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.
