B2527 CADILLAC Description
The Body Control Module (BCM) monitors the Front Fog Lamp Switch signal circuit in order to determine when the fog lamp relay is to be energized. When the BCM senses that the front fog lamp switch signal circuit is grounded momentarily by pressing the fog lamp switch, the BCM energizes the fog lamp relay by grounding the fog lamp relay control circuit. The code is set when the front fog lamp switch signal circuit is shorted to ground for approximately 15 seconds.
