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 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,

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85.
HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R across 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. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6.
Ground is supplied

to front combination lamp RH terminal 7

through grounds E21, E50 and E51,

to front combination lamp 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 the 2ND position and placed in the 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 located in the IPDM E/R controls the headlamp high relay coil
and low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6,

through 10A fuse (No. 72, located in IPDM E/R)
