HEADLAMP - XENON TYPE -
Revision: 2006 July 2007 FX35/FX45
HEADLAMP - XENON TYPE -PFP:26010
Component Parts and Harness Connector LocationNKS002V5
System DescriptionNKS002V6
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) through the CAN communication lines. The CPU (central
processing unit) located in 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

to headlamp low relay, located in IPDM E/R and

to ignition relay, located in IPDM E/R, from battery direct,

through 10A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU located in IPDM E/R,

through 50A fusible link (letter M, located in fuse, fusible link and relay box)

to BCM terminal 55,

through 15A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42,

through 10A fuse [No. 19, located in fuse block (J/B)]

to combination meter terminal 8.
