IMPORTANT
WARNING/CAUTION/NOTE
Please read this manual and follow its instructions carefully. To emphasize special information, the words
WARNING, CAUTION
and NOTE
have special meanings. Pay special attention to the messages highlighted by
these signal words.
WARNING:
Indicates a potential hazard that could result in death or injury.
CAUTION:
Indicates a potential hazard that could result in vehicle damage.
NOTE:
Indicates special information to make maintenance easier or instructions clearer.
WARNING:
This service manual is intended for authorized Suzuki dealers and qualified service mechanics only.
Inexperienced mechanics or mechanics without the proper tools and equipment may not be able to
properly perform the services described in this manual.
Improper repair may result in injury to the mechanic and may render the vehicle unsafe for the driver
and passengers.
WARNING:
For vehicles equipped with a 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.
 If the air bag system and another vehicle system both need repair, Suzuki recommends that the air
bag system be repaired first, to help avoid unintended air bag system activation.
 Do not modify the steering wheel, instrument panel or any other air bag system component (on or
around air bag system components or wiring). Modifications can adversely affect air bag system
performance and lead to injury.
 If the vehicle will be exposed to temperatures over 93°C (200°F) (for example, during a paint baking
process), remove the air bag system components (air bag (inflator) modules, SDM and/or seat belt
with pretensioner) beforehand to avoid component damage or unintended activation.

screws (1) and disconnect connectors (2) from combination
switch (3).
6) Disconnect horn connector (1) from instrument panel har-
ness.
7) Remove contact coil and combination switch assembly from

ING WHEEL”.
STEERING COLUMN ASSEMBLY
NOTE:
New contact coil and combination switch assembly is
supplied with contact coil set and held at its center posi-
tion with a lock pin (1) and seal (2). Remove this lock pin
after installing contact coil and combination switch
assembly to steering column.

CAUTION:
Once the steering column is removed from the vehicle,
the column is extremely susceptible to damage.
Dropping the column assembly on its end could col-
lapse the steering shaft or loosen the plastic shear
pins which maintain column length.
Leaning on the column assembly could cause it to
bend or deform.
Any of the above damage could impair the column’s col-
lapsible design.
NOTE:
When servicing steering column or any column-mounted
component, remove steering wheel. But when removing
steering column simply to gain access to instrument
panel components, leave steering wheel installed on
steering column.

STEERING WHEEL AND COLUMN 3C-13
11) Disconnect horn connector (1) from instrument panel har-
ness.

switch), remove it, referring to “STEERING LOCK ASSEM-
BLY (IGNITION SWITCH)” in this section.
CAUTION:
Don’t separate steering column assembly into steering
column and shaft. If column or shaft is defective, replace
as an assembly.

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.
