Nissan X-Trail Car brake system failure

Mileage only 1500 km of Nissan X-Trail 2.5 sedan. The car often in gear will not go, need refuel can moving forward.

Fault Diagnosis: Test car, fault does exist, but use Consult 3 to diagnostic not found fault code, lifting the car did not drag brake phenomenon. Then by repeated test found that the fault only when hanging the forward gear will appear, especially even step on a few brake failure will all appear, and when the fault appear the brake pedal is harder than no power. When unplug the ABS plug the fault will disappears, back into the plug, fault appear again.

Will caused by ABS pump failure? But read the data stream, ABS not found abnormal, replace the ABS pump failure still exists, that means the problem should be on the signal of control ABS, but use NISSAN CONSULT 3 III not found fault code, that should be relatively large possibility of machinery. Just think when pulling the plug, ESP / TCS / ABS fault code is appear together, and cause this situation fault code C1145 is exactly related with this control; and the fault appear is after the car installed the floor glue, which are associated with these two is (deceleration G sensor), while it is control the car uphill braking delay. Again read data stream found, deceleration G sensor signal is -0.07, while in the ground should be +0.02.

Remove the center console check and found that the direction of the deceleration G sensor bracket installed backwards and there are significant deformation, adjust the bracket change the deceleration G sensor signal to +0.02 and installed test, troubleshooting.

The failure is due to the bracket not installed well, when the car driving on uneven road or even step on the brake, the deceleration G sensor signal will reach -0.08, and when the ABS monitored deceleration G sensor signal is -0.08 will to uphill braking control, so the fault will appears sometimes.

Mercedes-Benz E300 sedan Parktronic system failure

A 2010 Mercedes-Benz E300 sedan with M272 engine. The vehicle Parktronic system function failure. After the vehicle is started, hanging R block, front and rear radar screen all no display, front and rear monitor buzzer does not beep, reversing lights work properly.

Diagnosis: Connect MB Star C3 use the latest Xentry software to fast diagnose the car, the test results show that the PTS system fault information storage: D12B00, with the front Parktronic system warning indicator communication failure. Into fault code, click "test" to enter guide test menu, the system will guide test between PTS control module and the front PTS warning indicator line connection, will guide test the front PTS warning indicator power supply. Tested front warning monitor supply no voltage input when reverse gear turned on. Dismantling the lines between PTS control module located right front foot well and COMAND control module, found both sides of the wires non-conductive, and warning the monitor connection color and circuit diagram shown is not the same, that feel very puzzled. Could the lines connection be wrong?

Revisit the vehicle initial detection unit find, in addition to PTS control module has the current fault code can not be cleared, there also AAC air conditioning control module exist the current fault information of interior temperature sensor communication failure. Assumed the two parts of plugs are the same, and line plug backwards. Try holding the attitude, dismantling and check the two parts control lines, and confirm the assumption situation is the actual existing problems. No wonder, because this car is just the transfer from second-hand car market. when the actual repair this failure is almost zero. After the line is reset, PTS and air conditioning function returned to normal.

For PTS system repair, have the following experience for your reference:

If there is a component failure in PTS system(such as radar sensors, warning indicator), then the whole system will stop working;

The front license plate frame installation position not good or non-standard installation will cause PTS system false alarms;

PTS system under working conditions, touch or ear close to radar probes can feel or hear fluctuations;

For vehicles equipped with parking guide function or blind spot monitoring functions and other special features, the radar sensor model of the bumper middle and both sides is not same, can not be mixed, order with EPC number as the standard.

Audi A6L MMI black screen

An Audi A6L 2.4 (C6) with mileage of about 100,000 km MMI black screen, All about MMI button lights off, and the screen can not be use.

Diagnosis: test fault exists, and no sound, restart the MMI have no response, use VAS 5054A and latest ODIS 2.2.4 software to test, found multimedia module have fault code. Use ODIS inside data inquiry function found that the specific fault as follows:

(1) MOST system fuse damaged;

(2) plus the conversion parts, modified line;

(3) MOST system fiber optic system have fault;

(4) MOST systems some control unit damaged.

Based on the above reasons to fault diagnosis, after check this car without additional equipment, according ELSA check each insurance, no blown fuses. Use VAS 5054A check the system, there is no fault memory, MOST system components communicate properly, but can not normal enter, use guide function loop diagnostics, display the results as normal. But this time back to the vehicle self-diagnosis, all MOST control unit are appears no communication static fault code, because just only J794 have problems will may be cause all components of the whole system no communication, the remaining components malfunction not have this phenomenon, suspect that fault should be J794 failure caused, replace J794, fault is removed.

After replace J1794 then use VAG VAS 5054A to test, found many place have fault code. At this time just need use VAS 5054A cleaning the fault code is OK.
