Entry Lock Function does not Operate on Driver Side Door: Description

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