FRONT FOG LAMP
With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power
• through 20A fuse (No. 56, located in the IPDM E/R)
• through IPDM E/R terminal 50
• to front turn/fog lamp LH terminal 1, and
• through IPDM E/R terminal 51
• to front turn/fog lamp RH terminal 1.
Ground is supplied
• to front turn/fog lamp LH and RH terminal 3
• through grounds E9, E15 and E24.
With power and ground supplied, the front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "System Description" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the fog lamp switch is ON, and the
ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, then the fog lamps (and
headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

Aiming AdjustmentINFOID:0000000003533400
The 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 ground.
• See 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 seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Access adjustment screw from underneath front bumper. 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. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 200 mm (7.9 in) below the height of
the fog lamp centers as shown.
• When performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.
