DTC B1349: Door Lock Actuator Ground Feed Circuit (Open): Description

WARNING: This page is about a different car, the 1999 Buick Regal and 1999 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

Body Control Module (BCM) receives ground for door locks through circuit No. 1750 (Black wire). DTC B1349 will set when BCM detects an open in circuit No. 1750 (Black wire) or is open internally for more than 0.3 second. No driver warning message will be displayed.

If conditions for malfunction no longer exist, history DTC will clear after 100 consecutive ignition cycles. DTC B1349 will also clear when conditions no longer exist or scan tool is used to clear codes.

NOTE: If DTC B1349 is a history code, problem may be intermittent. Wiggle wires while performing the following test.

NOTE: When ignition switch is turned to RUN position with BCM disconnected, PCM-related DTC P1626 will be set. After BCM repair is completed, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
