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.

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, the illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

STEERING WHEEL
CHECKING FRONT WHEEL TURNING ANGLE
When checking front wheel turning angle, refer to FSU-6, "Front Wheel Alignment" .
Removal and InstallationINFOID:0000000003532825
REMOVAL
1. Set the front wheels in the straight-ahead position.
2. Remove the driver air bag module. Refer to SRS-35, "
Removal and Installation".
3. Disconnect steering wheel switches.
4. Remove the steering wheel center nut.
5. Remove the steering wheel using Tools.
CAUTION:
Place a piece of tape across the spiral cable so it will not be
rotated out of position.
6. Inspect the steering wheel near the puller holes for damage. If
damaged, replace the steering wheel.
• Remove steering wheel rear cover and steering wheel
switches, if required.
INSTALLATION
Installation is in the reverse order of removal.
• Align spiral cable correctly when installing steering wheel. Make
sure that the spiral cable is in the neutral position. The neutral
position is detected by turning left 2.5 revolutions from the right
end position and ending with the knob at the top.
• If equipped with VDC, refer to BRC-54, "
Adjustment of Steering
Angle Sensor Neutral Position" for steering angle sensor adjust-
ment.
• After the work is completed, perform self-diagnosis to make sure
no malfunction is detected. Refer to SRS-20, "
SRS Operation
Check".
• Tighten steering wheel center nut to specification. Refer to PS-10,
"Removal and Installation".
CAUTION:
• The spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
• With the steering linkage disconnected, the cable may snap
by turning the steering wheel beyond the limited number of
turns. The spiral cable can be turned counterclockwise about
2.5 turns from the neutral position.Tool number A: J-1859-A

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Work FlowINFOID:0000000003533092
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer comments; refer to RF-8, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed description or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
• Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions. Hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
• Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
• Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
• Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
• Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often drought on by activity.
• Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge
as acceptable may be irritating to the customer.
• Weather conditions, especially humidity and temperature, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
