Chart 5 - B3133 - All Door Unlock Circuit High

Diagnostic Chart 5:

Schematic:

Door locking/unlocking, by remote keyless entry (RKE) or driver/all door lock switches, is controlled through the body control module (BCM).

When an all other door unlock has been requested, the BCM switches circuit 194, to battery voltage. This energizes the door unlock relay which supplies power to the all passenger door lock motors. Grounding is achieved through the closed contacts of the door lock relay.

Lock/Unlock power application is limited by the BCM to .375 seconds to protect lock motors.

DTC Parameters
^ All door unlock is not requested.
^ Circuit 194 shorted-to-battery voltage
^ Condition exists for 30 seconds

Diagnostic AIDS
^ Inspect wiring harness for damage. Check for broken or chaffed insulation.
^ If fault is suspected to be intermittent, wiggling harness wiring may help in locating fault.
