This circuit controls the front foglamp relay coil by grounding the circuit through the body control module (BCM). This condition is a fault code (history and current) that is set if the front foglamp relay output is shorted to ground.
All of the following conditions must be met:
• | Ignition 1 is active. |
• | The front foglamp output is shorted to ground for 5 seconds. |
• | The foglamp switch is off. |
Stores DTC B2532 in the BCM memory.
• | The BCM sleeps and reinitializes with the fault cleared. |
• | All BCM history codes clear after 100 ignition cycles (from OFF to ON) with no current codes active during the 100 ignition cycles. |
• | Use the Scan Tool . |
• | The fog lamps only illuminate under the following conditions: |
- | The parklamps are ON. |
- | The fog lamp switch is actuated. |
• | If the DTC is a history DTC, the problem may be intermittent. Perform the tests shown while wiggling the wiring and connectors. This action may cause the malfunction to appear. |
The numbers below refer to the step numbers on the diagnostic table.
This step determines if the front foglamp relay is receiving voltage from the FOGLPS fuse.
This step determines if a short to ground exists in CKT 1317 within the right IP junction block.
This step determines if the foglamp relay is operating properly.
This step determines if a short to ground exists in CKT 1317 between the right IP junction block and the body control module (BCM).
Step | Action | Value(s) | Yes | No |
---|---|---|---|---|
Important: A short to ground will cause an open fuse(s). Before performing this diagnostic procedure, inspect the fuse(s) for an open. | ||||
