1.CHECK COMBINATION SWITCH INPUT SIGNAL
1. Select “BCM” on CONSULT-II. Select “HEAD LAMP” on
“SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
3. Make sure that “LIGHT SW 1ST”, “HEADLAMP SW 1” and
“HEADLAMP SW 2” turns ON-OFF linked with operation of light-
ing switch.
OK or NG
OK >> GO TO 2.
NG >> Check combination switch (lighting switch). Refer toLT- 11 8 , "
Combination Switch Inspection".

FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationEKS00P3Y
System DescriptionEKS00P3Z
The control of the front fog lamps is dependent upon the position of the combination switch (lighting switch).
The lighting switch must be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for front
fog lamp operation. When the lighting switch is placed in the front fog lamp position, the BCM (body control
module) receives input signal requesting the front fog lamps to illuminate. When the headlamps are illumi-
nated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication. The CPU (central processing unit) of the IPDM E/R controls the front fog
lamp relay coil. When activated, this relay directs power to the front fog lamps.

Aiming AdjustmentEKS00P4D
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
lKeep all tires inflated to correct pressure.
lPlace vehicle on level surface.
lSee that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver's seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Use a Phillips screwdriver to adjust. Turn screw clockwise to raise
pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Remove front portion of fender protector(s) for adjusting screw
access. Refer toEI-22, "
Removal and Installation of Front
Fender Protector".
4. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown.
lWhen performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.

Precautions for Liquid GasketEBS01E52
LIQUID GASKET APPLICATION PROCEDURE
1. Remove the old liquid gasket adhering to the liquid gasket application surface and the mating surface.
lRemove the liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser [SST].
Use Genuine Liquid Gasket or equivalent.
lWithin five minutes of liquid gasket application, install the mating
component.
lIf the liquid gasket protrudes, wipe it off immediately.
lDo not retighten mounting bolts and nuts after the installation.
lAfter 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
