HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R via the CAN communication lines. The CPU located
in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

through 15A fuse (No. 41, located in IPDM E/R)

through IPDM E/R terminal 54

to daytime light relay 2 terminals 1 and 5 (energizing the relay),

through daytime light relay 2 terminal 3

to front combination lamp RH terminal 3, and

through 15A fuse (No. 40, located in IPDM E/R)

through IPDM E/R terminal 52

to front combination lamp LH terminal 3.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24,

to headlamp RH terminal 2 via

daytime light relay 1 terminals 3 and 4

through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives input
signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and
also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination
meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay
coil, which when energized, directs power

through 10A fuse (No. 34, located in IPDM E/R)

through IPDM E/R terminal 56

to front combination lamp RH terminal 1, and

through 10A fuse (No. 35, located in IPDM E/R)

through IPDM E/R terminal 55

to front combination lamp LH terminal 1.

through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power

from daytime light relay 1 terminal 3

to front combination lamp RH terminal 2,

through front combination lamp RH high beam terminal 1

to IPDM E/R terminal 56,

through 10A fuse (No. 34, located in IPDM E/R) and

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

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.
