is removed from keyhole of ignition switch, or brake
pedal is not depressed. 2) Shift select lever to “P” range position, release knob
button and check for the following.
• Ignition key can be turned between LOCK and ACC positions back and forth and also it can be
removed from ignition switch.
Step Action Yes No
1 Check TCM back-up power circuit
1) Disconnect TCM connector with ignition switch OFF.
2) Check for proper connection to TCM at “C34-24”
terminal.

• With ignition switch turned to ACC position, push
shift lock solenoid release button (1). Then, select
lever can be shifted from “P” range position to any
other range.
• While ignition switch is at LOCK position, even when shift lock solenoid release button (1) is
pressed, select lever cannot be shifted from P
range position to any other range.
• When ignition switch is turned ON and brake pedal is depressed, select lever can be shifted
from “P” range position to any other range. 3) With select lever shifted to any position other than
“P” range, check that ignition key cannot be turned
LOCK position and it cannot be removed from
ignition switch unless it is at LOCK position.

A/T Fluid Level CheckS7RS0B5106002
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 Check1) Drive vehicle so that A/T fluid temperature reach the
normal operating temperature (70 – 80 °C (158 –
176 °F)).
2) Stop vehicle with engine running and place it level.
3) With select lever at “P” range, apply parking brake and place chocks against wheels.
4) Keep engine idling and shift selector slowly to “L” and back to “P” position.
5) With engine idling, pull out fluid level gauge, wipe it off with a clean cloth and put it back into place.
6) Pull out fluid level gauge (1) again and check fluid level indicated on it. The lo west 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 temp erature, 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.
