Inspection of HVAC Control Module and Its CircuitS6RW0D7224029
HVAC control module and its circuits can be checked at HVAC control module wiring couplers by measuring voltage.
CAUTION!
HVAC control module can not be checked by itself. It is strictly prohibited to connect voltmeter to
HVAC control module with couplers disconnected from it.

Voltage Check
1) Remove HVAC control module referring to “HVAC Control Module Removal and Installation”.
2) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when ignition
switch is ON.

Precautions
Precautions for Discharge Headlight Service (If Equipped)S6RW0D9200001
WARNING!
• Do not touch igniter or ballast when lighting switch is at “HEAD” position to avoid possible electric
shock.
• Do not measure voltage or resistance with tester connected to output connector of ballast or igniter
to avoid possible electric shock.
• Do not perform work where exposed to water including rain or with wet hands to avoid possible
electric shock.
• Disassembling igniter or ballast is strictly prohibited as it may cause an electric shock.
• Before inspecting or repairing discharge headlight or its peripheral parts, make sure that lighting
switch is at OFF position and battery is disconnected at negative terminal to avoid possible
electrical shock.
• Do not set lighting switch to “HEAD” position with connector disconnected or any part removed to
avoid possible electric shock.
• Do not touch glass surface of headlight bulb. Oil or grease attached on it may not only make bulb
service life shorter but also cause bulb to burst when lighting switch is turned on.
• Mercury, metal iodide and xenon gas are sealed in discharge headlight bulb. Be sure to dispose of
used discharge headlight bulb properly according to applicable rules or regulations.

Precautions in Diagnosing Troubles (Headlight Auto Leveling System)S6RW0D9200002
• Be sure to read “Air Bag Warning in Section 00” before inspection and observe what is written there.
• Replacement of height sensor and headlight leveling control module. When height sensor and/or headlight leveling
control module is replaced with new one, perform initialization of headlight auto leveling system according to
“Initialization of Headlight Auto Leveling System”.
General Description
Discharge Headlight Description (If Equipped)S6RW0D9201001
Discharge headlight provides more brightness and consumes less electricity as compared with the conventional
halogen headlight. It consists of a ballast (1), igniter (2) and discharge headlight bulb (3).
Ballast
Ballast makes the voltage from the battery rise and converts the current from DC to AC. It also outputs high voltage to
the igniter when the headlight is turned on and supplies to discharge headlight bulb with necessary voltage for
continuous lighting while it is lit.

I6RW0C920001-01

Downloaded from www.Manualslib.com manuals search engine Lighting Systems: 9B-2
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).
