Component Parts and Harness Connector LocationINFOID:0000000005394896
System DescriptionINFOID:0000000005394897
Headlamp operation is controlled by the BCM (body c ontrol module) based on inputs from the combination
switch (lighting switch). When the lighting switch is pl aced in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The request is then communicated to the IPDM E/R
(intelligent power distribution module engine room) vi a the CAN communication lines. The CPU (central pro-
cessing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils.
These relays direct power to the respective headlamps , which then illuminate.  When the headlamp switch is
OFF or in the 1ST position (parking lamps ON), the  parking brake is released and the engine is running, the
IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light relay 1 to actuate the
daytime light function.

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

PARKING, LICENSE PLATE AND TAIL LAMPS

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
