Customer questionnaire (example)
Problem Symptom Confirmation
Check if what the customer claimed in “Customer Questionnaire” is accurately found in the vehicle. If that symptom is
found, check whether the symptom is identified as a failure. (This step should be shared with the customer if possible.)
DTC Check
Check DTC stored in BCM memory referring to “DTC Check”, record it and then clear it referring to “DTC Clearance”.
DTC indicates malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the
past and the normal condition has been restored now. To check which case applies, clear DTC once and check
whether or not any fault exists.
Troubleshooting for DTC
Based on the DTC indicated in Step 3 and referring to applicable DTC flow, locate the cause of the trouble, namely in
a sensor, wire harness, connector, BCM or other part and repair or replace faulty parts.
Body Electrical Control System Symptom Diagnosis
Check the parts or system suspected as a possible cause referring to symptom diagnosis of each system.
Check for Intermittent Problem
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section 00”.
Final Confirmation Test
Confirm that the problem symptom has gone and the body electrical control system is free from any abnormal
conditions. If what has been repaired is related to the malfunction DTC, check DTC again and confirm that no DTC is
indicated.

DTC CheckS6RW0DA204005
Using SUZUKI Scan Tool
1) Prepare SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to data link connector (DLC) located on underside of instrument panel
of driver’s side.
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch ON.
4) Read DTC according to instructions displayed on SUZUKI scan tool and print it or write it down.
Refer to SUZUKI scan tool operator’s manual for further details.
If communication between SUZUKI scan tool and BCM is not possible, check if SUZUKI scan tool is
communicable by connecting it to BCM in another vehicle. If communication is possible in this case, SUZUKI scan
tool is in good condition. Then check data link connector and serial data line (circuit) in the vehicle with which
communication was not possible.
5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from data link connector.
Without Using SUZUKI Scan Tool
1) Turn ignition switch to OFF position.
2) Perform following Steps a) to d) within 10 seconds after ignition switch is turned ON and engine stops.
a) Turn headlight switch to “SMALL” position.
b) Turn headlight switch to “OFF” position.
c) Repeat Steps a) and b) 2 times.
d) Press and release driver side door switch 3 times.

Inspection of BCM and Its CircuitsS6RW0DA204017
BCM and its circuits can be checked at BCM wiring couplers by measuring voltage and resistance.
CAUTION!
BCM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to BCM
with couplers disconnected from it.

Voltage Check
1) Disconnect negative cable (–) at battery.
2) Remove BCM (included in junction block) referring to “BCM (Included in Junction Block) Removal and Installation”.
3) Connect connectors to BCM (1) and junction block (2).
4) Check voltage at each terminal number of couplers connected.
For connector and terminal number, refer to “Connector Layout Diagram of BCM and Junction Block”.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) can not be measured by voltmeter because it is pulse signal.
Check it with oscilloscope if necessary.

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.

1Immobilizer indicator light check
1) Turn ignition switch to ON position using ignition key.
Does immobilizer indicator light come on?Go to Step 2. Check if DTC P1636
and/or P1638 are
detected by ECM
referring to “DTC
Check”. If detected, go
to applicable DTC diag.
flow. If not detected, go
to “Immobilizer Indicator
Light Does Not Come
ON with Ignition Switch
ON and Engine Stop”.
2Immobilizer indicator light check
Does immobilizer indicator light flash on and off continuously
in Step 1?Check ECM for DTC
referring to “DTC
Check”. Then, go to
applicable DTC diag.
flow.Go to Step 3.
3Engine start check
1) Start engine using ignition key.
Does engine start?Go to Step 4. Go to “Engine and
Emission Control
System Check in
Section 1A”.
4Immobilizer indicator light check
1) Check if immobilizer indicator light remains ON after
engine start.
Does immobilizer indicator light remains ON after engine
start?Go to “Immobilizer
Indicator Light Remains
ON after Engine Start”.Immobilizer control
system is in good
condition. Then, go to
“Keyless Start System
Check in Section 10E”
for keyless start model.
