REAR FOG LAMPPFP:26550
Component Parts and Harness Connector LocationEKS00P4G
System DescriptionEKS00P4H
The control of the rear fog lamps is dependent upon the position of the lighting switch. The lighting switch must
be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for rear fog lamp operation. When
the lighting switch is placed in the rear fog lamp position the BCM (body control module) receives input signal
requesting the rear fog lamps to illuminate.
