Repair Instructions
Immobilizer Control Module (ICM) Removal and
Installation
S7RS0BA306001
Removal1) Disconnect negative (–) cable at battery.
2) Remove steering wheel referring to “Steering Wheel Removal and Installa tion in Section 6B”.
3) Remove steering column lower and upper covers.
4) Remove knee protector plate (1). (if equipped)
5) Remove engine start knob (2). (if equipped with keyless start system)
6) Disconnect connector (1) from ICM (2).
7) Remove a screw (3) from ICM.
8) Remove ICM from steering lock assembly or steering lock unit.
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 KeyS7RS0BA306002
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
“Register Ig Key” mode of SU ZUKI scan tool referring to
“SUZUKI Tech 2 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 ReplacementS7RS0BA306003
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
“Replace New ECM” mode of SUZUKI scan tool
referring to “SUZUKI Tech 2 Operator’s Manual”.
NOTE
A maximum of four transponder codes can
be registered with ECM.

Diagnostic Information and Procedures
Precautions in Diagnosing TroublesS7RS0BA504001
• The keyless start system executes data transmission/reception by means of th e radio wave. Therefore,
proper operation may not be obtained if use of the
door lock function and engine start function of the
keyless start system is attempted near the place
where strong radio wave is emitted (TV and radio
broadcasting stations, etc.).
• Diagnostic information stored in keyless start control
module memory can be checked only by key indicator
lamp.
• Be sure to use the trouble diagnosis procedure as described in “Keyless Start System Check”. Failure to
follow it may result in incorrect diagnosis. (Some other
DTC may be stored by mistake in the memory of
keyless start control module during inspection.)
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• Communication of ECM, BCM, TCM (A/T model), ABS control module, keyless start control module and
combination meter is estab lished by CAN (Controller
Area Network). (For detail of CAN communication for
keyless start control module, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”. • Replacement of the keyless start control module
When keyless start control module is replaced with
new one, make sure that r egister remote controller ID
code to keyless start co ntrol module correctly
according to “Registration Procedure for Remote
Controller ID Code”.
• Keyless start control module substitution When the keyless start control module used in
another vehicle was installed in the vehicle, register
the ID code of the remote controller in the keyless
start control module as well as the ignition key
transponder code fo r the immobilizer control system in
ECM. For the registration procedure of the ignition key
transponder code, refer to “Registration of the Ignition
Key in Section 10C”.
Self-Diagnosis FunctionS7RS0BA504002
The keyless start control module has self-diagnosis
function to monitor the system components and circuits
while the keyless start system is at work. When the
keyless start control module detects an abnormality in
the system, it saves the ar ea where such abnormality
has occurred as a DTC in its memory. The DTC stored in
memory of the keyless start control module is indicated
by the key indicator lamp in the combination meter
flashing in a specific pattern. For DTC indication, refer to
“DTC Check” and for the clearing procedure, to “DTC
Clearance”.
Keyless Start System Diagnosis IntroductionS7RS0BA504003
To ensure that the trouble diagnosis is done accurately
and smoothly, observe “Precautions in Diagnosing
Troubles” and follow “Keyless Start System Check”.
Keyless Start System CheckS7RS0BA504004
Step Action YesNo
1 1) Record details of the problem. For your record, use of a questionnaire form will facilit ate collecting information for
proper analysis and diagnosis.
2) Check if the problem described in “Customer Questionnaire (Example)” actually occurs in the vehicle.
(This step should be performed with the customer if
possible.)
Perform “Keyless Start System Operation Inspection”
procedure to check if the symptom which has occurred is
abnormal or not.
3) Check for DTC referring to “DTC Check”, and then record DTC(s).
4) Clear DTC referring to “DTC Clearance” if any DTC exists, and then recheck for DTC.
Is any DTC still detected? Go to Step 2.
Go to Step 3.
2 1) Check and repair referring to applicable “DTC Table”. Are check and repair complete? Go to Step 5.
Check and repair
malfunction part(s), and
go to Step 5.

DTC No. 13 / No. 14: Release Signal Error from Steering Lock Unit / Steering Lock Unit MalfunctionS7RS0BA504018
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Check DTC referring to “DTC Check”.
Troubleshooting
Replace steering lock unit and recheck.
NOTE
DTC No. 13 is also set is such case where the keyless start control module which was used in another
vehicle is installed, the remote controller ID code is registered in it but the ignition key transponder
code is not registered in ECM. Therefore, when DTC No. 13 is detected, register the ignition key
transponder code in ECM before replacing the steering lock unit.

3) Remove battery (4) from lower case (5).
CAUTION!
Use care not to allow grease or dirt to be
attached on the printed circuit board and the
battery.

4) Replace the battery (lithium disc-type CR 2032 or equivalent battery) so its (+) terminal faces on
remote controller lower case.
5) Install printed circuit board and rubber switch to upper case and then fit lower case securely.
NOTE
• To prevent theft, be sure to break the remote controller be fore discarding it.
• Dispose of the used battery properly according to applicable rules or
regulations. Do not dispose of lithium
batteries with ordinary household trash.

Registration Procedure for Remote Controller
ID Code
S7RS0BA506009
NOTE
• It is possible to register up to 4 remote controllers in keyless start control module.
• Setting keyless start control module to ID code registration mode of remote
controller will erase all remote controller ID
codes that have been registered in keyless
start control module.
Therefore, when re gistering remote
controller ID codes in keyless start control
module, have all of those to be registered
ready and execute their registration at the
same time.
• When registration of more than four remote controller ID codes is attempted,
the oldest remote cont roller ID code will be
erased and that inputted after the fourth
one will be registered.
• When keyless start control module which was used in another vehicle has been
installed, it is nece ssary to perform both
registration of remote controller ID code in
keyless start control module and
registration of ignition key transponder
code in ECM. For registration procedure of
ignition key transponder code, refer to
“Registration of the Ignition Key in Section
10C”.
