High Beam Relay Circuit Shorted Hi
When Monitored and Set Condition: HIGH BEAM 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 High beam relay and excessive current is sinked into the BCM.
Possible Causes are:
- HI BEAM RELAY
- HIGH BEAM RELAY CONTROL CIRCUIT SHORTED TO B (+)
- BCM HIGH BEAM CONTROL SHORT TO BATTERY
- Install a known-good relay in place of the High Beam relay. Does the system now operate correctly? If yes, replace the High Beam relay. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, go to next step.
- Remove the High Beam 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 High Beam Relay control circuit cavity No. 86 to ground at the Junction Block. Was the voltage greater 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.
