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).

DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(IMMOBILIZER CONTROL MODULE)
1) Using analog type voltmeter, connect positive probe to diagnos-
tic output terminal and negative probe to ground of immobilizer
diagnostic coupler with ignition switch turned ON.
2) Read deflection of voltmeter indicator which represents DTC as
shown in example below and write it down. For details of DTC,
refer to Immobilizer Control Module side in ªDiagnostic Trouble
Code Tableº.
If voltmeter indicator dose not deflect, go to ªDiagnostic Flow
Table Aº.
NOTE:
If abnormality or malfunction lies in two or more areas, volt-
meter indicates applicable codes three times each.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK (ECM/PCM)
[Not using SUZUKI scan tool] (Vehicle equipped with
monitor coupler)
1) Using service wire, ground diagnostic switch terminal in monitor
coupler.
2) Read DTC from flashing pattern of malfunction indicator lamp as
shown in example below and write it down. For details of DTC,
refer to ECM / PCM side in ªDiagnostic Trouble Code Tableº.
If lamp remains ON, go to ªMalfunction Indicator Lamp Checkº
in Section 6.
NOTE:
If abnormality or malfunction lies in two or more areas, mal-
function indicator lamp indicates applicable codes three
times each.
And flashing of these codes is repeated as long as diagno-
sis terminal is grounded and ignition switch is held at ON
position.

[Using SUZUKI scan tool]
1) Turn ignition switch OFF.
2) After setting cartridge to Suzuki scan tool, connect it to data link
connector (DLC) located on underside of instrument panel at
driver's seat side.
Special Tool
(A): 09931-76011 (Suzuki scan tool)
(B): Mass storage cartridge
(C): 09931-76030 (16 / 12 pin DLC adapter)
3) Turn ignition switch ON.
4) Read DTC according to instructions displayed on Suzuki scan
tool and print it or write it down. Refer to Suzuki scan tool opera-
tor's manual for further details.
NOTE:

When reading DTC stored in ECM / PCM using Suzuki scan
tool, select ªECMº from the applications menu and ªSU-
ZUKI modeº from the communication mode menu dis-
played on Suzuki scan tool.

If ECM / PCM detects a trouble in both electric fuel injec-
tion system and immobilizer control system, Suzuki scan
tool indicates trouble codes of both systems using Suzu-
ki mode of ECM application.
If communication between Suzuki scan tool and ECM / PCM is
not possible, check if Suzuki scan tool is communicable by con-
necting it to ECM / PCM in another vehicle. If communication is
possible in this case, Suzuki scan tool is in good condition. Then
check data link connector and serial data line (circuit) in the ve-
hicle with which communication was not possible.
5) After completing the check, turn ignition switch OFF and discon-
nect Suzuki scan tool from data link connector (DLC).

GLASS REMOVAL in this section.
2) Disconnect power window motor lead wire at coupler and loosen
clamp.
3) Loosen regulator mounting bolts, nuts and take out regulator
through hole as shown in left figure.
INSPECTION
1) Check regulator sliding and rotating parts for greasing.
2) Check rollers for wear and damage.
3) Check wire for damage.
INSTALLATION
Reverse removal procedure to install window regulator noting the
following point.

Tighten bolts and nuts according to the order (a, b, c / 1, 2, 3, 4)
shown in left figure.

When installing glass, check that the top part of the glass contacts
the glass run evenly and that the glass moves up and down
smoothly.
If the glass is tilted with respect to the glass run, make a fine ad-
justment with the screws.

Install door window regulator handle (if equipped) so that it has
an angle as shown in figure when glass is fully closed.

11) Check for water leakage by pouring water over windshield
through hose. If leakage is found, dry windshield and fill leaky
point with adhesive. If water still leaks even after that, remove
glass and start installation procedure all over again.
CAUTION:
Upon completion of installation, note the following.

Do not use high pressure water.

Do not blow compressed air directly at adhesive ap-
plied part when drying.

Do not use infrared lamp or like for drying.

Sudden closing of door before adhesive is completely
set may cause glass to become loose or to come off.
Therefore, if door is opened or closed before adhesive
is completely set, make sure to open all door glasses
and use proper care.

If molding is not securely in place, hold it down with
a tape until adhesive is completely set.

Each adhesive has its own setting time.
Be sure to refer to its maker's instruction, check set-
ting time of adhesive to be used and observe precau-
tions to be taken before adhesive is set.

Refrain from driving till adhesive is completely set so
as to ensure proper and sufficient adhesion.
