Power Door Locks

When a Door Lock Switch is activated in the Power Door Lock system, both doors will lock or unlock in unison. The locks are operated by reversible Actuators. The Door Lock Switches operate the Actuators by applying a ground input signal to the Body Control Module (BCM), which commands the Door Lock Actuators to lock or unlock. When either the LH or RH Door Lock Switch is moved to "LOCK," the BCM switches battery voltage to both Door Lock Actuators at CKT 259. The LH and RH Actuators are grounded through CKT 694 and CKT 1663, through the BCM and CKT 650 to ground G200. When either the LH or RH Door Lock Switch is moved to "UNLOCK," the BCM switches battery voltage to both Door Lock Actuators at CKT 649 and CKT 1663. Both Actuators are grounded through CKT 295, through the BCM and CKT 650 to ground G200.
