CIRCUIT DESCRIPTION
The Body Control Module (BCM) receives ground from circuit 1550 used for door lock actuator motor operation.

CONDITIONS FOR SETTING THE DTC
^ The BCM detects an open in circuit 1550.
^ The BCM is open internally.
^ All conditions must be present for more than 0.3 seconds.

ACTION TAKEN WHEN THE DTC SETS
