Pinpoint Test E : B126A:01: Notes
Refer to Remote Keyless Entry and Alarm for schematic and connector information.
Normal Operations and Fault Conditions
The BCM sends voltage signals to the door lock control switches through the lock and unlock input circuits. When the lock or unlock switch is pressed, the corresponding voltage signal is routed to ground, signaling the BCM to lock or unlock the doors. The door lock control switches have a dedicated ground circuit.
