Replacement of Transmitter Battery (Other than
Keyless Start Model)
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
transmitter.
NOTE
• To prevent theft, be sure to break the
transmitter before discarding it.
• Dispose of the used battery properly
according to applicable rules or
regulations. Do not dispose of lithium
batteries with ordinary household trash.

Programming Transmitter Code for Keyless
Entry System (Other than Keyless Start Model)
S6RW0D9606015
NOTE
• Three transmitter codes can be registered.
• When a new transmitter code is registered,
the oldest one will be cleared.
• As for vehicle equipped with keyless start
system, perform “Registration Procedure
for Remote Controller ID Code in Section
10E” instead of “Programming Transmitter
Code for Keyless Entry System (Other than
Keyless Start Model)”.

If transmitter or BCM (included in junction block
assembly) is replaced with a new one or additional
transmitter(s) is necessary, program transmitter code(s).
1) Confirm that all doors are closed and ignition key is
out of ignition key cylinder.
2) Open driver side door.
3) Turn ignition switch to ON position, and then drawn
ignition key from ignition key cylinder within 10
seconds after that.
4) Push and release driver side door switch (1) at 3
times by hand within 20 seconds after removing
ignition key from ignition key cylinder.
5) Turn ignition switch to ON position, and then drawn
ignition key from ignition key cylinder within 10
seconds after that. All doors automatically lock and
unlock once.
With this, registration mode.

Immobilizer Indicator Light Does Not Come
ON with Ignition Switch ON and Engine Stop ..10C-9

Downloaded from www.Manualslib.com manuals search engine 10C-2 Immobilizer Control System:
• Do not leave ignition key in a place where
temperature is high. High temperature may cause
damage to the transponder built in the ignition key.• Do not turn ignition switch to ON position by bringing
radio antenna close to coil antenna. Or, the
immobilizer control system may detect some
abnormal condition and prevent the engine from
starting.
General Description
Immobilizer Control System IntroductionS6RW0DA301001
The immobilizer control system is an anti-theft device that immobilizes the vehicle. It stops the engine from working
and prevents the vehicle from being stolen. It mainly consists of the following components. For immobilizer control
system components location, refer to “Immobilizer Control System Components Location”.
•ECM
• ICM with the built-in coil antenna
• Ignition key with the built-in transponder
A code called the transponder code is memorized in the transponder. And, the code is registered with ECM. Basically,
when the ignition switch is turned ON, ECM reads the code by the coil antenna. Then, if the code in transponder in the
ignition key does not match with the one registered with ECM, ECM stops the operation of the fuel injection so as not
to start up the engine and turns the immobilizer indicator light ON and OFF using CAN communication lines. (In
addition to the above operation, ECM also turns the immobilizer indicator light ON and OFF when some trouble is
detected in the keyless start system.)
On-Board Diagnostic System Description (Self-diagnosis Function)S6RW0DA301002
ECM diagnoses if there is any trouble with the immobilizer control system. The diagnostic information is stored as the
diagnostic trouble code (DTC) in ECM. To read the diagnostic information, use SUZUKI scan tool referring to “DTC
Check”.
With the ignition switch turned ON (but the engine at stop) regardless of the condition of the engine and emission
control system, ECM indicates whether there is any trouble with the immobilizer control system or not by either lighting
ON or flashing ON and OFF the immobilizer indicator light.
Immobilizer indicator light lights ON:
No trouble exists in the immobilizer control system. (After starting up the engine, the light turns OFF.)
Immobilizer indicator light flashes ON and OFF:
There is some trouble in the immobilizer control system or in the keyless start system. Its diagnostic information is
stored in ECM.

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 before 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
S6RW0DA506009
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 registering 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 controller 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, register the ID code of the remote
controller to the keyless start control
module first and then the following code.
– With immobilizer control system,
register the ignition key transponder
code for the immobilizer control system
in ECM. For registration procedure of
that, refer to “Registration of the Ignition
Key in Section 10C”.
– Without immobilizer control system,
register the steering lock unit ID code in
keyless start control module. For
registration procedure of that, refer to
“Keyless Start Registration”.
