HEADLAMP - XENON TYPE -
Revision: 2004 November 2004 FX35/FX45
With the ignition switch in the ON or START position, power is supplied
to ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM (body control module) terminal 38
through 10A fuse [No. 14, located in fuse block (J/B)]
to combination meter terminal 7.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM (body control module) terminal 11.
Ground is supplied
to BCM (body control module) terminals 49 and 52
through grounds M35, M45 and M85
to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60
through grounds E21, E50 and E51
to combination meter terminals 5, 6 and 15
through grounds M35, M45 and M85.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU in the
IPDM E/R controls the headlamp low relay coil, which when energized, directs power
to 15A fuse [No. 76, located in IPDM E/R]
through IPDM E/R terminal 20
to headlamp RH terminal 6
to 15A fuse [No. 86, located in IPDM E/R]
through IPDM E/R terminal 30
to headlamp LH terminal 6.
Ground is supplied
to headlamp RH terminal 7
through grounds E21, E50 and E51
to headlamp LH terminal 7
through grounds E21, E50 and E51.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input signal
requesting the headlamp high beams to illuminate. This input signal is communicated to the IPDM E/R across
the CAN communication lines. The CPU in the IPDM E/R controls the headlamp high relay coil and low relay
coil, which when energized, directs power
to 15A fuse [No. 76, located in IPDM E/R]
through IPDM E/R terminal 20
to headlamp RH terminal 6, and
to 15A fuse [No. 86, located in IPDM E/R]
through IPDM E/R terminal 30
to headlamp LH terminal 6
to 10A fuse [No. 72, located in IPDM E/R]
through IPDM E/R terminal 27
to headlamp RH terminal 5, and
to 10A fuse [No. 74, located in IPDM E/R]
through IPDM E/R terminal 28

DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationAKS007MZ
System DescriptionAKS007N0
DAYTIME LIGHT SYSTEM turns on Daytime Light Lamps while driving. Day Light Lamps are not turned on if
engine is activated with Parking Brake on. Take off Parking Brake to turn on Daytime Light Lamps. The lamps
turn off when Lighting Switch is in the 2ND position or AUTO position (Head Lamp is “ON”) and when Lighting
Switch is in the PASSING position. (Daytime Light Lamps are not turned off only by Parking Brake itself.)
An parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.

FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationAKS007O5
System DescriptionAKS007CI
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 central processing unit of the IPDM E/R controls the front fog lamp relay coil. When activated, this
relay directs power to the front fog lamps.

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.
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 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 E21, E50 and E51, and
to front fog lamp RH terminal 2
through grounds E21, E50 and E51.
With power and grounds 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.
CAN Communication System DescriptionAKS007CJ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS0080V
Refer to LAN-6, "CAN Communication Unit" .

System DescriptionAKS007DT
Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting
switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control
module) receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate.
This input signal is communicated 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 (intelligent power distribu-
tion module engine room) controls the tail lamp relay coil. This relay, when energized, directs power to the
parking, license plate, side marker and tail lamps, which then illuminate.
The current that flows by Rear combination lamp unit is controlled, and a tail lamp (LED) is made to turn on.
Power is supplied at all times
