### All Door Unlock Circuit High

### Circuit Description

The 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.

The lock/unlock power application is limited by the BCM to 0.375 seconds to protect the lock motors.

### Conditions for Setting the DTC

• | All door unlock is not requested.

• | Circuit 194 is shorted to battery voltage.

• | Condition exists for 30 seconds.

### Diagnostic Aids

• | Inspect the wiring harness for damage. Check for broken or chafed insulation.

• | If a fault is suspected to be intermittent, wiggling the harness wiring may help in locating the fault.
