DOOR LOCK: SMART KEY SYSTEM: 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 RH is touched, the certification ECU sends a request signal to the door electrical key oscillator. 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 passenger door lock through the instrument panel junction block (multiplex network body ECU).
