Smart Lock Function Does Not Operate On Driver Door

SMART LOCK FUNCTION DOES NOT OPERATE ON DRIVER DOOR

CIRCUIT DESCRIPTION
When the touch sensor inside the driver door outside handle is touched, the smart ECU sends a request signal to the driver door outside oscillator. The smart key receives this request and transmits its ID code.
Upon receiving the ID code, the smart ECU determines that the smart key is outside the vehicle and sends a lock signal to the driver door lock assembly through the instrument panel J/B (multiplex network body ECU).
