DOOR LOCK: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: Rear Door RH Entry Lock Function does not Operate
Rear Door RH Entry Lock Function does not Operate
DESCRIPTION
When the touch sensor inside the outside door handle rear RH is touched, the multiplex network door ECU rear RH (rear door RH ECU) sends a request signal to the door electrical key oscillator rear RH. 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 RH lock through the cowl side junction block RH (multiplex network body ECU).
