HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM re ceives an input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R via 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. 41, located in IPDM E/R)
• through IPDM E/R terminal 54
• to daytime light relay 2 terminals 1 and 5 (energizing the relay),
• through daytime light relay 2 terminal 3
• to front combination lamp RH terminal 3, and
• through 15A fuse (No. 40, located in IPDM E/R)
• through IPDM E/R terminal 52
• to front combination lamp LH terminal 3.
Ground is supplied
• to front combination lamp LH terminal 2
• through grounds E15 and E24,
• to headlamp RH terminal 2 via
• daytime light relay 1 terminals 3 and 4
• through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam s witch in the HIGH position, the BCM receives input
signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and
also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination
meter via the CAN communication lines. The CPU locat ed in the IPDM E/R controls the headlamp high relay
coil, which when energized, directs power
• through 10A fuse (No. 34, located in IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 1, and
• through 10A fuse (No. 35, located in IPDM E/R)
• through IPDM E/R terminal 55
• to front combination lamp LH terminal 1.
Ground is supplied
• to front combination lamp LH terminal 2
• through grounds E15 and E24, and
• to front combination lamp RH terminal 2 via
• daytime light relay 1 terminals 3 and 4
• through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power
• from daytime light relay 1 terminal 3
• to front combination lamp RH terminal 2,
• through front combination lamp RH high beam terminal 1

FRONT FOG LAMP
FRONT FOG LAMP
Component Parts and Harness Connector LocationINFOID:0000000005394912
System DescriptionINFOID:0000000005394913
The front fog lamps are controlled by lighting switch inputs to the BCM (body control module). The lighting
switch must be in the 1ST or 2ND position with t he high beams OFF before the BCM will request the IPDM E/
R (intelligent power distribution module engine room) to turn the front fog lamps on. The BCM requests the
front fog lamps over the CAN communication lines to the IPDM E/R. The CPU (central processing unit) of the
IPDM E/R controls the front fog lamp relay coil ground. When energized, the relay directs power to the front
fog lamps.
OUTLINE
Power is supplied at all times:
• to front fog lamp relay (located in IPDM E/R),
• to ignition relay (located in IPDM E/R),
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R,
• through 40A fusible link (letter g , located in the fuse and fusible link box)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57,
• through 10A fuse [No. 13, located in fuse block (J/B)]
• to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied:
• to ignition relay (located in IPDM E/R),
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M57 and M61,
• to IPDM E/R terminals 39 and 59
• through grounds E15 and E24.
FOG LAMP OPERATION
The front fog lamp switch is built into the lighting s witch. The lighting switch must be in 1ST position or 2ND
position and front fog lamp switch must be ON position fo r front fog lamp operation. The fog lamp will not oper-
ate with the high beam headlamps ON.
When the front fog lamp switch is in the ON positi on, the BCM sends a request, via the CAN communication
lines, to the CPU of the IPDM E/R to ground the coil side of the front fog lamp relay. The front fog lamp relay
then directs power

System DescriptionINFOID:0000000005394964
The control of the parking, license plate and tail lamp operation is dependent upon the position of lighting
switch. When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input
signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) located in the IPDM E/R contro ls the tail lamp relay coil. This relay, when energized,
directs power to parking, license plate and tail lamps, which then illuminate.
Power is supplied at all times
• to ignition relay located in IPDM E/R,
• to tail lamp relay located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to the CPU located in the IPDM E/R,
• through 40A fusible link (letter g , located in fuse and fusible link block)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)],
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38,
• to ignition relay located in IPDM E/R and
• through the ignition relay
• to the CPU of the IPDM E/R.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M20 and M61,
• to IPDM E/R terminals 59 and 39
• through grounds E15 and E24.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND positi on, the BCM receives an input signal requesting parking,
license plate and tail lamps to illuminate. This input si gnal is communicated to the IPDM E/R via the CAN com-
munication lines. The CPU, located in the IPDM E/R, c ontrols the tail lamp relay coil. When energized, the tail
lamp relay directs power
• through 10A fuse (No. 37, located in IPDM E/R),
• through IPDM E/R terminal 26
• to front combination lamp LH terminal 6, and
• through IPDM E/R terminal 27
