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.

S6RW0D9606014
NOTE
For keyless start model, perform
“Replacement of Remote Controller Battery
in Section 10E” instead of “Replacement of
Transmitter Battery (Other than Keyless Start
Model)”.

If transmitter becomes unreliable, replace transmitter
battery as follows.
1) Remove screw (1) and transmitter cover (2).
2) Remove transmitter (3) from transmitter holder (4).
CAUTION!
Use care not to allow grease or dirt to be
attached on the printed circuit board and the
battery.

3) With tip of flat blade screwdriver put in slot of
transmitter, pry it open.
4) Replace the battery (lithium disc-type CR 1620 or
equivalent battery) so its (+) terminal faces “+” mark
on transmitter.
5) Fit together transmitter (3) and install it into
transmitter holder (4).
6) Install transmitter cover (2) and screw (1).7) Make sure that door locks can be operated with

Precautions
Precautions in Diagnosing TroublesS6RW0DA300001
• Before confirming the diagnostic trouble code (DTC),
do not disconnect connector from ECM, battery cable
from battery, ground wire harness, or main fuse. Such
disconnection will erase DTC stored in ECM.
• DTC stored in ECM memory can be checked as well
as cleared by using SUZUKI scan tool. Before using
SUZUKI scan tool, read its operator’s manual
carefully to know how to use it and what functions are
available.
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before inspection.
• Communication of ECM, BCM, ABS control module,
TCM (if equipped), 4WD control module (if equipped),
keyless start control module (if equipped),
combination meter and DLC is established by CAN
(Controller Area Network). Therefore, handle CAN
communication lines with care referring to “Precaution
for CAN Communication System in Section 00”.
For CAN communication system, refer to description
on “CAN Communication System Description in
Section 1A”.
Precaution in Replacing ECMS6RW0DA300002
• If ECM is replaced with new or used one without
Immobilizer control function, the engine will not be
started. In case of the above, check if the newly
installed ECM has Immobilizer control function.
• After ECM is replaced with new one or used one, the
transponder code in the transponder built in the
ignition key has to be registered with ECM. Or, the
engine cannot be started up. For the registration
procedure, refer to “Procedure after ECM
Replacement”.
Precaution in Replacing Ignition KeyS6RW0DA300003
To register ignition key in case of replacing key(s) and/or
making spare key(s), the transponder code in the ignition
key is registered with ECM. Or the engine can not be
started up. For the registration procedure, refer to
“Registration of the Ignition Key”.
Precautions in Handling Immobilizer Control
System
S6RW0DA300004
• Do not turn ON ignition switch with ignition key in
contact with another one or quite close to another
one. Or, the immobilizer control system may detect
some abnormal condition and prevent the engine from
starting.
• Do not turn ON ignition switch by using ignition key
with any type of metal (1) wrapped its grip or in
contact with it. Or, the immobilizer control system may
detect some abnormal condition and prevent the
engine from starting.

Inspection of ICM and Its CircuitS6RW0DA304018
ICM and its circuit can be checked at ICM wiring connector by measuring voltage.
CAUTION!
ICM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ICM with
connector disconnected from it.

Voltage Check
1) Remove ICM (1) from steering lock assembly or steering lock unit referring to “ICM Removal and Installation”.
2) Connect ICM connector (2) to ICM.
3) 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 the
ignition switch is turned to ON position.

Removal
1) Disconnect negative (–) cable at battery.
2) Remove dash side trim (4) and steering column hole
cover (3).
3) Remove steering column covers (1).
Turn steering wheel to access steering column cover

NOTE
The antenna part of ICM is fragile. Therefore,
do not add strong power to the part or twist
the part.

Installation
Reverse the removal procedure.
Registration of the Ignition KeyS6RW0DA306002
To finish the registration of the ignition key, the
transponder code memorized in the transponder built in
the ignition key has to be registered with ECM. To
register the transponder code with ECM, perform
“Immobilizer Key Registration” mode of SUZUKI scan
tool referring to “SUZUKI scan tool Operator’s Manual”.
NOTE
• A maximum of four transponder codes can
be registered with ECM.
• At an early part of the registration process,
all transponder codes of the ignition keys
in use already registered with ECM are
cleared. Therefore, before starting the
registration, prepare all ignition keys in
use in addition to the new ignition key(s) to
be registered with ECM.

Procedure after ECM ReplacementS6RW0DA306003
After ECM is replaced with new one or used one, the
transponder code in the transponder built in the ignition
key has to be registered with ECM. To register
transponder code in the ignition key with ECM, perform
“Immobilizer Key Registration” mode of SUZUKI scan
tool referring to “SUZUKI scan tool Operator’s Manual”.
NOTE
A maximum of four transponder codes can
be registered with ECM.
