Central Door Locking Switches

Central Door Locking Switches







A momentary action switch mounted on the fascia allows for central door locking/unlocking from within the vehicle. The switch is mounted adjacent to the clock.

Input/Output

The input from the central door locking/unlocking switch to the BCU is either zero volts or an open circuit. Zero volts indicates the switch is closed. An open circuit indicates that the switch is open. When the BCU sees an open circuit, it pulls the input high internally.

The central door locking/unlocking switch has a dedicated signal input to the BCU. This allows the BCU to identify the lock/ unlock request.

TestBook provides the ability to monitor the real time state of the central door locking/ unlocking switch.
