FLUID LEVEL
LEVEL CHECK AT NORMAL OPERATING TEMPERATURE
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal operating
temperature (70 ± 80C / 158 ± 176F). As a guide to check fluid
temperature, warm up engine till engine coolant temperature
meter indicated around 1 unit above ªCº point.
5) Keep engine idling and shift selector slowly to L and back to P
position.
6) With engine idling, pull out dipstick, wipe it off with a clean cloth
and put it back into place.
7) Pull out dipstick again and check fluid level indicated on it. Fluid
level should be between FULL HOT and LOW HOT. If it is below
LOW HOT, add an equivalent of DEXRON-III up to FULL HOT.
Fluid specification
An equivalent of DEXRON-III
NOTE:

DO NOT RACE ENGINE while checking fluid level, even af-
ter the engine start.

DO NOT OVERFILL. Overfilling can causes foaming and
loss of fluid through breather. Then slippage and trans-
mission failure can result.

Bringing the level from LOW HOT to FULL HOT requires
0.3 liters (0.64/0.53 US/lmp.pt).

If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour af-
ter it is stopped.

8G-6 IMMOBILIZER CONTROL SYSTEM (IF EQUIPPED)
1. Immobilizer diagnostic coupler
DIAGNOSIS
ECM / PCM and Immobilizer Control Module have on-board diag-
nostic system (a system self-diagnosis function) as described pre-
viously.
Investigate where the trouble is by referring to ªDiagnostic Flow
Tableº and ªDiagnostic Trouble Code Tableº on later pages.
PRECAUTIONS IN DIAGNOSING TROUBLES
[PRECAUTIONS IN IDENTIFYING DIAGNOSTIC TROUBLE CODE]
ECM / PCM


Before identifying diagnostic trouble code indicated by malfunc-
tion indicator lamp, don't disconnect couplers from ECM / PCM,
battery cable from battery, ECM / PCM ground wire harness from
engine.
Such disconnection will clear trouble codes for electronic fuel in-
jection system stored in memory of ECM / PCM.

If abnormality or malfunction lies in two or more areas, malfunc-
tion indicator lamp indicates applicable codes three times each.
And flashing of these codes is repeated as long as diagnosis ter-
minal is grounded and ignition switch is held at ON position.

When ECM / PCM detects a trouble in both electronic fuel injec-
tion system and immobilizer control system, malfunction indicator
lamp indicates trouble codes of both systems alternately while the
ignition switch is turned ON and the diagnosis terminal is
grounded.

Take a note of diagnostic trouble code indicated first.


Before identifying diagnostic trouble code indicated through Su-
zuki scan tool, don't disconnect couplers from ECM / PCM, bat-
tery cable from battery, ECM / PCM ground wire harness from en-
gine.
Such disconnection will clear trouble codes for electronic fuel in-
jection system stored in memory of ECM / PCM.

Take a note of diagnostic trouble code indicated first.
Immobilizer Control Module

Take a note of diagnostic trouble code indicated first.

NOTE:

When 2 or more codes are indicated, the lowest numbered code will appear first.

If a code not listed on the table is displayed, then the SDM is faulty.

Current DTC and history DTC can be identified by lighting and flashing of ªAIR BAGº warning lamp as
follows.
Current DTC is set.
(Abnormality exists at present.)History DTC is set only. (Faulty condi-
tion occurred once in the past but nor-
mal condition is restored at present.)

Current DTC is displayed.History DTC is displayed.
However, if a multiple number of DTC's are set an even one of them is a current DTC, ªAIR BAGº warning
lamp remains on after ignition switch is turned ON. Therefore, it is not possible to identify any of them
as to whether it is a current one or a history one. (But use of scan tool (Tech 1) will make identification
possible.)
