Driver's Door Key Lock/Unlock Switches

Driver's Door Key Lock/Unlock Switches







The BCU uses the driver's door key lock/unlock switches to activate and deactivate the alarm system. Two separate switches are incorporated into the key lock of the driver's door.

Input/Output

The input from the driver's door key lock/unlock switches to the BCU is either zero volts or an open circuit. Zero volts indicates the key lock is in the lock or unlock position. An open circuit indicates the key lock is in the center position. When the BCU senses an open circuit, it pulls the input high internally.

The driver's door key lock /unlock switches have a dedicated signal input to the BCU. This allows the BCU to identify the lock/unlock position.

TestBook provides the ability to monitor the real time state of the driver's door key lock/unlock switches.
