the engine cooling bad, the engine overheated, so a lot of oil and gas generated by the crankcase ventilation tube into the inlet and the mixed gas is burned together.

Thus, if you find that the oil consumption is too fast, the engine of a system failure. To use the Autel MaxiSys MS908 or Autel MaxiDiag Pro MD801 tool to find out the reasons for repair. Of course, if you use some of the inferior oil will also appear to oil consumption too fast. So be sure to use the regular factory production of lubricating oil. In order to avoid the damage caused by engine.

BMW X1 coolant temperature warning light alarm

A driving range of about 40000 km, models E84, engine type of N46 2013 BMW X1 sport-utility vehicle, there are a lot of friends reflect the car speeding coolant temperature warning light alarm, need to use Auto Diagnostic Tool detection.

Maintenance personnel to check the expansion tank in the cooling fluid is missing, there have cooling liquid leakage traces, doubt cooling system has a leak, the system for pressurized testing, good sealing.

Detecting an engine control unit, found no fault record on coolant temperature. Use the Launch X431 GDS or Launch X431 V Pro tool control cooling fan operation, to determine the fan work normal. N46 type engine water pump is a mechanical driver, as long as the engine running it will work. So will check of the opening of the emphasis on thermostat, cooling system, circulation and cooling system on the gas resistance.

In view of the vehicle mileage is not much, so doubt any wind resistance in the cooling system, cooling fluid according to standard process of adding and steam. And adjust the liquid level to the standard position. Road test, the test member come back soon, reflect the coolant temperature is high, and connect the thermostat pipe is cold. Read the circuit diagram, see the thermostat controlled by the engine control unit. In fault diagnosis instrument to observe the thermostat signal waveform, compared with the normal car found waveform, show that no control problems. Doubt thermostat has a problem, replace the thermostat test, fault is still.

After just tried to touch his hand car radiator, we found the upper and lower temperature difference, indicating that the coolant is not flowing from the interior, replace the radiator test, fault still exists. Promote the flow of the coolant pump, use Autel MaxiSys MS908 or Autel MaxiScan JP701 tool to check the pump, the pump impeller was found not rotated. Remove the water pump turned by hand, found stuck, replace the water pump test, troubleshooting.

Buy second-hand car need to pay attention to matters

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.

Car over speed humps Tips

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.

Oil tank filled full oil has four big taboo

Many owners like to say fill full when fill oil, usually come added to jump the gun, always want to continue oil into the tank, in order to scrape together a integer. Do you know? Through Auto Diagnostic Tool check data show that gas tank is too full can damage the car, and there are serious damage, there are four points of damage:

1, easy to cause fire
If you add too full of oil, oil is easy to overflow from the tank vent. A waste of gasoline, in case of spilled gasoline encounter fire, it is easy to fire, threatening the safety of life!

2, easily cause clogging of the vent
Once the vent plug, it will generate a negative pressure within the fuel tank, causing oil to poor, even for non-oiled. Car situation appears just after the addition was complete oil beat the fire engine, or a jump a jump phenomenon at high speeds, it is possible that due to the gas tank too full due.

3, canister constitute a hazard
Into the carbon canister is a liquid rather than a gas vapor, carbon canister would constitute a hazard. The canister is to reduce vehicle fuel tank, carburetor gasoline evaporation apparatus matter emissions. Through the Launch X431 V Pro or Launch X431 Diagun III tool check normal carbon tank should be above 50000 km, but after the immersion, immediately scrapped!

4, volatile gasoline easy carcinogenic
The activated carbon canister, generally near the outer circulation air inlet, when the oil is too full, canister saturation, pressure too high and pressure relief exhaust, containing gasoline constituents of air into the compartment, uncomfortable "gasoline" always around you. Oil and gas components have been confirmed to contain benzene and other carcinogens, if every time so that the car refueling, through Autel MaxiSys MS908 or Autel MaxiDas DS708 tool checks show will increase the risk of cancer.

Why the car circuit system will catch fire

Automobile circuit usually have starting circuit, power supply circuit, lighting and light signalling device circuit, ignition circuit, auxiliary circuit device, electronic control system circuit, instrument information system circuit composition. So many friends in the process of driving the car will be found auto electrical systems fire, when people are very anxious, do not know what is going on. So today we analyze why the car circuit system catch fire, of course, need professional OBD Diagnostic Tool to be checked.

Among the car ignition accident, car circuit fire occupy a large proportion of spontaneous event. This circuit is aging and the car circuit load is too high is the reason. First, since the engine work, the ignition coil high temperature, easy to make high-voltage ignition wire insulation softening, aging, crack damage, ignition high-voltage insulation breakdown easily produce high-voltage leakage, short circuit leading to spontaneous combustion ; second, the car has a growing number of electronic control technology, intelligent vehicle widely used, Launch X431 Diagun III or Launch X431 Creader VII+ tools to detect data show a substantial increase in the power consumption of automotive electronics accordingly. Auto electrical systems on limited load space, automotive microcomputer, electronic components, various sensors circuit systems are likely to cause damage, since a large number of cars increase the variety of additional electronic equipment, may also increase the burden on car circuit, causing spontaneous combustion fire.

Car circuit maintenance is very important, a lot of the cause of fire is circuit aging, many friends think now car maintenance is the car's appearance maintenance, do essential for the maintenance car circuit, you can also use Autel MaxiSys Mini MS905 or Autel MaxiSys MS908 tool regular inspection car circuit to ensure the safety car circuit.

How to maintenance of automatic transmission oil filter

Filter is the key projects when we maintenance to the car, oil filter, air filter, fuel filter, the so-called "three filter" Conservation has always been a point of attention. In addition to these three common commonly used filters, there is a transmission oil filter, its maintenance methods very few people know, is very simple, just use the OBD Diagnostic Tool can be.

The conservation process in the daily inspection car, the car transmission oil filter is rarely mentioned, unless damaged, affecting the transmission operation, otherwise, its maintenance is easy to be overlooked in. Because in most cases, transmission oil filter is not like oil, air or fuel filter as easy to replace. In fact, since the automatic transmission oil, ATF filter is a device for protecting the second main assemblies, so it should be kept clean or replaced in time according to the Launch X431 V Pro or Launch X431 IV GX4 Master equipment recommended by the manufacturer.

The automatic transmission usually paper filter, felted membrane filter or oil filter to filter out the dirt. Asian carmakers like using a membrane filter; and European and American manufacturers are more inclined to paper or felt filter.

Some car manufacturers have introduced long-life or maintenance-free transmission. The transmission no dipstick device and its normal maintenance, ATF and filter replacement cycle of up to 160,000 km / h.

For the ATF filter, you can't judge the performance of the filter, unlike oil filter to be replaced follow along as oil, unlike the air filter, you can take it down and clean it, transmission oil filter can only rely on inspection and maintenance process maintenance personnel inspection tips. It also reminds us that we must have understand of basic car maintenance knowledge, or you can use the Autel MaxiSys Pro MS908P or Autel MaxiSys MS908 professional equipment to check the filter work performance.

Anti-lock braking system ABS function introduction

Anti-lock braking system ABS can be installed on any car with hydraulic brakes. It is the use of the valve body of a rubber balloon, when put on the brakes, giving the brake oil pressure, flooded to the ABS valve, when the airbag use compartment in the middle of the air pressure to return, so to avoid wheel lock dead center. When the wheel is about to reach a dead lock, brake oil pressure the effects of repeated balloon, under the OBD Diagnostic Tool check, found in a matter of seconds can be 60 ~ 120 times, in does not stop brake, relax. ABS is composed of wheel speed sensor, engine speed sensor, solenoid valve, computer and hydraulic control unit (hydraulic regulator), and its characteristics are as follows four:

1, ABS with excellent performance and self diagnostic capabilities, you can rest assured that use. In addition, the use of ABS and the common brake system using almost the same, braking to foot on the brake plate normal braking can be, ABS will own the brake hold at the optimal point.

2, the car brakes, the braking force of the four wheels are different, if the car's front wheels to lock, the driver can not control the direction of travel of the car, prone to risk of a collision, if the first locking the rear wheels, can appear the skidding, tail flick, if installation of ABS, can avoid four wheel is locked, Launch X-431 PAD or Launch X431 GDS tool can detect ABS data, the ABS system improve the stability of the vehicle in the braking process;

3, compared with the conventional braking system, under the state of emergency braking, ABS can make the wheel in both rolling and drag, which greatly increases the tire and the ground friction and shorten the braking distance, namely the so-called optimal braking point or region, while the ordinary brake system is unable to do this;

4, It is proved that the wheel fully locked will cause tire cup type wear, make the uneven abrasion on the tire surface, thereby increasing the tire wear and tear.

Thus, ABS anti-lock system, can avoid the braking when the direction is out of control and wheel sideslip, make the wheel when the brakes are not locked, don't let the tire friction with the ground at one point, so as to increase the friction, in the Autel MaxiSys MS908 or Xtool PS2 tool checks found, ABS system makes the brake efficiency of 90% or more, while reducing brake consumption and extend brake drum, disc and double the life of the tire. Vehicles equipped with ABS in dry blacktop, rain, snow, skid resistance reached 80% - 90%, 30%, 10%, 15% - 20%.

Honda car air conditioning refrigeration malfunction maintenance

Honda automobile air conditioning refrigeration failure phenomenon. After filling refrigerant. Open air conditioning, on the electromagnetic clutch compressor suction no, idle speed is high and low (850 r/min to 1100 r/min), the fan rotation is normal, but poor refrigeration, you can see the real-time data by OBD Diagnostic Tool.

Detection of electromagnetic clutch of the compressor line, the voltage is normal. After the failure of the circuit is determined, the high and low pressure port of the air conditioning system is measured by using multi meter.. As a result, the pressure at high and low pressure is abnormal, and the pressure is high and low, and under the Launch X431 Diagun III or Xtool PS2 tool checked, the engine was found to rotate abnormally. Ask the driver, there is no phenomenon before the refrigerant filled, and then suspect that there may be too many refrigerants.

Gradually sucked out of a portion of the refrigerant, the engine speed changes observed in the tool to see a few bubble, accelerate to 1700 r/min when bubbles disappear, troubleshooting.

When the air conditioning system of the refrigerant injected too much, it will reduce the flow of refrigerant in the system performance, causing the compressor malfunction, poor refrigeration, the engine idle speed instability, You can check with the Autel MaxiSys MS908 or XTOOL VAG401 tool before you inject the refrigerant, and it will remind you how many refrigerants you should add.

Fuel filter basic maintenance of common sense

Fuel filter replacement cycle
Fuel filter replacement is recommended once every 10,000 kilometers, built-tank fuel filter replacement 4W - 8W km. The differences between different models of the maintenance cycle may be slightly, your car when need to replace the maintenance, please via OBD diagnostic tool understand.

To conduct a comprehensive maintenance, fuel filter and oil filter, air filter, machine commonly replaced at the same time. Disassembly to replace the fuel filter is more complex, not easily do it yourself, you need go to repair shop and let professionals to operate install.

The necessity of replacing the fuel filter
Fuel filter according to the different filter can be divided into gasoline fuel filter and diesel fuel filter, home cars use a fuel filter, fuel filter are divided into built-in and external tank.

The vehicle with the use of the growth of the age, with increased mileage and fuel filter long-term work, to reach a certain life cycle, will cause the car to accelerate weakness, increased fuel consumption, noise increase, reduce handling performance, you can also use the Launch X431 GDS or Launch X431 V Pro check the fuel filter performance.

Fuel filter purchase considerations
1, before the purchase of goods, be sure to verify the car's model, displacement and other information to ensure that the correct types of accessories available. You can check the maintenance manual.

2, high quality fuel filter, poor-quality fuel filter often leads to oil poor, lack of motivation or even turn off the car. No filter impurities, a long time, oil and fuel injection systems may cause corrosion damage.

3, when the feeling of speed significantly reduced, poor acceleration engine, cars with weakness, it may be already clogged fuel filter, and the need for timely use Autel MaxiSys MS908 or Autel MaxiSys Mini MS905 tool checks.

How to clean the car engine to improve performance

Found in the auto repair factory repair, car washing people in a continuous line, but few people clean the engine. Said engine is the car's "heart", so clean the engine is also very important, you can use the Auto diagnostic tool to check whether the engine is good, to avoid security problems.

Due to the use of the car environment is very complex, the engine used for a period of time, into the engine room of dust and impurities in the engine surface carbon and other harmful substances, if long time does not clean up these harmful substances, it will be transformed into sludge, penetrate the surface of the engine, will not only cause rusting metal parts, plastic parts deformation aging, but also lead to engine power reduced and fuel consumption increased, and even produce a variety of oxidation due to damage to the engine, if you are unsure, you can use Launch X-431 PAD and Launch X431 V Pro to be checked.

Therefore, to achieve the objective of saving, it is necessary for the engine regularly cleaning.

Cleaning the engine can ask the professionals, you can also do it yourself by following the procedure performed. First Auto Electric mask with plastic film, then the film with a wet towel on top of the lid to prevent high-pressure water rushed into the distributor, causing the car difficult to start. By the engine side from top to bottom will be attached to the class dirt engine and engine room side appearance rinse with water cannons; next engine external cleaning agent evenly sprayed around the engine and engine compartment.

Cool for about three minutes, with a fiber brush to clean all the parts that can reach the engine room, and rinse with water cannons quickly brushing off the dirt. Then external engine cleaner sprayed on engine surfaces (steps ibid.). Until the engine looks clean. Finally, rinse the engine with a wet towel and dry machine with hands REACH dry.

In addition, proper selection of some gasoline additives products can also reduce carbon deposition engine oil produced, when cleaning, avoid the time-consuming, in a timely manner use the Autel MaxiSys MS908 and Autel Maxidiag Elite MD701 auto tools, to improve the performance of the car there is a certain Help.

How to timely discovery brake failure

For brake failure, we may only appear in the braking force of brake or abnormal noise will be found. If you are traveling at high speed and other conditions, it is very dangerous! In fact, we usually use the Auto diagnostic tool you can determine the brake system problems, and these details are likely to be ignored for everyone.

First, when the brakes shudder
This situation occurs mostly in old car, because the use of wear, brake disc surface roughness has a certain degree of misalignment. It is proposed that, as the case opt lathe sanding disc technology, or replace the brake pads.

Second, when the brake quickly stopped, the steering wheel will always to the side deflection
In fact, this situation is what we called "partial brake", the main reason for the failure is about the brake system Cylinder uneven forces on the brakes caused. And in the process of moving due to the rotation speed brakes, wheel cylinder uneven role in the fast friction difference is very small, we can hardly feel it. But when the vehicle stopped quickly when the difference is obvious, that the speed of the wheel stopped on one side of priority, the steering wheel will deflect. This may need to Launch X431 GDS and Launch X431 V Pro tools to detect.

Third, driving need heat 10 minutes before the brake force
Is provided by the engine brake system pressure to promote calipers grip brakes, or push the brake drum friction brakes. So like the above conditions, may provide pressure transmission pipelines loss of pressure occurs, resulting in not timely provide braking force. This situation should be checked at the pretext of the vacuum booster hose and brake master cylinder engines have cracks or loose condition.

Fourth, the brakes do not return
Step on the brake pedal, the pedal does not rise, no resistance, a phenomenon that the brakes do not return. Need Autel MaxiSys Mini MS905 and Autel MaxiSys MS908 tool to determine whether the brake fluid missing; whether the brake wheel cylinders, pipes and joints leak; whether the master cylinder, slave cylinder parts damaged.

Toyota car ignition key registration steps

After the new replacement parts, Toyota cars ignition key registration method:
1) After the engine ECU and the whole car lock core replacement, anti-theft alarm indication lamp flashes.

2) After the anti-theft alarm indication lamp flashes to confirm, insert a main ignition key (black) to the ignition switch.

3) About one second, burglar alarm light is off, the ignition key that registration is complete, then, You can also use the Launch X431 GDS and Launch X431 V+ Pro3 to check.

4) after the main ignition key registration is complete, burglar alarm indicator lights again.

5) anti-theft alarm status indicator lights after being confirmed, then pull out the ignition key. Insert two main ignition key (black) to the ignition switch.

6) About 1 seconds, burglar alarm light is off, the ignition key has been registered. After registration is complete, burglar alarm indicator lights again.

7) anti-theft alarm status indicator lights after being confirmed, then pull out the ignition key.

8) Insert the first three deputy ignition key (gray) to the ignition switch.

9) About 1 seconds, burglar alarm light is off, the ignition key has been registered.

10) After Unplug this ignition key, if burglar alarm LED flashes, which means that the registration is successful. If you want a quick registration, you can use the OBD diagnostic tool.

Note:
1) For the anti-theft ECU and engine ECU set as one unit (ECU), regardless of model, the ignition key of the registration of such methods are applicable.

2) registered ignition key sequence: the 1st main ignition key, the 2nd main ignition key, the 3rd Vice ignition key. If the ignition key to change the registration order, it can not properly registered.

3) If you do not make the correct registration method will cause the engine ECU recognizes only a handful of the ignition key, the ignition key into the ignition switch first one, so the other two could not start the engine, you need Autel MaxiSys MS908 and Autel MaxiDas DS708 diagnostic tool to repair cars.

How to solve the automotive air conditioning odor and refrigeration poor

Automotive air conditioning system is mainly based fluoride as the medium through the system pressure transformation, to reach refrigeration purposes. It consists of the evaporation tank, an expansion valve, a compressor, a blower, a condenser, a drying tank and lines. Evaporation tank is working in air conditioning systems work properly in cold environments encountered relatively hot outside air will produce water, which is in the evaporation tank structure, design outlet truth; wet environment evaporation tank and ventilation ducts and dust on the surface provides a breeding ground for mold and fungus favorable conditions for mold and fungus will soon multiply to mold and fungus group group of organisms that produce rotting smell that smell will open with the air conditioning, mixed in the air which, contaminate the entire car interior, occupants often make people feel uncomfortable, but also people have severe dizziness, chest tightness and discomfort. Early use of OBD diagnostic tool that can identify and solve such problems in advance.

Auto repair industry in order to solve this problem, is often demolished evaporation tank cleaning surface evaporation tank in order to achieve this approach fundamentally eliminate the odor, but every once demolished, they need to put fluoride, fluorine and other installation and processing a series of processes, cumbersome and technical difficulty, and low labor productivity. Because evaporation tank often work in a wet environment, and humid environment can easily produce mold, just to clear the air conditioning mold, over a period of time may have odors occur.

In addition, the automotive air conditioning systems as well as common problems and slight leakage of fluorine refrigerant adverse phenomenon, which also adds a lot more difficult to repair, Launch X431 V+ Pro3 and Launch X431 IV GX4 Master automotive tools can be easily resolved.

Automotive air conditioning system, air conditioning piping in power fluoro circulating from the compressor, the compressor lubrication oil is accomplished by fluorine. In the pipeline, together with the fluorine fluorine oil circulation to the entire system, which directly affect the flow of circulating air conditioning cooling performance, fluorine and fluorine oil for a long time at high temperature and high pressure and low temperature and pressure in the changing environment, coupled with the compressor work long hours under wear metal debris, etc., will produce gum and other deposits, some of these sediments are filtered out, part of the precipitation in each pipe, a small amount of the deposit does not affect the air conditioning cooling performance, but the deposition increasing material will affect the circulation flow rate of fluorine, which affects the air conditioning cooling performance. Air conditioning maintenance, we exclude the circuit, mechanical, pressure, temperature (including engine temperature) and fluorine and other reasons, the air conditioning refrigeration is still bad, we can use Autel MaxiSys MS908 and Autel MaxiSys Mini MS905 tool, the problem would be easily solved .

How to maintain the car battery

Battery plays an important role in the automobile use process, if it can not supply normal, car will not start running, while the car's power consumption in winter than in other seasons is much greater, and the battery is also afraid of low temperature, low temperature battery electrical capacitance is much lower than the normal temperature. So after entering the winter, special care for the battery is quite necessary, the battery life of about two years, if you use OBD Diagnostic Tool to check and timely care can prolong life.

First, external battery with a damp cloth to wipe it again, the panel, on the stigma (ie, both positive and negative poles) of dirt, oil, white powder and so easy to wipe clean the dirt caused by leakage and apply special grease to protect trailer coupling, to prevent corrosion.

The second step is to check the battery electrolyte leakage or deformation phenomenon. Some models are equipped with all maintenance-free battery, relevant or labels, do not disassemble the battery for this, if there is leakage, deformation of the phenomenon, it is best to go to the pits to solve. Maintenance-free battery life of about two years, expired on the use of Launch X431 Diagun III tool to check the battery voltage load voltage and starting performance, promptly replace if necessary.

The third step, if the car is parked in the open air or cold a few weeks do not, you should remove the batteries, stored in a warmer room, to prevent freezing damage to the rear battery self-discharge. When the ambient temperature is below minus 10 degrees, fully discharged battery will freeze, you must thaw the frozen processed before charging the battery, or directly charging may cause an explosion. If this happens, it is best to use a professional car repair small current slow charging stations.

So, in fact, battery maintenance is not difficult, you can try to use the owner Launch X431 GDS and Autel MaxiSys MS908 diagnostic tools, car to do maintenance on a regular basis, to extend its working life.

4 Defects of Waxing and the Connection with the Car Damaged "Skin"

Waxing, as for one of the traditional programs of the car beauty, is the choice of the car owner before choosing a car tool online store for diagnosing their cars. But many may ask whether it has been well protected with often waxed. Then let’s look at the damage brought by improper waxing and we hope it will attract your attention.
1. Amounts of wax, easy to wear the paint!
The Shortage of Auto Paint Maintaining Methods:
1.1 Easy oxidation
Professional automotive beauty points out that waxing and closure glaze, as two traditional paint curing methods, they are sure to protect your car paint at a period time. It takes the oil as solvent, which is much easier to produce oxidation and form the “resonance” with the car paint.
