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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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).
NOTE:
Whether the following systems (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.

ENGINE GENERAL INFORMATION AND DIAGNOSIS 6-7
ON-BOARD DIAGNOSTIC SYSTEM (VEHICLE
WITH IMMOBILIZER INDICATOR LAMP)
ECM in this vehicle has following functions.
When the ignition switch is turned ON with the engine at a
stop, malfunction indicator lamp (MIL) (1) turns ON to check
the bulb of the malfunction indicator lamp (1).
When ECM detects a malfunction which gives an adverse
effect to vehicle emission while the engine is running, it
makes the malfunction indicator lamp (1) in the meter cluster
of the instrument panel turn ON or flash (flashing only when
detecting a misfire which can cause damage to the catalyst)
and stores the malfunction area in its memory.
(If it detects that continuously 3 driving cycles are normal
after detecting a malfunction, however, it makes MIL (1) turn
OFF although DTC stored in its memory will remain.)
As a condition for detecting a malfunction in some areas in
the system being monitored by ECM and turning ON the
malfunction indicator lamp (1) due to that malfunction, 2 driv-
ing cycle detection logic is adopted to prevent erroneous
detection.
When a malfunction is detected, engine and driving condi-
tions then are stored in ECM memory as freeze frame data.
(For the details, refer to description on Freeze frame data.)
It is possible to communicate by using not only SUZUKI scan
tool (Tech-1) (2) but also generic scan tool. (Diagnostic infor-
mation can be accessed by using a scan tool.)
WARM-UP CYCLE
A warm-up cycle means sufficient vehicle operation such that the
coolant temperature has risen by at least 22°C (40°F) from
engine starting and reaches a minimum temperature of 70°C
(160°F).
DRIVING CYCLE
A “Driving Cycle” consists of engine startup, driving mode where
a malfunction would be detected if present, and engine shutoff.
2 DRIVING CYCLES DETECTION LOGIC
The malfunction detected in the first driving cycle is stored in
ECM memory (in the form of pending DTC and freeze frame data)
but the malfunction indicator lamp does not light at this time. It
lights up at the second detection of same malfunction also in the
next driving cycle.
PENDING DTC
Pending DTC means a DTC detected and stored temporarily at
the first driving cycle of the DTC which is detected in the 2 driving
cycle detection logic.
