Customer Complaint Analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in figure will facilitate collectin g information to the point
required for proper analysis and diagnosis. Customer questionnaire (example)
Problem Symptom Confirmation
Check if what the custom er claimed in “Customer
Questionnaire” is accurately f ound 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 me mory 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 Intermi ttent Problem
Check parts where an intermit tent trouble is easy to
occur (e.g., wire harness, connector, etc.), referring to
“Intermittent and Poor Connec tion 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.

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.
