FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationEKS00HX5
System DescriptionEKS00HX6
The front fog lamps are controlled by lighting switch inputs to the BCM (body control module). The lighting
switch must be in the 1ST or 2ND position with the high beams OFF before the BCM will request the IPDM E/
R (intelligent power distribution module engine room) to turn the front fog lamps on. The BCM requests the
front fog lamps over the CAN communication lines to the IPDM E/R. The CPU (central processing unit) of the
IPDM E/R controls the front fog lamp relay coil ground. When energized, the relay directs power to the front
fog lamps.
OUTLINE
Power is supplied at all times:

to front fog lamp relay (located in IPDM E/R),

to ignition relay (located in IPDM E/R),

through 15A fuse (No. 52, located in IPDM E/R) and

through 20A fuse (No. 53, located in IPDM E/R)

to CPU located in IPDM E/R,

through 40A fusible link (letter g , located in the fuse and fusible link box)

to BCM terminal 70,

through 10A fuse [No. 8, located in fuse block (J/B)]

to BCM terminal 57,

through 10A fuse [No. 13, located in fuse block (J/B)]

to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied:

to ignition relay (located in IPDM E/R),

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67

through grounds M57 and M61,

to IPDM E/R terminals 39 and 59

through grounds E15 and E24.

FRONT FOG LAMP
Revision: June 20062007 Versa
FOG LAMP OPERATION
The front fog lamp switch is built into the lighting switch. The lighting switch must be in 1ST position or 2ND
position and front fog lamp switch must be ON position for front fog lamp operation. The fog lamp will not oper-
ate with the high beam headlamps ON.
When the front fog lamp switch is in the ON position, the BCM sends a request, via the CAN communication
lines, to the CPU of the IPDM E/R to ground the coil side of the front fog lamp relay. The front fog lamp relay
then directs power

through 15A fuse (No. 56, located in IPDM E/R)

through IPDM E/R terminal 50

to front fog lamp LH terminal 1, and

through IPDM E/R terminal 51

to front fog lamp RH terminal 1.
Ground is supplied

to front fog lamp terminal 2,

through grounds E15 and E24.
With power and grounds supplied, front fog lamps illuminate.
