HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -
• Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
- For vertical headlamp aiming, adjust headlamp until beam pattern is positioned per specified dimensions.

FRONT FOG LAMP
Component Parts and Harness Connector LocationINFOID:0000000001704397
System DescriptionINFOID:0000000001704398
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 the 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 switch. The lighting switch must be in 1ST position or 2ND
position and front fog lamp switch must be ON position for 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 position, 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
• through 15A fuse (No. 56, located in IPDM E/R)

OK >> Replace IPDM E/R. Refer to PG-26, "Removal and
Installation of IPDM E/R" .
NG >> Repair harness or connector.
Aiming AdjustmentINFOID:0000000001704409
The front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing
aiming adjustment, make sure of the following.
• Keep all tires inflated to correct pressure.
• Place vehicle on level surface.
• Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver’s position).
Coolant, engine oil filled up to correct level and full fuel tank, spare tire, jack and tools are properly stowed.
Adjust aiming in the vertical direction by turning the adjusting screw (A).
1. Set the distance (C) between the screen and the center of front
fog lamp lens (E) as shown.
2. Turn front fog lamps (1) to ON.
3. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone (A) is as shown.
NOTE:
When performing adjustment, if necessary, cover the headlamps
and opposite front fog lamp.
