DOOR LOCK: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: Front Passenger Side Door Entry Lock Function does not Operate
- Front Passenger Side Door Entry Lock Function does not Operate
DESCRIPTION
When the touch sensor inside the outside door handle front RH is touched, the certification ECU sends a request signal to the door electrical key oscillator front 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 front passenger side door lock through the main body ECU RH.
