Operation CHARM: Car repair manuals for everyone.

General Information

IMPORTANT: The power door lock system is controlled by the Body Control Module (BCM), which contains the Retained Accessory Power (RAP) subsystem. The RAP subsystem enables the power door locks for up to 10 minutes after ignition is turned off and both doors remain closed or for 35 seconds after exiting the vehicle and closing the doors. The power door lock system is also enabled whenever a door is open, unless the lockout prevention feature is enabled and the ignition key is in the ignition. For a complete understanding of RAP operation, refer to Retained Accessory Power. Accessory Delay Module

When a door lock switch is activated, both doors will lock or unlock in unison. Each lock can also be operated manually. The locks are operated by reversible actuators. The door lock switches operate the actuators by applying a ground input signal to the BCM, which commands the actuators to lock or unlock. When either the left or right door lock switch is moved to the lock position, the BCM switches battery voltage to both actuators from the GRY (295) wires. The left and right actuators are grounded through the TAN (694) and GRY/BLK (1663) wires, through the BCM and the BLK (650) wires to ground G200. When either the left or right door lock switch is moved to the unlock position, the BCM switches battery voltage to both actuators in the opposite direction from the TAN (694) and GRY/BLK (1663) wires. Both actuators are grounded through the GRY (295) wires, through the BCM and the BLK (650) wires to ground G200.
