B2532

DTC B2532

CIRCUIT DESCRIPTION
The body control module (BCM) controls the fog lamp relay. The BCM gets an input from the fog lamp switch circuit and then energizes the fog lamp relay by grounding the fog lamp relay coil control circuit. The BCM grounds the fog lamp relay coil control circuit if the following conditions exist:
- The ignition switch must be in the RUN position.
- The headlamp switch must be in the PARK or HEAD position.
- The headlamp dimmer switch must be in the LOW position.

CONDITIONS FOR RUNNING THE DTC
The BCM must not be commanding the fog lamp relay to energize.

CONDITIONS FOR SETTING THE DTC
- The BCM detects a short to ground or open in the fog lamp relay coil control circuit when the BCM is not trying to energize the fog lamp relay.
- The condition above must be present for more than 0.3 seconds.

ACTION TAKEN WHEN THE DTC SETS
The BCM stores DTC B2532 in memory.

CONDITIONS FOR CLEARING THE DTC
- A current DTC B2532 will clear if the BCM no longer detects a short to ground or open in the fog lamp relay coil control circuit.
- A history DTC B2532 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.

DIAGNOSTIC AIDS
- If the DTC B2532 is a history DTC, the fault may be intermittent.
- The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to ground or open in fog lamp relay coil control circuit.
- The fog lamp relay coil is intermittently shorted to ground or open internally.
- The BCM is intermittently shorted to ground or open internally.
