DOOR LOCK: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: Rear Door LH Entry Lock Function does not Operate

Rear Door LH Entry Lock Function does not Operate

DESCRIPTION

When the touch sensor inside the outside door handle rear LH is touched, the multiplex network door ECU rear LH (rear door LH ECU) sends a request signal to the door electrical key oscillator rear LH. The key receives this request and transmits its ID code. Upon receiving the ID code, the certification ECU determines that the key is outside the vehicle and sends a lock signal to the rear door LH lock through the cowl side junction block RH (multiplex network body ECU).
