• 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-Vehicl e 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 re nder 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 av oid unintended air bag system activation.
 Do not modify the steering wheel, instrument pa nel or any other air bag system component on or
around air bag system components or wiring. Modi fications 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, th at is air bag (inflator) modules, SDM and/or seat
belt with pretensioner, beforehand to avoid component damage or unintended activation.

Downloaded from www.Manualslib.com manuals search engine 1A-2 Engine General Information and Diagnosis:
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• ECM replacement: When substituting a known-good ECM, check for the
following conditions. Neglec ting 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 and TP sensor are in good condition and none of power
circuits of these sensors is shorted to ground.
• Communication of ECM, BCM, ABS/ESP ® control
module, combination meter, keyless start control
module, steering angle sensor (ESP ® model) and
TCM (A/T model), is esta blished 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
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 of ECM Circuit InspectionS7RS0B1100003
• ECM connectors are waterproofed. Each terminal of the ECM connectors is sealed up with the grommet.
Therefore, when measuring ci rcuit voltage, resistance
and/or pulse signal at ECM connector, do not insert
the tester’s probe into th e 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
S7RS0B1100004
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, P01 23, P0222, P0223, P2101,
P2102, P2103, P2111, P2112, P2113, P2119, P2123,
P2127, P2128, P2135 and/or P2138
• To replace ECM
• To replace throttle body and/or accelerator pedal position (APP) sensor assembly
General Description
Statement on Cleanliness and CareS7RS0B1101001
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the thousands of an
millimeter (ten thous ands of an inch).
Accordingly, when any internal engine parts are
serviced, care and cleanliness are important.
It should be understood that proper cleaning and
protection of machined surfaces and friction areas is part
of the repair procedure. This is considered standard
shop practice even if not specifically stated.
• A liberal coating of engine oil should be applied to friction areas during assembly to protect and lubricate
the surfaces on initial operation. • Whenever valve train components, pistons, piston
rings, connecting rods, rod bearings, and crankshaft
journal bearings are removed for service, they should
be retained in order.
At the time of installation, they should be installed in
the same locations and with the same mating
surfaces as when removed.
• Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to
wire harness or other electrical parts.

CAN communication system uses the serial communication in which data is transmitted at a high speed. It uses a
twisted pair of two communication lines for the high-speed da ta transmission. As one of its characteristics, multiple
control modules can communicate simultaneously. In addition, it has a function to detect a communication error
automatically. Each module reads necessary data from the received data and transmits data. ECM communicates
control data with each control module as follows.
ECM Transmission Data
NOTE
• In communication between ECM and combination meter and between ECM and steering angle sensor (ESP ® model), data is transmitted only from ECM to combination meter and steering angle
sensor. (Combination meter and steering angle sensor does not transmit data to ECM.)

Air Intake System DescriptionS7RS0B1101006
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), electric throttle body (3)
(for the details, refer to “Description of Electric Throttle Body System”.), and intake manifold (4).
The air (by the amount corresponding to throttle valve (5) opening and engine speed) is filtered by the air cleaner,
distributed by the intake, and finally drawn into each combusti on chamber. Electric throttle body is not equipped with
IAC valve for idle speed control. Idle speed control is done by the throttle actuator (6) which opens/closes the throttle
valve. (For the details, refer to “Description of Electric Throttle Body System”).
Description of Electric Throttle Body SystemS7RS0B1101007
The Electric Throttle Body System consists of electric throttle body asse mbly, APP sensor assembly, ECM and throttle
actuator control relay.
Among them, assembly components are as follows.
• Electric throttle body assembly: throttle valve, throttle actuator, 2 throttle position sensors
• APP sensor assembly: Accelerator pe dal, 2 accelerator position sensors
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 engi ne 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 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 th ere 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 thrott le 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 th rottle actuator control relay (8) to step controlling the throttle actuator.
When the throttle actuator control relay is turned off, the throttle valve is fixed at the specified opening below from its
completely closed position (default openin g) 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.

Description of Electric Throttle Body System CalibrationS7RS0B1101008
ECM calculates controlled opening of the throttle valve on the basis of the completely closed throttle valve position of
the electric throttle body system. The completely closed position data is saved in memory of ECM. However, the
completely closed position of the throttle valve of the electric throttle body system (signal voltage from throttle position
sensor when throttle is completely closed) differs one from the other depending on individual differences of the throttle
valve and throttle position sensor. As such individual diff erences must be taken into account for controlling the throttle
valve, it is necessary to register the completely closed throttle valve position data in ECM. When such data is
registered in ECM, it is sa ved in RAM (memory) of ECM and used as the base data for controlling the throttle valve.
This data is cleared, when any of the works described in “Preca utions of Electric Throttle Body System Calibration” is
performed.
Also, after replacement of the throttle body and/or APP sensor , the completely closed position data in memory of ECM
must be cleared once and a new one must be registered, or ECM cannot judge the complete closure position properly.
For the procedure to register such data, refer to “Electric Throttle Body System Calibration in Section 1C”. (After the
completely closed position data is cleared , ECM, for the first time only, opens and closes the throttle valve for about 5
seconds after the ignition switch is turned ON position, for re gistration of the completely closed throttle valve position.
If the engine is started during this registration process, such symptom as “longe r cranking” or “slow rise of revolution
speed immediately after start-up” may occur. However, turning OFF the ignition switch once and restarting will set
correct registration.)
