B1349

CIRCUIT DESCRIPTION
The Body Control Module (BCM) GNDD ground circuit provides ground for all door lock actuators including the endgate actuators.

CONDITIONS FOR RUNNING THE DTC
The Body Control Module (BCM) GNDE ground circuit must be connected to ground.

CONDITIONS FOR SETTING THE DTC
The Body Control Module (BCM) detects the GNDD ground circuit is open for greater than 0.375 seconds.

ACTION TAKEN WHEN THE DTC SETS
The Body Control Module (BCM) stores DTC B1349 in memory.

CONDITIONS FOR CLEARING THE DTC
^ The Body Control Module (BCM) no longer detects the open circuit.
^ 100 consecutive ignition cycles have been recorded without the DTC being detected.

DIAGNOSTIC AIDS
^ If the DTC B1349 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent and Poor Connections in Diagrams.
^ The following conditions may cause an intermittent malfunction to occur:
- An intermittent open in the GNDD circuit.
- An internal intermittent open in the BCM.

TEST DESCRIPTION

Steps 1-6:

The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks for an open in the ground circuit.
