The rear window defogger system is controlled by BCM (body control module) and IPDM E/R (intelligent
power distribution module engine room).
The rear window defogger only operates for approximately 15 minutes.
Power is supplied at all times

through 15A fuses (No. 46 and 47, located in the IPDM E/R)

to rear window defogger relay

through 10A fuse [No. 5 (with heated mirrors), located in the fuse block (J/B)]

to heated mirror relay terminal 3

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

to BCM terminal 70.
With the ignition switch turned to ON or START position, power is supplied

through ignition relay

to rear window defogger relay (located in the IPDM E/R)

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

to BCM terminal 38.

to front air control terminal 8

through body grounds M57 and M61

to IPDM E/R terminals 39 and 59

through body grounds E15 and E24.
When front air control (rear window defogger switch) is turned to ON, ground is supplied

to BCM terminal 9

through front air control terminal 3

through front air control terminal 8

through body grounds M57 and M61.
Then rear window defogger switch is illuminated.
Then BCM recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to IPDM E/R via CAN communication (CAN-H, CAN-L).
When IPDM E/R receives rear window defogger switch signals, ground is supplied

to rear window defogger relay (located in the IPDM E/R)

through IPDM E/R terminals 39 and 59

through body grounds E15 and E24
Then rear window defogger relay is energized.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON (with heated mirrors), power is supplied

through heated mirror relay terminal 5

to door mirror (LH and RH) terminal 1.
Door mirror (LH and RH) is grounded through body grounds M57 and M61.
With power and ground supplied, rear window defogger filaments heat and defog the rear window and door
mirror filaments heat and defog the mirrors.

HEADLAMP (FOR USA)PFP:26010
Component Parts and Harness Connector LocationEKS00HVB
System DescriptionEKS00HVC
Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination
switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The BCM sends a signal, via the CAN communica-
tion lines, to the IPDM E/R (intelligent power distribution module engine room) requesting the headlamps be
turned ON. The CPU (central processing unit) located in the IPDM E/R controls ground for the headlamp high
and headlamp low relay coils. These relays direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times

to headlamp high relay RH and LH (located in IPDM E/R),

to headlamp low 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 fuse and fusible link block)

to BCM terminal 70,

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

to BCM terminal 57, and

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

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

to BCM terminal 38,

through 10A fuse [No. 3, located in fuse block (J/B)]

to combination meter terminal 28.

HEADLAMP (FOR USA)
Revision: June 20062007 Versa
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

to combination meter terminals 21, 22 and 23

through grounds M57 and M61, and

to IPDM E/R terminals 39 and 59

through grounds E15 and E24.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illumi-
nate. The BCM then sends a signal, via the CAN communication lines, to the IPDM E/R requesting the low
beam headlamps be turned ON. The CPU located in the IPDM E/R controls ground to 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 headlamp RH terminal 3, and

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

through IPDM E/R terminal 52

to headlamp LH terminal 3.
Ground is supplied

to headlamp RH and LH terminals 2

through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives an 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 then communicated to the IPDM E/R and the combination
meter via the CAN communication. The CPU located in the IPDM E/R controls the headlamp high relays (LH
and RH), which when energized, directs power

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

through IPDM E/R terminal 56

to headlamp RH terminal 1, and

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

through IPDM E/R terminal 55

to headlamp LH terminal 1.
Ground is supplied

to headlamp RH and LH terminal 2

through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal, via the CAN communication lines, to the combination meter requesting the high
beam indicator lamp be turned ON.
