Fog Lamp Relay Circuit Shorted Hi

When Monitored: Ignition in run position.

Set Condition: The BCM detects excessive current on the fog lamp relay control circuit.

Possible Causes are:

• FOG LAMP RELAY
• FOG LAMP RELAY CONTROL SHORT TO B (+)
• BCM INTERNAL DEFECT FOG LAMP CONTROL SHORT TO BATTERY

1. Install a known-good relay in place of the Fog Lamp Relay. Does the system operate correctly? If yes, replace the Fog Lamp Relay. Perform BODY VERIFICATION TEST VER 1  under VERIFICATION TESTS. If no, go to next step.
2. Remove the Fog Lamp Relay from the Junction Block. Turn ignition off. Remove the Body Control Module from the Junction Block. Turn ignition on. Measure voltage of the Fog Lamp Relay control circuit at the Junction Block to ground. Is the voltage more than 1 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.
