[For Vehicle without Monitor Connector]
ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing functions. Refer to Section 6 / 6-1 for details.

When the ignition switch is turned ON with the engine at a stop,
malfunction indicator lamp (MIL) turns ON to check the bulb of the
MIL.

When PCM detects a malfunction in A / T control system (and / or
a malfunction which gives an adverse effect to vehicle emission)
while the engine is running, it makes the malfunction indicator
lamp in the meter cluster of the instrument panel turn ON and
stores the malfunction area in its memory. (If it detects that contin-
uously 3 driving cycles are normal after detecting a malfunction,
however, it makes MIL turn OFF although DTC stored in its
memory will remain.)

It is possible to communicate through DLC by using not only SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing functions. Refer to Section 6 / 6-1 for details.

When the ignition switch is turned ON with the engine at a stop,
malfunction indicator lamp (MIL) turns ON to check the bulb of the
MIL.

When PCM detects a trouble in electronic shift control system, it
stores its trouble code in back-up memory in itself. (The memory
is kept as it is even if the trouble was only temporary and disap-
peared immediately. And it is not erased unless the power to PCM
is shut off for 30 seconds or longer.)

It is possible to communicate through DLC by using not only SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

It is also possible to communicate by not using scan tool. PCM
indicates trouble area in memory by means of flashing of malfunc-
tion indicator lamp at the time of inspection (i.e. when diagnosis
switch terminal is grounded and ignition switch is turned ON).

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 a inspection form 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 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 section. DTC indicates malfunc-
tion in the system but it is not possible to know from it whether the malfunction is occurring now or it occurred
in the past and normal condition has been restored. In order to know that, check symptom 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 unnec-
essary.
3 and 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the A / T and
engine referring to Visual Inspection section.
5. TROUBLE SYMPTOM CONFIRMATION
Check trouble symptoms based on information obtained in Step 1 ªCUSTOMER COMPLAINT ANALYSISº and
Step 2 ªDTC/FREEZE FRAME DATA CHECKº.
Also, recheck DTC according to ªDTC Confirmation Procedureº described in each ªDTC FLOW TABLEº.
6 and 7. RECHECKING AND RECORD OF DTC/FREEZE FRAME DATA
Refer to ªDTC Checkº section for checking procedure.
8. A/T BASIC CHECK AND TROUBLE DIAGNOSIS TABLE
Perform A / T basic check according to the ªA / T Basic Check Flow Tableº first. When the end of the flow table
has been reached, check the parts of the system suspected as a possible cause referring to TROUBLE DIAG-
NOSIS TABLE and based on symptoms appearing on the vehicle (symptoms obtained through steps of custom-
er 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 ªDIAGNOSTIC TROUBLE CODE FLOW TABLEº
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
ªINTERMITTENT AND POOR CONNECTIONº 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 A / T is free from any abnormal conditions.
If what has been repaired is related to the malfunction DTC, clear the DTC once, set conditions under which
DTC was detected and A / T and/or vehicle was repaired and confirm that no DTC is indicated.
