SMART CANCEL SWITCH DOES NOT OPERATE

CIRCUIT DESCRIPTION
Smart unlock function:
When an outside oscillator receives a smart key output ID code and the smart ECU confirms the ID code, the smart ECU outputs a SEL signal (Lo when output) to the outside oscillator to change the touch sensor inside the door outside handle to unlock standby condition. When the touch sensor is touched, the outside oscillator outputs a SENS signal (Lo when output) to the smart ECU. Then, the smart ECU sends an unlock signal to the appropriate door lock assembly through the instrument panel J/B (multiplex network body ECU).

Smart lock function:
When the lock switch on the outside door handle is pressed, the smart ECU sends a request signal to an 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 appropriate door lock assembly through the instrument panel J/B (multiplex network body ECU).
