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.
