HEADLAMP - XENON TYPE -PFP:26010
Component Parts and Harness Connector LocationAKS007M9
System DescriptionAKS007MA
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) across the CAN communication lines. The central pro-
cessing unit of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays, when
energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.
OUTLINE
Power is supplied at all times
to headlamp high relay [located in IPDM E/R (intelligent power distribution module engine room)]

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
to headlamp LH terminal 5.

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.
