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”.

Height Sensor and Its Circuit Inspection (If
Equipped)
S6RW0D9206028
1) Remove front or rear height sensor from vehicle
referring to “Height Sensor Removal and Installation
(If Equipped)”.
2) Connect connector to height sensor.
3) Vary position of height sensor link (1) and measure
voltage between terminals of headlight leveling
control module (4) as described below.
• 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.
Height sensor output voltage
Full bound position (2): about 0.5 V
Full rebound position (3): about 4.5 V
Headlight Leveling Control Module Removal
and Installation (If Equipped)
S6RW0D9206029
Removal
1) Disconnect negative (–) cable at battery.
2) Remove glove box.
3) Disconnect connector (1) from headlight leveling
control module (2).
4) Remove headlight leveling control module with its
bracket from steering support member (3).
Installation
For installation, reverse removal procedure noting the
following.
• Connect connector securely.
• After replacing headlight leveling control module with
new one, initialize headlight auto leveling system
referring to “Initialization of Headlight Auto Leveling
System”.
Initialization of Headlight Auto Leveling SystemS6RW0D9206030
Initialization of the headlight auto leveling system is to
make the headlight leveling control module learn signals
which are fed from the height sensors when the vehicle
is at the standard height. Standard height means the
height of the vehicle with a driver but without load in it.
Initialization of the headlight auto leveling system is
required when any of the following works has been
performed.
• Replacement of headlight leveling control module
• Removal of front and/or rear height sensor link from
lower arm
• Removal of front and/or rear height sensor from
suspension frame
• Replacement of front and/or rear height sensor

Without initialization of the headlight auto leveling
system, it is not possible to obtain its proper function.
Also, if the headlight auto leveling system is not
initialized after replacing the headlight leveling control
module, the headlight leveling warning light in the
combination meter flashes.
1) Observe the following instructions.
• Park vehicle on level ground.
• Adjust air pressure of all tires to the specified
value respectively.
• Bounce vehicle body up and down by hand to
stabilize suspension.
2) Turn ignition switch to ON position.
3) Perform “Headlight Leveling Warning Light Check”.
4) Connect service wire (2) to terminals of diagnosis
connector (1).
5) Perform Steps a) through b) described blow within
20 seconds after Step 4).
a) Turn lighting switch (3) to “HEAD” position and
then turn lighting switch to OFF position.
b) Repeat Step a) 2 times.
6) Confirm that headlight leveling warning light flashes
3 times and turns off, which indicates that system
initialization was completed properly. If it does not
turn off after flashing 3 times, it means initialization
was not successful. In such case, turn off ignition
switch and perform Steps 1) to 6) again.Auto-On Headlight Sensor Inspection (If
Equipped)
S6RW0D9206031
1) Disconnect negative (–) cable at battery.
2) Remove auto-on headlight sensor (1) located on the
passenger side of the dashboard (2). Be careful not
to damage the sensor (1) and dashboard by using
rag (3).
3) Measure voltage between white wire terminal and
black wire terminal at the following condition.
If measured voltage is out of specification, replace
sensor.
