Headlight Model)
S6RW0D9206024
WARNING!
Be sure to read “Precautions for Discharge
Headlight Service (If Equipped)” carefully
before working. Neglecting them may result
in personal injury.

Removal
1) Remove ballast referring to “Ballast Removal and
Installation (Discharge Headlight Model)”.
2) Remove cover (1) from headlight housing by turning
it counterclockwise.
3) Remove igniter (2) from discharge headlight bulb by
turning it counterclockwise.
4) After disconnecting ground wire (3), pull out igniter
(2) from headlight housing.Installation
Reverse removal procedure noting the following.
• Connect connectors securely.
• After installation, be sure to inspect and adjust aiming
referring to “Headlight Aiming Adjustment with
Screen”.
Headlight Aiming Adjustment with ScreenS6RW0D9206003
NOTE
• Unless otherwise obligated by local regulations, adjust headlight aiming according to the following
procedure.
• After replacing headlight housing, be sure to adjust aiming.
• When inspecting and adjusting headlight with leveling system, make sure to set the leveling switch
to “0” position with ignition switch turned ON.

1) Make sure the following items.
• Place vehicle on a flat surface in front of blank wall (screen) (1) ahead of headlight surface.
Distance “a”
10 m (32.8 ft.)
• Adjust air pressure of all tires to the specified value respectively.
• Bounce vehicle body up and down by hand to stabilize suspension.
• Carry out aiming with a driver aboard.
Driver’s weight
75 kg (165 lb)
2) Check to see if hot spot (high intensity zone) of each low beam axis falls as shown in figure.
NOTE
If the headlights interfere each other and make it hard to see the cut line clearly, cover the headlight on
one side. This helps to make aiming adjustment easier.

Hot spot specification
Angle “b”: 0.75° (Specification)
Calculated distance “H”: Approx. 130 mm (5.15 in.)
3) Align headlight aiming to specification by adjusting aiming gear if it is not set properly.

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)

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.

NOTE
This thermometer indicates the ambient temperature in the under side of front bumper member. Under
any one of the following listed conditions, however, even when the ambient temperature goes up, the
thermometer display does not rise so as to correct the rise of the ambient temperature caused by the
radiant heat of the engine. When the ambient temperature drops, the thermometer reading follows the
change in the temperature.
Be sure to bear this in mind when diagnosing trouble.
• The vehicle speed is 30 km/h (18 mph) or lower.
• Vehicle speed signal is faulty.
• The ignition switch is turned on again within 2 hours.
