Schematic:

DTC PARAMETERS
^ Driver door unlock is requested
^ Circuit 694 shorted-to-ground.

DIAGNOSTIC AIDS
^ When a shorted-to-ground condition exists in circuit 694 and the BCM has been requested to activate the driver door unlock relay, the BCM will attempt to switch circuit 694 to battery voltage. High current flow will result and the BCM output will go into a protective state. The BCM output will not allow itself to be activated for as much as 3 minutes.
^ 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.
