Circuit Description
This circuit controls the front foglamp relay coil by grounding the circuit through the body control module (BCM). This condition is a code (history and current) that is set in the event of the front foglamp relay output is currently shorted to ground or open.
Conditions for Setting the DTC
All of the following conditions must be met:
| • | Ignition 1 is active. |
| • | The foglamp switch is off. |
| • | The front foglamp feedback is active. |
Action Taken When the DTC Sets
Stores DTC B2532 in the BCM memory.
Conditions for Clearing the DTC
| • | The BCM sleeps and reinitializes with the fault cleared. |
| • | All BCM history codes clear after 100 ignition cycles (from OFF to RUN) with no current codes active during the 100 ignition cycles. |
| • | Use the Scan Tool . |
Diagnostic Aids
| • | 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 disappear. |
Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This step determines if the front foglamp relay is malfunctioning.
-
This step determines if there is an open in CKT 1317 within the right side IP wiring harness junction block.
-
This step determines if a short to ground exists in CKT 1317 between the right side IP wiring harness junction block and the body control module (BCM).
-
This step determines if an open exists in CKT 1317 between the BCM and the right side IP wiring harness junction block.
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. | ||||
