Precautions
Precautions in Diagnosing TroublesS7RS0BA300001
• 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, keyless start control module (if equipped), ABS / ESP ® control module,
steering angle sensor (ESP ® model), combination
meter and TCM (A/T model) 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 ECMS7RS0BA300002
• 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”.
Precautions in Handling Immobilizer Control
System
S7RS0BA300003
• Do not turn ON ignition sw itch with ignition key in
contact with another one or quite close to another
one. Or, the immobilizer co ntrol 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 i mmobilizer control system may
detect some abnormal condition and prevent the
engine from starting.

Wiring Diagram
Refer to “Immobilizer Control S ystem Wiring Circuit Diagram”.
Circuit Description
When the ignition switch is turned ON, ECM read the code by the coil antenna from ignition key. Then if the code in
transponder in the key match with the one registered with ECM, transmits indication ON signal of immobilizer indicator
lamp to combination meter in order to turn immobilizer indicator lamp on. And then, combination meter turns
immobilizer indicator lamp on. When th e engine starts to run and no malfunction is detected in the system, ECM
transmits immobilizer indicator lamp indication O FF signal to combination meter in order to turn immobilizer indicator
lamp off. And then, comb ination meter turns immobilizer indicator lamp off, but if a malfunction was or is detected,
immobilizer indicator lamp is flashes ON and OF F, when ignition switch turn to ON position.
