lto IPDM E/R terminals 38 and 59
lthrough grounds E21, E41 and E61.
FOG LAMP OPERATION
The front fog lamp switch is built into the combination switch. The lighting switch must be in the 1ST position,
2ND position or AUTO position (LOW beam is ON) and the front fog lamp switch must be ON for front fog lamp
operation.
With the front fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the front
fog lamp relay. The front fog lamp relay then directs power
lthrough 20A fuse (No. 56, located in IPDM E/R)
lthrough IPDM E/R terminal 50
lto front fog lamp LH terminal 1 and
lthrough IPDM E/R terminal 51
lto front fog lamp RH terminal 1.
Ground is supplied at all times
lto front fog lamp RH and LH terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front fog lamps illuminate.

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.
