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.

A/T Basic CheckS6RW0D5104009
This check is important for troubleshooting when TCM has detected no DTC and no abnormality has been noted in
“Visual Inspection”. Follow the flow carefully.
Road TestS6RW0D5104010
This test is to check if upshift, downshift and lock-up take place at specified speeds while actually driving vehicle on a
level road.
WARNING!
• Carry out test in very little traffic area to prevent an accident.
• Test requires 2 persons, a driver and a tester.

1) Warm up engine.
2) With engine running at idle, shift select lever “D” range.
3) Accelerate vehicle speed by depressing accelerator pedal gradually.
4) While driving in “D” range, check if gear shift and lock-up occur properly as shown in “Automatic Gear Shift Table”. Step Action Yes No

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.

Engine Brake TestS6RW0D5104012
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.

CAUTION!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one
minute before performing another line pressure test.
