Precautions

Precautions for Discharge Headlight Service (If Equipped)

S5JB0A9200001

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 (Vehicle Equipped with Auto Leveling Headlight System)

S5JB0A9200002

• Be sure to read “Precautions for Electrical Circuit Service 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 auto leveling headlight system according to 
“Initialization of Auto Leveling Headlight System”.

General Description

Discharge Headlight Description (If Equipped)

S5JB0A9201001

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.

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 (2) and 
metal iodide 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.
