Driver Side Door Entry Lock Function does not Operate: Description

When the touch sensor inside the outside door handle LH is touched, the certification ECU sends a request signal to the door electrical key oscillator 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 driver door lock through the instrument panel junction block (multiplex network body ECU).
