Precautions
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.

Data Link Connector (DLC)S6RW0D1101011
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on On-
Board Diagnostic (OBD) System”.

DLC (1) is in compliance with SAE J1962 in the shape of
connector and pin assignment.
OBD CAN Hi line (6) and Low line (3) (CAN line of ISO
15765-4) are used for SUZUKI scan tool (SUZUKI-SDT)
(7) or CAN communication OBD generic scan tool to
communicate with ECM (included in immobilizer control)
and TCM (Transmission Control Module) (for A/T
model).
Engine and Emission Control System
Description
S6RW0D1101004
The engine and emission control system is divided into 4
major sub-systems: air intake system, fuel delivery
system, electronic control system and emission control
system.
Air intake system includes air cleaner, throttle body and
intake manifold.
Fuel delivery system includes fuel pump, delivery pipe,
etc.
Electronic control system includes ECM, various sensors
and controlled devices.
Emission control system includes EGR, EVAP and PCV
system.

Air Intake System DescriptionS6RW0D1101006
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 combustion 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 System CalibrationS6RW0D1101007
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 differences 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 saved 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 “Precautions of Electric Throttle Body System Calibration” is
performed.
Also, after replacement of the throttle body and/or APP sensor assembly, 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 registration of the completely closed throttle valve position.
If the engine is started during this registration process, such symptom as “longer cranking time” 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.)
Description of Electric Throttle Body SystemS6RW0D1101009
The Electric Throttle Body System consists of electric throttle body assembly, accelerator pedal position (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 pedal, 2 accelerator position sensors
