Malfunction Indicator Lamp (MIL) CheckS6RW0D5104003
Refer to the same item in “Malfunction Indicator Lamp (MIL) Check in Section 1A” for checking procedure.
Transmission Warning Light Check (Non-Euro-OBD model)S6RW0D5104053
1) Turn ignition switch ON.
2) Check that transmission warning light lights for about 2 – 4 sec. and then goes OFF.
If anything faulty is found, advance “Transmission Warning Light Circuit Check – Light Does Not Come “ON” at
Ignition Switch ON (Non-Euro-OBD Model)” or “Transmission Warning Light Circuit Check – Light Remains “ON”
at Ignition Switch ON (Non-Euro-OBD Model)”.
DTC TableS6RW0D5104004
NOTE
• There are two types of OBD system depending on the vehicle specification.For identification, refer
to “Precaution on On-Board Diagnostic (OBD) System in Section 1A”.
• For non-Euro-OBD model, some of DTC No. with (*) mark in the following table can not be detected
by TCM depending on vehicle specification and local regulation.
• With the CAN communication OBD generic scan tool, DTC No. with delta (U) mark in the following
table can not be read.
• A: Driving cycles when MIL lighting and storing DTC in TCM memory for Euro OBD model.
• B: Driving cycles when transmission warning light lighting and storing DTC in TCM memory for non-
Euro-OBD model.
• 1 driving cycle: MIL or transmission warning light lights up when DTC is detected during 1 driving
cycle.
• 2 driving cycles: MIL or transmission warning light lights up when the same DTC is detected also in
the next driving cycle after DTC is detected and stored temporarily in the first driving cycle.
• Driving cycle with (*): MIL or transmission warning light does not light up but TCM detects and
stores DTC.

Also check the following items at engine start, if possible.
• Malfunction indicator lamp ----- Operation “Malfunction Indicator Lamp (MIL) Check”
• Transmission warning light ----- Operation “Transmission Warning Light Check (Non-Euro-
OBD model)”
• Charge warning lamp ----- Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp ----- Operation “Oil Pressure Warning Light Symptom Diagnosis in
Section 9C”
• Engine coolant temp. meter ----- Operation “Engine Coolant Temperature (ECT) Meter

DTC CheckS6RW0D5104005
NOTE
• There are two types of OBD system
depending on the vehicle specification.For
identification, refer to “Precaution on On-
Board Diagnostic (OBD) System in Section
1A”.
• For Euro-OBD model, the MIL is turned on
when the ECM and/or TCM detect
malfunction(s). Each control module
stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool. Therefore, check both of the control
modules for any DTC with the SUZUKI
scan tool because the DTC stored in ECM
and TCM is not read and displayed at a
time. However, each of the control
modules needs not to be checked with the
CAN communication OBD generic scan
tool because the DTC stored in ECM and
TCM is read and displayed at a time. In
case using CAN communication OBD
generic scan tool, refer to “DTC Table in
Section 1A”.

1) Turn ignition switch to OFF position.
2) Connect scan tool to data link connector (DLC) (1).
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
3) Turn ignition switch ON.
4) Read DTC, pending DTC and freeze frame data
according to instructions displayed on scan tool and
print it down. Refer to scan tool operator’s manual
for further details.
If communication between scan tool and TCM is not
possible, check if scan tool is communicable by
connecting it to TCM in another vehicle. If
communication is possible in this case, 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 scan tool from data link connector. ) UP1723 Range select switch malfunction“3” position switch ON signal is inputted

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.

Scan Tool DataS6RW0D5104008
As the data values given in the following table are standard values estimated on the basis of values obtained from the
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good
condition, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by the scan tool are those detected by TCM and output from
TCM as commands and there may be cases where the automatic transaxle or actuator is not operating (in the
condition) as indicated by the scan tool.
NOTE
The following scan tool data related to automatic transaxle can be checked only by communicating
with TCM.

Manual Road TestS6RW0D5104011
WARNING!
Carry out test in very little traffic area to prevent an accident.
Test requires 2 persons, a driver and a tester.

The purpose of this test is to judge whether causal factor of trouble which occurred in automatic transaxle is electrical
or mechanical by disconnecting valve body harness connector (1) and fixing automatic transaxle gear position.
1) Start engine and warm it up to normal operating temperature.
2) Turn ignition switch to OFF position and disconnect valve body harness connector (1).
3) Turn OFF all electrical loads.
With select lever shifted to each range (“L”, “2”, “3” and “D”), drive vehicle at 1,000 rpm engine speed and then
check vehicle speed by referring to “Fixed gear position”.
If vehicle speed is not as specified in “Fixed gear position” table, go to troubleshooting.
4) Connect valve body harness connector and clear DTC.

WARNING!
Before test, make sure that there is no vehicle behind so as to prevent rear-end collision.

1) While driving vehicle in 3rd gear of “D” range, shift select lever down to “2” range and check if engine brake
operates.
2) In the same way as in Step 1), check engine brake for operation when select lever is shifted down to “L” range.
3) Engine brake should operate in the test.
