WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Manual men-
tioned in the FOREWORD of this manual.

1. 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 an inspection form (shown in next page) will facilitate collecting information to
the point required for proper analysis and diagnosis.
2. DIAGNOSTIC TROUBLE CODE (DTC) / FREEZE FRAME DATA CHECK, RECORD AND
CLEARANCE
First, referring to “DTC CHECK” in this section, check DTC (including pending DTC). If DTC exists, print or
write down DTC and freeze frame data and then clear them by referring to “DTC CLEARANCE” in this section.
DTC indicates malfunction in the system but it is not possible to know from it whether the malfunction is occur-
ring now or it occurred in the past and normal condition has been restored. In order to know that, check symp-
tom in question according to Step 5 and then recheck DTC according to Step 6.
Diagnosing a trouble based on the DTC in this step only or failure to clear the DTC in this step may result in
an faulty diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting which is otherwise un-
necessary.
3. and 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the engine
and automatic transmission referring to “VISUAL INSPECTION” in this section.
5. TROUBLE SYMPTOM CONFIRMATION
Check trouble symptoms based on information obtained in Step 1 “Customer complaint analysis” and Step
2 “DTC / freeze frame data check”.
Also, reconfirm DTC according to “DTC CONFIRMATION PROCEDURE” described in each “DTC Flow Table”
in this section.
6. and 7. RECHECKING AND RECORD OF DTC / FREEZE FRAME DATA
Refer to “DTC CHECK” in this section for checking procedure.
8. AUTOMATIC TRANSMISSION BASIC CHECK AND SYMPTOM-TO-INSPECTION TABLE
Perform basic check of A / T according to “AUTOMATIC TRANSMISSION BASIC CHECK FLOW TABLE” first.
When the end of the flow table has been reached, check the parts of the system suspected as a possible cause
referring to “SYMPTOM -TO- INSPECTION TABLE” and based on symptoms appearing on the vehicle (symp-
toms obtained through steps of customer complaint analysis, trouble symptom confirmation and / or A / T basic
check) and repair or replace faulty parts, if any.
9. DIAGNOSTIC TROUBLE CODE FLOW TABLE
Based on the DTC indicated in Step 6 and 7, and referring to “DTC Flow Table” in this section, locate the cause
of the trouble, namely in a sensor, switch, wire harness, connector, actuator, PCM or other part and repair or
replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.) referring to “IN-
TERMITTENT AND POOR CONNECTION” in Section 0A and related circuit of DTC recorded in step 2.
11. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the vehicle is free from any abnormal conditions.
If what has been repaired is related to the DTC, clear the DTC once, perform DTC confirmation procedure and
check to ensure that no DTC is indicated.
