Component Parts and Harness Connector LocationINFOID:0000000003533332
System DescriptionINFOID:0000000003533333
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
requesting the headlamps (and tail lamps) illuminate. This input 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 controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
• to ignition relay, located in the IPDM E/R,
• to headlamp high relay, located in the IPDM E/R,
• to headlamp low relay, located in the IPDM E/R,
• through 20A fuse (No. 53, located in the IPDM E/R)
• to CPU of the IPDM E/R, and
• through 50A fusible link (letter f , located in the fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
• to ignition relay, located in the IPDM E/R, and
• through 10A fuse (No. 59, located in the fuse and relay box)

lamps turn off when lighting switch is in the 2ND position or AUTO position (Headlamp is "ON") and when light-
ing switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line.
OUTLINE
Power is supplied at all times
• to ignition relay, located in the IPDM E/R (intelligent power distribution module engine room),
• through 50A fusible link (letter f , located in the fuse and fusible link box)
• to BCM terminal 70,
• through 20A fuse (No. 53, located in the IPDM E/R)
• to CPU (central processing unit) of the IPDM E/R,
• through 10A fuse [No. 19, located in the fuse block (J/B)]
• to combination meter terminal 8, and
• through 10A fuse (No. 45, located in the IPDM E/R)
• to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied
• to ignition relay, located in the IPDM E/R,
• through 10A fuse (No. 59, located in the fuse and relay box)
• to BCM terminal 38, and
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• to combination meter terminal 24.
Ground is supplied
• to BCM terminal 67 and
• to combination meter terminal 17
• through grounds M57, M61 and M79.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the IPDM
E/R receives input requesting the daytime lights illuminate. This input is communicated across the CAN com-
munication lines. The CPU of the IPDM E/R controls the daytime light relay coil. When energized, this relay
directs power
• through daytime light relay terminal 3
• to front combination lamp LH terminal 2
• through front combination lamp LH terminal 6
• to IPDM E/R terminal 55
• through 10A fuse (No. 35, located in the IPDM E/R)
• through 10A fuse (No. 34, located in the IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 2
• through grounds E9, E15 and E24.
With power and ground supplied, the daytime lights illuminate. The high beam headlamps are now wired in
series and illuminate at a reduced intensity.

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 CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When acti-
vated, this relay directs power to the front fog lamps.
