Headlight leveling actuator
Headlight leveling actuator is (1) located in the headlight housing (2). It moves the reflector (3) in the headlight housing
according to the drive signal from the headlight leveling control module so as to adjust the optical axis of the headlight
to the angle calculated by the headlight leveling control module.
Auto-On Headlight System Description (If Equipped)S6RW0D9201003
The auto-on headlight is controlled by auto-on headlight controller (1) and works as follows.Under such conditions as
the ignition switch turned ON and the lighting switch (2) turned to the “AUTO” position, when illuminance to the auto-on
headlight sensor (3) becomes lower than the specified value, the headlights and clearance lights are turned ON by
auto-on headlight controller. On the other hand, when illuminance to the auto-on headlight sensor becomes higher
than the specified value under the same conditions, the headlights and clearance lights are turned OFF by auto-on
headlight controller.Voltage supplied to height sensor is lower
than 4.6VStops headlight leveling actuator operation. ON
Signal voltage from height sensor is higher
than 4.75V or lower than 0.25VStops headlight leveling actuator operation. ON
Abnormality in headlight leveling control
module is detectedResets microcomputer in headlight leveling
control module.ON
Correction value calculated by headlight
leveling control module exceeds operation
range of headlight leveling actuatorDrives headlight leveling actuator within its
operation range.OFF Detecting condition Fail-safe operation Warning light

Diagnostic Information and Procedures
Self-Diagnosis Function for Headlight Auto Leveling SystemS6RW0D9204014
The headlight leveling control module has self-diagnosis function to monitor the system components and circuits while
the headlight auto leveling system is at work. When the headlight leveling control module detects an abnormality in the
system, the headlight leveling warning light in the combination meter turns ON. However, the headlight leveling control
module does not have a function to indicate location of such abnormality.

Headlight Leveling Warning Light CheckS6RW0D9204015
1) Turn ignition switch to ON position.
2) Check that headlight leveling warning light (1) lights for about 2 seconds and then goes OFF. If the headlight
leveling warning light lights up again 10 seconds after it turned off, go to “Headlight Auto Leveling System
Symptom Diagnosis (If Equipped)”. If headlight leveling warning light flashes, go to “Initialization of Headlight Auto
Leveling System”.

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.
