Removal and Installation
S7RS0BA206001
CAUTION!
Do not attempt removal of BCM from junction
block assembly as it may cause contact
failure.
If there is faulty condition in BCM, replace
junction block assembly.

Removal
1) Disconnect negative (–) cable from battery.
2) Disable air bag system referring to “Disabling Air Bag System in Section 8B”.
3) Remove dash side trim (1) and steering column hole cover (2).
4) Remove junction block assembly mounting nuts (3).
5) Disconnect connectors from BCM and junction block assembly.
6) Detach wiring harness clamp from junction block assembly.
Installation
Reverse removal procedure for installation, noting
following points.
• Connect connectors securely.
• Enable air bag system referring to “Enabling Air Bag System in Section 8B”.
Outside Air Temperature Sensor Removal and
Installation
S7RS0BA206002
For removal and installation, refer to “Outside Air
Temperature Sensor Removal and Installation (If
Equipped) in Section 9C”.
Outside Air Temperature Sensor InspectionS7RS0BA206003
For inspection, refer to “Outside Air Temperature Sensor
Inspection (If Equipped) in Section 9C”.
Security Alarm Mode Selection Procedure (If
Equipped)
S7RS0BA206004
Security alarm mode can be selected by performing the
following procedure.
1) Confirm that all doors are closed, all doors are unlocked and ignition key is inserted in ignition key
cylinder.
2) Remove ignition key from ignition key cylinder.
3) Perform Step a) through e) described below within 15 seconds.
a) Insert ignition key (1) in ignition key cylinder (2).
b) Remove ignition key from ignition key cylinder.
c) Repeat Step a) and b) twice.
d) Insert ignition key in ignition key cylinder.
e) Push lock side (3) of driver side manual lock switch (4) 3 times.
4) When Step 3) is completed, the mode changes to the next one automatically. The warning buzzer
(located in BCM) sounds by the number of specified
for each mode as follows.
• Changed from A mode to B mode: Buzzer sounds 4 times
• Changed from B mode to A mode: Buzzer sounds once

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.

• 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 syst em may detect some
abnormal condition and prevent the engine from
starting.
General Description
Immobilizer Control System IntroductionS7RS0BA301001
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.
• Engine Control Module (ECM)
• Immobilizer control module (ICM) with the built-in coil antenna
• Ignition key with the built-in transponder
A code called the transponder code is memorized in the tran sponder. 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 operati on of the fuel injection so as not
to start up the engine and turns the immobilizer indi cator lamp ON and OFF using CA N communication lines. In the
case of the vehicle equipped with the keyless start system , in addition to the above operation, ECM makes the
immobilizer indicator lamp ON and OFF when it detects a trouble related to ID code verification of the keyless start
system.
