REAR FOG LAMP
REAR FOG LAMP OPERATION
The lighting switch must be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for rear fog
lamp operation.
With the rear fog lamp switch in the ON position, the BCM directs power
lthrough BCM terminal 49
lto rear combination lamp LH terminal 6 (LHD models)
lto rear combination lamp RH terminal 6 (RHD models).
Ground is supplied
lto rear combination lamp RH and LH terminals 3
lthrough grounds E21, E41 and E61.
With power and ground supplied, the rear fog lamps illuminate.
