Pinpoint Test E : B126A:01: Notes
Refer to REMOTE KEYLESS ENTRY AND ALARM SYSTEM 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. The BCM sends the lock or unlock request from the door lock control switch to the RFA module over the MS-CAN.
