Park Lamp Relay Circuit Shorted Hi
When Monitored and Set Condition: PARK LAMP RELAY CIRCUIT SHORTED HI
When Monitored: Ignition in RUN and IOD fuse/connector installed.
Set Condition: This condition is set when the BCM is trying to activate the park relay and excessive current is detected on the control circuit.
Possible Causes are:
- PARK LAMP RELAY
- BCM PARK LAMP CONTROL SHORT TO BATTERY
- PARK LAMP RELAY CONTROL SHORT TO B (+)
- Install a known-good relay in place of the Park Lamp relay. Does the system now operate correctly? If yes, replace the Park Lamp relay. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, go to next step.
- Remove the park lamp relay from the Junction Block. Turn ignition off. Remove the Body Control Module from the Junction Block. Turn ignition on. Using a voltmeter measure the Park Lamp Relay control circuit cavity No. 86 to ground at the Junction Block. Was the voltage more than one volt? If yes, replace the junction block. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, replace the Body Control Module. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
