Code B2530 Description

The front fog lamp relay is always supplied with battery voltage. The front fog lamp switch signal circuit is grounded momentarily by pressing the front fog lamp switch. The body control module (BCM) energizes the front fog lamp relay by applying ground to the front fog lamp relay control circuit. When the front fog lamp relay is energized, the relay switch contacts close, and battery voltage is applied through the fog lamp fuse to the front fog lamp control circuit which illuminates the front fog lamps. The Diagnostic Trouble Code (DTC) will be set when the BCM detects a problem with the front fog lamp relay control circuit.
