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.

TroubleshootingStep Action Yes No 1 Combination meter power and ground circuit check
1) Turn ignition switch to ON position.
Do warning lights in combi nation meter other than key
indicator lamp light up? Go to Step 2. Check main fuse, circuit
fuse, combination meter
power and ground
circuit.
2 Keyless start control module power and ground circuit
check
1) Check keyless start control module power and ground
circuit for condition referrin g to “Keyless Start Control
Module Power and Ground Circuit Check”.
Is it in good condition? Go to Step 3. Repair circuit.
3 Steering lock unit ignition knob switch check
1) Check ignition knob switch of steering lock unit for
operation referring to “Steering Lock Unit Inspection”.
Is it in good condition? Go to Step 4. Replace steering lock
unit.
4 Wire harness check
1) Turn ignition switch to OFF position.
2) Disconnect connector from ke yless start control module,
steering lock unit and combination meter.
3) Check for open, short and high resistance in. • Between “G22-2” terminal of steering lock unit connector and “G42-34” terminal of keyless start
control module connector
• Between “G28-7” terminal of combination meter connector and “G42-19” terminal of keyless start
control module connector
• Between “G28-9” terminal of combination meter connector and “G42-18” terminal of keyless start
control module connector
Is it in good condition? Go to Step 5. Repair circuit.
5 Keyless start system operation check
1) With remote controller of which ID code is registered in
keyless start control module carried with you, try to turn
ignition knob switch.
Can it be turned to any position other than “LOCK” position? Replace combination
meter.
Substitute a known-
good keyless start
control module and
recheck.

Step Action YesNo
1 Fuse check
1) Turn ignition switch to OFF position.
2) Check circuit fuse and main fuse for condition.
Are fuses in good condition? Go to Step 2.
Replace fuse(s) and
check for short.
2 Power supply circuit check
1) Disconnect connector from keyless start control module.
2) Check for proper connection to “G42-10”, “G42-11” and
“G42-15” terminals of keyless start control module
connector.
3) If OK, measure voltage between the following terminals. • When ignition switch is at OFF positionBetween “G42-10” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ACC position Between “G42-11” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ON position Between “G42-15” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
Is check result satisfactory? Go to Step 3.
Repair power supply
circuit.
3 Ground circuit check
1) Check for proper connection to “G42-9” terminal of
keyless start control module connector.
2) If OK, measure resistance between “G42-9” terminal of keyless start control module connector and vehicle body
ground.
Is resistance 1
Ω or less? Power and ground
circuit is in good
condition.
Repair ground circuit.
