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.

Wiring Diagram
Refer to “Immobilizer Control System Wiring Circuit Diagram”.
Detecting Condition and Trouble Area
Troubleshooting4CAN communication circuit check
1) Disconnect connectors from ECM, BCM and ABS
control module.
2) Check CAN communication circuit for open, short and
high resistance.
• Between ECM and ABS control module
• Between BCM and ABS control module
Is each CAN communication circuit in good condition?Go to Step 5. Repair circuit.
5Replacement of BCM
1) Replace BCM with new one referring to “BCM (Included
in Junction Block) Removal and Installation in Section

the one in BCM does not match.
• The registration of the immobilizer control system
information in ECM is failed.• Use of the wrong ECM
• CAN communication circuit
• Keyless start control module (if equipped)
• Combination meter
• TCM (A/T model)
• 4WD control module (if equipped)
• ABS control module
•BCM
•ECM
Step Action Yes No

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.
