Igniter
Igniter generates high voltage needed to turn on the discharge headlight. It is charged with high voltage raised by the
ballast and it applies voltage pulse as high as about 20,000V to the tungsten electrode in the discharge headlight bulb.
After the discharge headlights light up, the ballast supplies voltage to bulbs.
Discharge headlight bulb
Discharge headlight bulb is used for the low beam. It does not have a filament but xenon gas (1), mercury (3) and
metal iodide (2) sealed in it. It lights up when its tungsten electrodes (4) apply high voltage to these contents.
Fail-safe function of discharge headlight
As the ballast has a fail-safe function which stops supply of the voltage to the igniter when it detects any of the
following condition.
• Ignition switch is set to “HEAD” position while igniter is not connected to discharge headlight bulb
• Discharge headlight does not light up even when lighting switch is set to “HEAD” position.
• Ballast detects a short in the circuit between discharge headlight bulb and ballast when lighting switch is at “HEAD”
position.
Headlight Auto Leveling System Description (If Equipped)S6RW0D9201002
Headlight Auto Leveling System adjusts the optical axis of the headlight automatically to be suitable for the varied
vehicle position while the headlights are lit. It consists of front height sensor (1), rear height sensor (2), headlight
leveling control module (3), headlight leveling actuator (4) and headlight leveling warning light (5).

With more passenger(s) or luggage in the vehicle, the vehicle position differs from that in such vehicle state with one
person and no load in the vehicle and angle of the headlight optical axis varies accordingly. This system automatically
adjusts the varied angle to maintain the optical axis properly.
Front and rear height sensors
Front height sensor (1) is installed to the front suspension frame (2) respectively and connected to the lower arm (4)
with the link (3). Also rear height sensor is installed to the rear floor center cross member (5) respectively and
connected to the rear axle (6) with the link (3). Each height sensor converts vertical movement of the lower arm into
the resistance value and outputs the detected change in the vehicle position as a voltage signal to the headlight
leveling control module.
Headlight leveling control module
Headlight leveling control module is installed at the inside of the glove box. It uses the headlight ON signal from the
lighting switch, vehicle speed signal from BCM and vehicle position signal from height sensors to calculate the angle
of the headlight optical axis to be corrected. Then it adjusts the optical axis angle of headlight based on the calculated
angle value by driving the headlight leveling actuator so that proper headlight aiming is obtained. Also, when any
abnormality is detected in the system, the headlight leveling control module makes the headlight leveling warning light
in the combination meter light up to warn the driver of an abnormality in the system.
Fail-safe function of headlight leveling control module
Headlight leveling control module has a fail-safe function which operates as follows.

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.
