VAS 5054A VW AUDI SKODA SEAT Diagnostic Tool Good Quality

Today I will teach you some diagnostic methods for Nissan cars:
A frozen air conditioning Sylphy.
Failure phenomenon: the car for a period of time, for example, 20 minutes, air conditioning will not come out, but the noise is very large, it is obvious that the evaporator icing, blocking the wind out of the.
The diagnostic process for repair of evaporator icing Sylphy is very early, someone had summarized the principle of the first, simple, complex, the first change of refrigerant, in strict accordance with the 450 grams of filling the new refrigerant, and then not, replace the expansion valve, then replace the compressor. But for this car, the replacement refrigerant has no effect, replace the expansion valve, has no effect, the total does not replace the compressor. Finally, we open the expansion valve, observe the structure, pay attention to the expansion valve at the bottom of the adjustment screw, a screw inner six angle, the original expansion valve can be adjusted. We are based on the principle, tighten the screws, and then test results.
Solution: adjusting the expansion valve screw, you can open the valve to reduce the degree of expansion, reduce refrigerant flow, reduce the pressure of the low pressure pipe, thereby reducing the output of the compressor, so that the evaporator is not easy to freeze.
Two. 1.6 Nissan engine is difficult to start (Livina. Tiida Sylphy.)
Fault phenomenon: whether engine or refrigerator engines are difficult to start the phenomenon
Confirm the fault: start the engine test, about a few minutes after the engine before the engine, the engine is indeed difficult to start.
Initial inspection: the special fault detector test, no fault code display; read data flow, are also normal.
Diagnostic process: pull off the coolant temperature sensor wire side connector after starting the engine, the engine can immediately start the machine. However, after the replacement of the coolant temperature sensor test, the fault is still.
Remove intake pipe after the solar term door is, when starting the engine, to the inlet pipe is sprayed into a little carburetor cleaning agent, mixed gas enrichment, the engine can immediately start a machine. Check the engine intake part, no leakage phenomenon. The data flow of the engine starting is read by the Nissan special fault detector. The basic fuel injection pulse width is 4.1ms, and the actual fuel injection pulse width is 5.6ms. The data flow during the start of normal vehicle engine was read, and it was found that the actual fuel injection pulse width was about 9 Ms. It seems that the fault reason is that the fuel injection quantity is too small at the start of the engine.
Solution: to the engine ECU self-learning can be ruled out. Engine ECU self-learning methods are as follows:
(1) engine warm to normal operating temperature;
(2) the engine speed is maintained at 4 800r/min below, after the start of the vehicle 0KM/h urgent acceleration to 60 km/h;
(3) repeat steps (2), operate more than 2 times;
(4) after the engine is switched off, it can be restarted.

Honda Odyssey vehicle body shake when driving

A 2002 Honda Odyssey with mileage over 220,000 km, configured MAXA automatic transmission. The car with 70km/h constant speed appears intermittently vehicle body shake.


Fault Diagnosis: The car constant speed, when torque converter into lock-up initial stages, the body appear obvious shake; when torque converter complete lock-up, the body shake disappear. Check the automatic transmission fluid, the amount and quality of oil is normal. Use Honda HDS HIM self-diagnosis the automatic transmission system, no fault code.

Road test, at the same time check the changes of data stream, found when appears lock-up clutch command, the vehicle body shake appear immediately, the whole process does not appear skidding. It showed transmission hydraulic system is working properly, the problem is in the torque converter.

Remove the transmission assembly, cut open the torque converter to check, found the torque converter is refurbished. Measuring the torque converter cover internal lockup clutch working surface flatness, the maximum amount of fluctuation does not exceed the standard value. Check the lock-up clutch, the friction surface not flat, there is a raised portion, that is caused by improper operation.The common reason is sticky sheet mold used improper selection or mold itself is not flat. Replace the torque converter, the fault completely ruled out.

The direct cause of vehicle body shake is lockup clutch friction plates not flat. In the early lock-up clutch cement, friction plates not flat will caused the friction appeared hopping, cement impact make the body shake. In order to make sure the maintenance quality of the automatic transmission, have to use special tool, and check the special tool itself is good.

A mileage of about 110,000 km, with ATK engine FAW-Volkswagen Jetta Avant Garde GiX car. When the engine speed reaches 3000r/min performed shifting, engine is not running smoothly, the vehicle have punch feeling, high-speed driving weakness.


Fault Diagnosis: use VAG VAS 5054A diagnose the the engine electric control system, no fault code memory. Check the ignition coils, harness connector reliable connection. Remove the spark plug of each cylinder to sparkover experiment, sparks strong. Remove the fuel filter, found the filter is dirty, suspect the fuel quality of the fuel tank is poor or oil plug. So after removed the fuel tank, thoroughly clean fuel pump strainer and fuel tank, re-add high quality clean fuel, and replace the fuel filter, install fuel pressure gauge to measure the fuel system pressure, when engine idling the fuel pressure is 250kPa, when rapid acceleration is 300kPa. To keep the pressure at above 200kPa, the measured values were normal. Use the electrical barrier of multimeter to Measure the fuel injector resistance is 15Ω, meet the specified value.

Disconnect throttle position sensor harness connector, found that the plug connection is reliable, the pins in good contact, but have some dirt near the throttle. After cleaned, use VAS 5054A check engine speed when the throttle closed or open sensitive reaction and accurate. Check oxygen sensor voltage 0. 1 ~ 0. 8V changes, proved oxygen sensor is working properly. Check the crankshaft position sensor, after measuring, the signal output is normal, the harness connector in good condition. Performed parts replacement test, after replaced the control unit, intake air pressure sensor, throttle body and the ignition coils, the fault persists. Check each sensor element plug, found 2 knock sensor harness connector plug and socket looks something was amiss. After pluged two knock sensor plug back in place to test, the results returned to normal, the fault completely ruled out.

Later after understanding to know that the car had been replaced knock sensor. Since the model of two knock sensor plugs as easily reversed, although reversed but not affect the engine normal start, but after 2 connector reversed cause the control unit receives the wrong signal, causing the engine work abnormal.
