System Description

EKS00FVG

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The light-
ing switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.
When the lighting switch is placed in the fog lamp position, the BCM (body control module) receives input sig-
nal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communi-
cated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication
lines. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When acti-
vated, this relay directs power to the front fog lamps.

OUTLINE

Power is supplied at all times

to ignition relay, located in the IPDM E/R, and

to front fog lamp relay, located in the IPDM E/R, and

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

to CPU of the IPDM E/R, and

through 50A fusible link (letter g , located in the fuse and fusible link box)

to BCM terminal 70.

When the ignition switch is in ON or START position, power is supplied

to ignition relay, located in the IPDM E/R, and

through 10A fuse [No. 1, located in the fuse block (J/B)]

to BCM terminal 38.

Ground is supplied

to BCM terminal 67

through grounds M57, M61 and M79, and

to IPDM E/R terminals 38 and 59

through grounds E9, E15 and E24.

FOG LAMP OPERATION

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.

FRONT FOG LAMP

2007 Pathfinder

With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power

through 20A fuse (No. 56, located in the 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 LH and RH terminal 2

through grounds E9, E15 and E24.

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

COMBINATION SWITCH READING FUNCTION

Refer to 

BCS-3, "COMBINATION SWITCH READING FUNCTION"

 .

EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the 2ND position (ON), the fog lamp switch is ON, and the
ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, then the fog lamps (and
headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
