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.

Interior Light Symptom DiagnosisS6RW0D9204011
NOTE
• Use of SUZUKI scan tool makes it easy to check whether a faulty condition is on the input side or
output side of BCM. For checking procedure, refer to “Diagnosis Using Output Test Function of
SUZUKI Scan Tool” under “Scan Tool Data in Section 10B”.
• Check each part in the order from the top of the following list.

DRL Operation Inspection (If Equipped)S6RW0D9204012
1) Confirm that lighting switch is in OFF position.
2) Confirm that dimmer and passing switch is in low beam position.
3) Check DRL for operation as follows.
a) Turn ignition switch to ON position and check headlights remain OFF.
b) Start engine and run it at idle speed. Check headlights turn ON at low beam.
c) Switch dimmer and passing switch to high beam position and check headlights remain turning ON at low
beam.
4) If check result is not as satisfied, go to “Inspection of DRL Controller and Its Circuits (If Equipped)”.
Inspection of DRL Controller and Its Circuits (If Equipped)S6RW0D9204013
1) Confirm that lighting switch is in good condition referring to “Headlight Switch (in Lighting Switch) Inspection”.
2) Confirm that oil pressure switch is in good condition referring to “Oil Pressure Switch Inspection in Section 9C”.
