Servicing and Handling
WARNING!
Many of service procedures require
disconnection of “A/B” fuse and all air bag
(inflator) module(s) from initiator circuit to
avoid an accidental deployment.
Driver, Passenger, Side and Curtain Air Bag
(Inflator) Modules
• For handling and storage of a live air bag
(inflator) module, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module. When placing a live air bag
(inflator) module on a bench or other
surface, always face the bag up, away from
the surface. As the live passenger air bag
(inflator) module must be placed with its
bag (trim cover) facing up, place it on the
workbench with a slit (1) or use the
workbench vise (2) to hold it securely at its
lower mounting bracket (3). It is also
prohibited to place anything on top of the
trim cover and stack air bag (inflator)
modules. This is necessary so that a free
space is provided to allow the air bag to
expand in the unlikely event of accidental
deployment. Otherwise, personal injury
may result.
• Never dispose of live (undeployed) air bag
(inflator) modules (driver, passenger, side
and curtain). If disposal is necessary, be
sure to deploy them according to
deployment procedures described in “Air
Bag (Inflator) Module and Seat Belt
Pretensioner Disposal in Section 8B”
before disposal.
• The air bag (inflator) module immediately
after deployment is very hot. Wait for at
least half an hour to cool it off before
proceeding the work.• After an air bag (inflator) module has been
deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.

[A]: Always carry air bag (inflator) module with trim cover (air bag opening)
away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air
bag opening) up, away from loose objects.

Precautions for Installing Mobile
Communication Equipment
S6RW0D0000005
When installing mobile communication equipment such
as CB (Citizens-Band)-radio or cellular-telephone, be
sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic
control system.
• Keep the antenna as far away as possible from the
vehicle’s electronic control unit.
• Keep the antenna feeder more than 20 cm (7.9 in.)
away from electronic control unit and its wire
harnesses.
• Do not run the antenna feeder parallel with other wire
harnesses.
• Confirm that the antenna and feeder are correctly
adjusted.
Precaution for CAN Communication SystemS6RW0D0000006
• The loose (1) in the wire harnesses twist of the CAN
lines except around the connector (3) should be within
100 mm (3.9 in.). Refer to the wiring diagram for the
CAN lines discrimination. Excessively-loosed lines
may be influenced by the electric noise.
• Do not connect terminals of the CAN line using a
bypass wire (1). Otherwise, the CAN line may be
influenced by the electric noise.
Precautions for Electrical Circuit ServiceS6RW0D0000007
• When replacing a fuse, make sure to use a fuse of the
specified capacity. Use of a fuse with a larger capacity
will cause a damage to the electrical parts and a fire.
• When disconnecting and connecting coupler, make
sure to turn ignition switch OFF, or electronic parts
may get damaged.
• When disconnecting connectors, never pull the wiring
harness. Unlock the connector lock first and then pull
them apart by holding connectors themselves.

Precautions on Engine ServiceS6RW0D1100001
CAUTION!
The following information on engine service
should be noted carefully, as it is important in
preventing damage, and in contributing to
reliable engine performance.

• When raising or supporting engine for any reason, do
not use a jack under oil pan. Due to small clearance
between oil pan and oil pump strainer, jacking against
oil pan may cause it to be bent against strainer,
resulting in damaged oil pick-up unit.
• It should be kept in mind, while working on engine,
that 12-volt electrical system is capable of violent and
damaging short circuits.
When performing any work where electrical terminals
can be grounded, ground cable of the battery should
be disconnected at battery.
• Any time the air cleaner, throttle body or intake
manifold is removed, the intake opening should be
covered. This will protect against accidental entrance
of foreign material which could follow intake passage
into cylinder and cause extensive damage when
engine is started.
Precaution on On-Board Diagnostic (OBD)
System
S6RW0D1100006
There are two types of On-Board Diagnostic (OBD)
system, Euro OBD system and non-Euro-OBD system,
depending on the vehicle specification.
It is possible to identify each OBD system by checking if
it is equipped with the HO2S-2 or not.
• Euro OBD model is equipped with HO2S-2.
• Non-Euro-OBD model is not equipped with HO2S-2.
NOTE
For Taiwan model, bear in mind that it is non-
Euro-OBD model which is equipped with
HO2S-2.

As the diagnosis function is different between these two
types, be sure to fully understand the OBD system
referring to “On-Board Diagnostic System Description”.
OBD System Summary Table
Precautions in Diagnosing TroubleS6RW0D1100002
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on On-
Board Diagnostic (OBD) System”.

• Don’t disconnect ECM couplers from ECM, battery
cable from battery, ECM ground wire harness from
engine or main fuse before confirming diagnostic
information (DTC, freeze frame data, etc.) stored in
ECM memory. Such disconnection will erase
memorized information in ECM memory.
• Diagnostic information stored in ECM memory can be
cleared as well as checked by using SUZUKI scan
tool or CAN communication OBD generic scan tool.
Before using scan tool, read its Operator’s
(Instruction) Manual carefully to have good
understanding as to what functions are available and
how to use it.
For Euro OBD model, it is indistinguishable which
module turns on MIL because not only ECM but also
TCM (for A/T model) turns on MIL (for details of on-
board diagnostic system for A/T model, refer to “On-
Board Diagnostic System Description in Section 5A”
for A/T).
Therefore, check both ECM and TCM (for A/T model)
for DTC when MIL lights on.

• When checking ECM for DTC, keep in mind that DTC
is displayed on the scan tool as follows depending on
the scan tool used.
– SUZUKI scan tool displays DTC detected by ECM.
– CAN communication OBD generic scan tool
displays DTC detected by each of ECM and TCM
(for A/T model) simultaneously.
• Priorities for diagnosing troubles
If two or more DTCs are stored, proceed to the DTC
flow which has been detected earliest in the order and
follow the instruction in that flow.
If no instructions are given, troubleshoot DTCs
according to the following priorities.
a. DTCs other than DTC P0171 / P0172 (Fuel
system too lean / too rich), DTC P0300 / P0301 /
P0302 / P0303 / P0304 (Misfire detected) and
DTC P0401 / P0402 (EGR flow malfunction)
b. DTC P0171 / P0172 (Fuel system too lean / too
rich) and DTC P0401 / P0402 (EGR flow
malfunction)
c. DTC P0300 / P0301 / P0302 / P0303 / P0304
(Misfire detected)
• Be sure to read “Precautions for Electrical Circuit
Service in Section 00” before inspection and observe
what is written there.
• ECM replacement:
When substituting a known-good ECM, check for the
following conditions. Neglecting this check may cause
damage to a known-good ECM.
– Resistance value of all relays, actuators is as
specified respectively.
– MAP sensor, A/C refrigerant pressure sensor (if
equipped with A/C), accelerator pedal position
(APP) sensor and TP sensor are in good condition
and none of power circuits of these sensors is
shorted to ground.
• Communication of ECM, BCM, combination meter,
keyless start control module (if equipped with keyless
start control system), 4WD control module (if
equipped), TCM (for A/T model) and ABS control
module, is established by CAN (Controller Area
Network). (For more detail of CAN communication for
ECM, refer to “CAN Communication System
Description”). Therefore, handle CAN communication
line with care referring to “Precaution for CAN
Communication System in Section 00”.
• Immobilizer transponder code registration after
replacing ECM (Immobilizer model)
When ECM is replaced with new one or with another
one, make sure to register immobilizer transponder
code to ECM correctly according to “Procedure after
ECM Replacement in Section 10C”.Precautions for DTC TroubleshootingS6RW0D1100003
• Before performed trouble shooting, be sure to read
the “Precautions of ECM Circuit Inspection”.
• When measuring circuit voltage, resistance and/or
pulse signal at ECM connector, connect the special
tool to ECM and/or the ECM connectors referring to
“Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work,
perform “DTC Confirmation Procedure” and confirm
that the trouble has been corrected.
Precautions of ECM Circuit InspectionS6RW0D1100004
• ECM connectors are waterproofed. Each terminal of
the ECM connectors is sealed up with the grommet.
Therefore, when measuring circuit voltage, resistance
and/or pulse signal at ECM connector, do not insert
the tester’s probe into the sealed terminal at the
harness side. When measuring circuit voltage,
resistance and/or pulse signal at ECM connector,
connect the special tool to the ECM connectors. And,
insert the tester’s probe into the special tool’s
connectors at the harness side, and then measure
voltage, resistance and/or pulse signal. Or, ECM and
its circuits may be damaged by water.
• Wire colors of the special tool’s connectors are
different from the ones of the ECM connectors.
However, the circuit arrangement of the special tool’s
connectors is same as the one of the ECM
connectors. Therefore, measure circuit voltage and
resistance by identifying the terminal location subject
to the measurement.
Precautions of Electric Throttle Body System
Calibration
S6RW0D1100005
After performing one of works described below, it is
necessary to re-register the completely closed throttle
valve reference position stored in memory of ECM. (For
detailed information, refer to “Description of Electric
Throttle Body System Calibration”.) For the procedure to
register such data in ECM, refer to “Electric Throttle
Body System Calibration in Section 1C”.
• To shut off backup power of ECM for such purposes of
battery replacement or “DOME” fuse removal
• To erase DTCs P0122, P0123, P0222, P0223, P2101,
P2102, P2103, P2111, P2112, P2119 and/or P2135
• To replace ECM
• To replace throttle body and/or accelerator pedal
position (APP) sensor assembly

Downloaded from www.Manualslib.com manuals search engine 1A-12 Engine General Information and Diagnosis:
Operation Description
ECM (5) detects opening (depressed extent of pedal) of the accelerator pedal based on signal voltage of the APP
sensor (1) and using that data and engine operation condition, it calculates the optimum throttle valve opening. On the
other hand, it detects the throttle valve opening based on the signal voltage of the throttle position sensor (3) included
in the throttle body (2) and compares it with the above calculated optimum throttle valve opening. When there is a
difference between them, ECM controls the duty ratio (100% – 0%) according to this difference to drive the throttle
actuator (motor) (4) included in the throttle body. When there is no difference, ECM controls the duty ratio to about
15% to maintain the throttle valve opening. In this way, the throttle valve (17) is opened and closed to achieve the
optimum throttle valve opening.
In this system, as the throttle position sensor and APP sensor have 2 sensors (main and sub) each, highly accurate
and highly reliable control and abnormality detection are assured. Also, when ECM detects an abnormality in the
system, it turns off the throttle actuator control relay (8) to stop controlling the throttle actuator. When the throttle
actuator control relay is turned off, the throttle valve is fixed at the opening of about 7° from its completely closed
position (default opening) by the force of the return spring and open spring included in the throttle body.
This throttle body is not equipped with IAC valve for idle speed control. Idle speed control is done by the throttle
actuator which opens/closes the throttle valve.
Electronic Control System Description
The electronic control system consists of 1) various
sensors which detect the state of engine and driving
conditions, 2) ECM which controls various devices
according to the signals from the sensors and 3) various
controlled devices.
Functionally, it is divided into the following sub systems:
• Fuel injection control system
• Ignition control system
• Electric throttle body control system
• Fuel pump control system
• Radiator cooling fan control system
• Evaporative emission control system
• EGR system (if equipped)
• Oxygen sensor heater control system• A/C control system (if equipped with A/C)
• Camshaft position control system
• Immobilizer control system
• Controller (computer) communication system
Especially, ECM (Engine Control Module), BCM (Body
electrical Control Module), combination meter, ABS /
control module, keyless start control module (if equipped
with keyless start control system), TCM (Transmission
Control Module) (for A/T model) and 4WD control
module (if equipped) intercommunicate by means of
CAN (Controller Area Network) communication.

I6RW0D110014-01

Downloaded from www.Manualslib.com manuals search engine 1A-26 Engine General Information and Diagnosis:
• The MIL is turned on when the ECM and/or
TCM detect malfunction(s). Each ECM and
TCM stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the scan tool because the
DTC stored in ECM and TCM is not read
and displayed at a time. However, each of
the ECM and TCM needs not to be checked
with the generic scan tool because the
DTC stored in ECM and TCM is read and
displayed at a time.

1) Prepare CAN communication OBD generic scan tool
or SUZUKI scan tool.
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
2) With ignition switch OFF, connect it to DLC (1)
located on underside of instrument panel at driver’s
seat side.
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC and freeze frame data according to
instructions displayed on scan tool and print them or
write them down. Refer to scan tool operator’s
manual for details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
5) After completing the check, turn ignition switch off
and disconnect scan tool from DLC.
DTC ClearanceS6RW0D1104004
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on On-
Board Diagnostic (OBD) System”.

1) Connect SUZUKI scan tool or CAN communication
OBD generic scan tool to data link connector in the
same manner as when making this connection for
DTC check.2) Turn ignition switch OFF and then ON.
3) Erase DTC and pending DTC according to
instructions displayed on scan tool. Freeze frame
data is cleared with the DTC. Refer to scan tool
operator’s manual for further details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
4) After completing the clearance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
NOTE
DTC and freeze frame data stored in ECM
memory are also cleared in the following
cases. Be careful not to clear them before
keeping their record.
• When power to ECM is cut off (by
disconnecting battery cable, removing
fuse or disconnecting ECM connectors).
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles. (See “Warm-Up Cycle” of “On-
Board Diagnostic System Description”.)

Troubleshooting for Communication Error with
Scan Tool Using CAN
S6RW0D1104083
Perform this troubleshooting when it is not possible to
communicate between scan tool and ECM/TCM.
NOTE
• When performing this troubleshooting, be
sure to have full understanding of
“Precaution on CAN Troubleshooting” and
observe it.
• It may be possible that CAN system has
trouble because of fuse blown or low
battery voltage. Before troubleshooting,
check to make sure that fuse, battery
voltage and generator status are normal.
• When disconnecting each control module

Malfunction Indicator Lamp Does Not Come ON with Ignition Switch ON and Engine Stop (but
Engine Can Be Started)
S6RW0D1104011
Wiring Diagram
Circuit Description
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM
being supplied with the main power, transmits indication ON signal of malfunction indicator lamp (MIL) to combination
meter in order to turn MIL ON. And then, combination meter turns MIL ON. When the engine starts to run and no
malfunction is detected in the system, ECM transmits MIL indication OFF signal to combination meter in order to turn
MIL OFF. And then, combination meter turns MIL OFF, but if a malfunction was or is detected, MIL remains ON even
when the engine is running.
