WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

[For Vehicle without Monitor Connector]
ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing functions. Refer to Section 6 / 6-1 for details.

When the ignition switch is turned ON with the engine at a stop,
malfunction indicator lamp (MIL) turns ON to check the bulb of the
MIL.

When PCM detects a malfunction in A / T control system (and / or
a malfunction which gives an adverse effect to vehicle emission)
while the engine is running, it makes the malfunction indicator
lamp in the meter cluster of the instrument panel turn ON and
stores the malfunction area in its memory. (If it detects that contin-
uously 3 driving cycles are normal after detecting a malfunction,
however, it makes MIL turn OFF although DTC stored in its
memory will remain.)

It is possible to communicate through DLC by using not only SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

ON-BOARD DIAGNOSTIC SYSTEM
For automatic transmission control system, PCM (ECM) has follow-
ing functions. Refer to Section 6 / 6-1 for details.

When the ignition switch is turned ON with the engine at a stop,
malfunction indicator lamp (MIL) turns ON to check the bulb of the
MIL.

When PCM detects a trouble in electronic shift control system, it
stores its trouble code in back-up memory in itself. (The memory
is kept as it is even if the trouble was only temporary and disap-
peared immediately. And it is not erased unless the power to PCM
is shut off for 30 seconds or longer.)

It is possible to communicate through DLC by using not only SU-
ZUKI scan tool (Tech-1) but also generic scan tool. (Diagnostic in-
formation can be accessed by using a scan tool.)

It is also possible to communicate by not using scan tool. PCM
indicates trouble area in memory by means of flashing of malfunc-
tion indicator lamp at the time of inspection (i.e. when diagnosis
switch terminal is grounded and ignition switch is turned ON).
