NOTE
To know how to use SUZUKI scan tool in
detail, refer to its operator’s manual.

Using Scan Tool
1) Turn the ignition switch to OFF position,
2) Connect SUZUKI scan tool to data link connector (DLC) (1) located under instrument panel at driver’s
seat side.
Special tool
(A): SUZUKI scan tool 3) Turn the ignition switch to ON position.

Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Turn ignition switch to ON position.
2) Check DTC in ECM.
Troubleshooting
DTC P1615: ID Code Does Not Registered (Vehicle equipped with keyless start system only)S7RS0BA304009
Circuit Description
When the transponder code of the ignition key is registered in ECM, the remote controller ID code is also registered in
ECM and keyless start contro l module at the same time.
DTC P1615 is detected only when the remote controller ID code cannot be registered in ECM and keyless start control
module when the ignition key is registered.
NOTE
• Perform troubleshooting of DTC P1618 if both DTC P1615 and P1618 have been detected.
• After replacing ECM, be sure to register the tran sponder code in the ignition key with ECM referring
to “Registration of the Ignition Key”. After replac ing the keyless start control module of the vehicle
equipped with the keyless start system, be sure to register referring to “Registration of the Ignition
Key”.

Step
Action YesNo
1 Was “Immobilizer Control S ystem Check” performed? Go to Step 2.Go to “Immobilizer
Control System Check”.
2 DTC check of ECM
1) Check if DTC other than P1614 is detected referring to
“Diagnostic Trouble Code (DTC) Check”.
Is DTC other than P1614 detected? Go to applicable DTC
diag. flow.
Go to Step 3.
3 Registration of ignition key in use with ECM
1) Register ignition key in use with ECM referring to
“Registration of the Ignition Key”.
Was registration of ignition key completed? Unregistered ignition
key.
Go to step 4.
4 Registration of spare ignition key with ECM
1) Register spare ignition key with ECM referring to
“Registration of the Ignition Key”.
Was registration of spare ignition key completed? Replace ignition key
which can not be
registered.
Substitute a known-
good ECM and recheck.
Detecting Condition
Trouble Area
• While registering the transponder code in the transponder built in the ignition key in ECM, the keyless
start control module sent a signal to ECM indicating that
the ID code could not be registered.
• The ID code could not be registered in the keyless start control module or ECM. • Circuit between steering lo
ck unit and keyless start
control module
• CAN communication circuit
• Steering lock unit
• Keyless start control module
•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 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”.
