Fog Lamp Operation

WARNING: This page is about a different car, the 2004 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation.

With the fog lamp switch in the ON position, the CPU (central processing unit) of the IPDM E/R (intelligent power distribution module engine room) grounds the coil side of the fog lamp relay. The fog lamp relay then directs power

through IPDM E/R terminal 37
to front fog lamp LH terminal 1
through IPDM E/R terminal 36
to front fog lamp RH terminal 1.

Ground is supplied

to front fog lamp LH terminal 2
through grounds E13, E26 and E28
to front fog lamp RH terminal 2
through grounds E13, E26 and E28.

With power and grounds supplied, the front fog lamps illuminate.
