1) Inspect transmission fluid temperature sensor referring
to “Transmission Fluid Temperature Sensor Inspection”.
Is result satisfactory?Go to Step 3 Replace transmission
fluid temperature
sensor.
3Check for transmission fluid temperature sensor circuit
1) Turn ignition switch to OFF position.
2) Disconnect valve body harness connector and TCM
connectors.
3) Check for proper connection to TCM at terminals “C06-
11” and “C06-12”. If connection is OK, check circuit for
open, short and high resistance for the following circuit.
• Between “C06-11” terminal of TCM connector and “LT
GRN” terminal of valve body harness connector.
• Between “C06-12” terminal of TCM connector and
“ORN” terminal of valve body harness connector.
Are they in good condition?Intermittent trouble or
faulty TCM. Check for
intermittent referring to
“Intermittent and Poor
Connection Inspection
in Section 00”. If OK,
substitute a known-
good TCM and recheck.Repair “LT GRN” and/or
“ORN” circuit.

DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory and start engine and keep for 20 minutes or more.
3) Stop vehicle and check DTC.

A/T Fluid Level CheckS6RW0D5106002
CAUTION!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.

Level Check at Normal Operating (Hot) Temperature
– Hot Check
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against
wheels.
3) With select lever at “P” position, start engine.
4) Warm up engine till fluid temperature reaches
normal operating temperature (70 – 80 °C / 158 –
176 °F). As a guide to check fluid temperature, warm
up engine to normal operating.
5) Keep engine idling and shift select lever slowly to “L”
and back to “P” position.
6) With engine idling, pull out fluid level gauge, wipe it
off with a clean cloth and put it back into place.

7) Pull out fluid level gauge (1) again and check fluid
level indicated on it. The lowest fluid level should be
between FULL HOT (2) and LOW HOT (3). If it is
below LOW HOT, add SUZUKI ATF 3317 or Mobil
ATF 3309 up to FULL HOT.
Automatic transaxle fluid
SUZUKI ATF 3317 or Mobil ATF 3309
NOTE
• Do not race engine while checking fluid
level, even after the engine start.
• Do not overfill. Overfilling can cause
foaming and loss of fluid through breather.
Then slippage and transaxle failure can
result.
• Bringing the level from LOW HOT to FULL
HOT requires 0.4 liters (0.85 / 0.70 US/Imp.
pt).
• If vehicle was driven under high load such
as pulling a trailer, fluid level should be
checked about half an hour after it is
stopped.

Level Check at Room (Cold) Temperature – Cold
Check
Fluid level can be checked temporarily at room (cold)
temperature which correspond to 20 – 30 °C (68 – 86
°F). This level check is considered to be preparation
before performing level check under normal operating
(hot) temperature. Checking procedure itself is the same
as that described in “Level Check at Normal Operating
(Hot) Temperature – Hot Check: ”. If fluid level is
between “FULL COLD” (4) and “LOW COLD” (5),
proceed to test drive. And when fluid temperature has
reached normal operating temperature, check fluid level
again and adjust it as necessary.
CAUTION!
Fluid level check at room (cold) temperature
is recommended only for preparation of level
check under normal (hot) operating
condition.
Failure to perform fluid level check under
normal (hot) operating temperature may
result in damage to transaxle.

A/T Fluid ChangeS6RW0D5106003
CAUTION!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.

1) Lift up vehicle.
2) Remove left side engine under cover.
3) When engine is cool, remove drain plug (1) from oil
pan (2) and drain A/T fluid.
4) Install drain plug (1).
