A driving distance of about 5000km, equipped with EA888 third generation 2.0L CUG engine of the new public Tougou L. The car was wiped off by the accident on the right rear part, installed in the rear bumper right end of the door opening device control unit J938 shell damage, replace the new Launch X431 PRO3 the foot movement after the tail gate can not automatically open. So the old J938 control unit installed, the tailgate was able to automatically open the next day after the kick automatically activated sensor function completely invalid.

    Fault diagnosis: connect VAS6154 query vehicle fault code, the system are normal, no system reported fault code. This car has come to me before the Launch x431 station has been replaced after the bumper sensor sensor G75. And G76. As well as the bumper inside the wiring harness, the results of failure and did not rule out.

    Want to observe the sensor sensor G750 and G760 sensing data through the data flow, and would like to use the data to analyze the fault location, the result is disappointing, the data display "function is not available."

This gives the maintenance of a certain degree of difficulty, the sensor itself and the line X431 Pro mini tablet without any reference without failure, feeling no force to hand.

    The driver must carry a legal key, in the range of 1m from the sensor, to the bottom of the bumper there is an upward kick of the action, and to recover. By the sensor sensors G750 and G760 sensor driver's intention to open, send a letter number; by the keyless X431 MINI entry into the authorized control unit antenna to locate the key, when the detection of a legitimate key, will activate the tailgate automatically open.

Sensors G750 and G760 are Launch transmitted to the tail gate opening control unit J938 and are transmitted via the LIN bus to the KESSY control unit J965. The KESSY control unit starts the keyless entry antenna, identifies the key, and facilitates the CAN bus to the trunk Control single action 605 to pass information, and finally open the tailgate.
