• When disconnecting vacuum hoses, attach a tag  describing the correct installation positions so that the 
hoses can be reinstalled correctly.
• After servicing fuel, oil, coolant, vacuum, exhaust or  brake systems, check all lin es related to the system 
for leaks. • For vehicles equipped with fuel injection systems, 
never disconnect the fuel line between the fuel pump 
and injector without first releasing the fuel pressure, or 
fuel can be sprayed out under pressure.
• When performing a work that produces a heat  exceeding 80  °C (176 ° F) in the vicinity of the 
electrical parts, remove t he heat sensitive electrical 
part(s) beforehand.
• Use care not to expose connectors and electrical  parts to water which will  be a cause of a trouble.
• Always be careful not to handle electrical parts  (computer, relay, etc.) in a rough manner or drop 
them.

Short Circuit Check (Wire Harness to Ground)1) Disconnect negative (–) cable at battery.
2) Disconnect connectors at bot h ends of the circuit to 
be checked.
NOTE
If the circuit to be checked is connected to 
other parts (1), disconnect all connectors of 
those parts.
Otherwise, diagnosis will be misled.
 
3) Measure resistance between terminal at one end of  circuit (“A-1” terminal in the figure) and body ground. 
If continuity is indicated, it  means that there is a short 
to ground between terminals “A-1” and “C-1” of the 
circuit. 4) Disconnect the connector included in circuit 
(connector-B) and measure resistance between “A-
1” and body ground. If continuity is indicated, it 
means that the circuit is  shorted to the ground 
between terminals “A-1” and “B-1”.
Intermittent and Poor Connection InspectionS7RS0B0006002
Most intermittent are caused by faulty electrical 
connections or wiring, although a sticking relay or 
solenoid can occasionally be at fault. When checking it 
for proper connection, perfor m careful check of suspect 
circuits for:
• Poor mating of connector halves, or terminals not fully  seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must  be clean and free of any foreign material which could 
impede proper terminal contact. However, cleaning 
the terminal with a sand paper or the like is prohibited. 
• Damaged connector body, exposing the terminals to  moisture and dirt, as well  as not maintaining proper 
terminal orientation with the component or mating 
connector.

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,

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.

Non-Euro-OBD
ECM diagnosis troubles which may occur in the area 
including the following parts w hen the ignition switch is 
ON and the engine is running, and indicates the result by 
turning on or flashing malfunction indicator lamp (1).
• Heated oxygen sensor
• ECT sensor
•TP sensor
• APP sensor
• MAF sensor
• IAT sensor
• MAP sensor
• CMP sensor
• CKP sensor
• Knock sensor
• Wheel speed sensor (VSS)
• CPU (Central Processing Unit) of ECM
• Oil control valve
• EGR valve
• EVAP canister purge valve
• Ignition coil
• Starter relay
• Radiator fan relay
• CAN communication
• Barometric pressure sensor
• ECM back up power supply
ECM and malfunction indicator lamp (1) operate as 
follows.
• Malfunction indicator lamp (1) lights when the ignition  switch is turned ON (but t he engine at stop) with the 
diagnosis switch terminal ungrounded regardless of 
the condition of Engine and Emission control system. 
This is only to check the ma lfunction indicator lamp (1) 
in the combination meter and its circuit.
• If the above areas of Engine and Emission control  system is free from any trouble after the engine start 
(while engine is running), malfunction indicator lamp 
(1) turns OFF. • When ECM detects a trouble which has occurred in 
the above areas, it makes malfunction indicator lamp 
(1) turn ON while the engi ne is running to warn the 
driver of such occurrence of trouble and at the same 
time it stores the trouble area in ECM back-up 
memory. (The memory is kept as it is even if the 
trouble was only temporary and disappeared 
immediately. And it is not erased unless the power to 
ECM is shut off for specified  time or it is cleared by 
SUZUKI scan tool (2).)
For Hong Kong model, DTC can be read by not only 
using SUZUKI scan tool but also displayed on 
odometer (5) of the combination meter. (i.e. when 
diagnosis switch terminal (3) is grounded with a 
service wire (4) and ignition  switch is turned ON.) For 
further detail of the checking procedure, refer to “DTC 
Check”.

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.)
