Step 2. DTC / Freeze Frame Data Check, Record and
Clearance
First, referring to “DTC Check”, check DTC and pending
DTC. If DTC exists, print or write down DTC and freeze
frame data and then clear malfunction DTC(s) by
referring to “DTC Clearance”. Malfunction DTC indicates
malfunction 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
unnecessary.
Step 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 transaxle referring to “Visual Inspection”.
Step 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, Record and
Clearance: ”.
Also, reconfirm DTC according to “DTC Confirmation
Procedure” described in each DTC flow.
Step 6 and 7. Rechecking and Record of DTC and
Freeze Frame Data
Refer to “DTC Check” for checking procedure.Step 8. A/T Basic Check and A/T Symptom
Diagnosis
Perform basic check of A/T according to “A/T Basic
Check” first. When the end of the flow has been reached,
check the parts of the system suspected as a possible
cause referring to “A/T Symptom Diagnosis” and based
on symptoms appearing on the vehicle (symptoms
obtained through steps of customer complaint analysis,
trouble symptom confirmation and/or A/T basic check)
and repair or replace faulty parts, if any.
Step 9. Troubleshooting for DTC
Based on the DTC indicated in Step 6 / 7 and referring to
“applicable DTC flow”, locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
actuator, TCM or other part and repair or replace faulty
parts.
Step 10. 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” and related circuit of DTC recorded in Step 2.
Step 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 malfunction DTC, clear
the DTC once and check to ensure that no malfunction
DTC is indicated.

DTC ClearanceS6RW0D5104006
WARNING!
When performing a driving test, select a safe
place where there is neither any traffic nor
any traffic accident possibility and be very
careful during testing to avoid occurrence of
an accident.

After repair or replace malfunction part(s), clear all DTCs
by performing the following procedure.
1) Connect SUZUKI scan tool to data link connector in
the same manner as when making this connection
for “DTC Check”.
2) Turn ignition switch ON.3) Erase DTC and pending DTC according to
instructions displayed on scan tool. Refer to scan
tool operator’s manual for further details.
4) After completing the clearance, turn ignition switch
OFF and disconnect scan tool from data link
connector (DLC).
NOTE
DTC and freeze frame data stored in TCM
memory are also cleared in the following
cases. Be careful not to clear them before
keeping their record.
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles.

Stall TestS6RW0D5104013
This test is to check overall performance of automatic transaxle and engine by measuring stall speed at “D” and “R”
ranges. Be sure to perform this test only when transaxle fluid is at normal operating temperature and its level is
between FULL and LOW marks.
CAUTION!
• Do not run engine at stall more than 5 seconds continuously, or fluid temperature may rise
excessively high.
• After performing stall test, be sure to leave engine running at idle for longer than 1 minute before
another stall test.

1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to “P” range.
4) Depress brake pedal fully.
5) Shift select lever to “D” range and depress accelerator pedal fully while watching tachometer. Read engine rpm
quickly when it has become constant (stall speed).
6) Release accelerator pedal immediately after stall speed is checked.
7) In the same way, check stall speed in “R” range.
8) Stall speed should be within the following specification.
Engine stall speed
Standard: 2,200 – 2,600 rpm
