NOTE
Front fog lights light up only when headlight
switch is in HEADLIGHT position (low or high
beams) or SMALL position. Front fog lights
turn OFF automatically when headlight
switch is turned to OFF position. If front fog
light switch holds ON position, front fog
lights turn ON automatically when headlight
switch is tuned to HEADLIGHT position (low
or high beams) or SMALL position again.

Check for continuity between terminals at each switch
position. If check result is not as specified, replace
switch.
Front Fog Light Aiming Adjustment with Screen
(If Equipped)
S6RW0D9206018
Basic Aiming
NOTE
• Unless otherwise obligated by local
regulations, adjust front fog light aiming
according to the following procedure.
• An example in case that the light-to-wall
distance 10 m is shown in the illustration.
The beam descending distance “H” is
calculated when “a” is 10 m with the
specification angle “b” (1.14°).

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall
(screen) (1) ahead of front fog light surface.
Distance between screen and front fog light
“a”: 10 m (32.8 ft.)
• Adjust air pressure of all tired to the specified
value respectively.
• Bounce vehicle body up and down by hand to
stabilize suspension.
• Carry out aiming with a driver aboard.

2) Check to see if hot spot (high intensity zone) of each
front fog light axis falls as shown in the figure.
NOTE
If the fog lights interfere each other and make
it hard to see the cut line clearly, cover the
fog light on one side. This helps to make
aiming adjustment easier.

Hot spot specification
Angle “b”: 1.14° (Specification)
Calculated distance “H”: Approx. 199 mm (7.83
in.)
3) If it is not set properly, align front fog light to
specification by rotating aiming gear.
Rear Fog Light Switch Inspection (If Equipped)S6RW0D9206021
NOTE
• Rear fog light switch can be turned to ON
position only when headlight switch is
turned to HEADLIGHT position (low or high
beams).
• Rear fog light switch turns OFF
automatically when headlight switch is
turned to OFF position.

Check for continuity between terminals at each switch
position.
If check result is not as specified, replace switch.

Height Sensor Removal and Installation (If
Equipped)
S6RW0D9206027
Removal
CAUTION!
• Do not remove bracket (4) and link (3) from
height sensor (2). Removal will spoil its
original function. If faulty condition is
found, replace it with new one in a set.
• If height sensor was dropped from a height
of 30 cm (0.9 ft) or more, replace it with
new one.

1) Disconnect negative (–) cable at battery.
2) Disconnect height sensor connector (1) from height
sensor (2).
3) Remove front and rear height sensor (2) with its
bracket (4) from suspension frame (6) or rear floor
center cross member (7) and lower arm (5).Installation
For installation, reverse removal procedure noting the
following.
• Check that bracket and link of height sensor are not
deformed.
• Tighten height sensor bolts and nuts to specified
torque.
Tightening torque
Height sensor bolt (a): 5.5 N·m (0.6 kgf-m, 4.0 lb-ft)
Height sensor nut (b): 13 N·m (1.3 kgf-m, 9.5 lb-ft)
• Connect connector securely.
• After installation, initialize headlight auto leveling
system referring to “Initialization of Headlight Auto
Leveling System”.

• For front height sensor
Between “G14-20” and “G14-22” terminals of
headlight leveling control module.
• For rear height sensor
Between “G14-19” and “G14-21” terminals of
headlight leveling control module.
If check result is not as specified, perform
inspections of power supply, ground and signal
circuits of front or rear height sensor which is
described under “Inspection of Headlight Leveling
Control Module and Its Circuit (Headlight Auto
Leveling System)”. If circuits are OK, replace
height sensor.
