Downloaded from www.Manualslib.com manuals search engine 00-9 Precautions: 
• Be careful not to touch the electrical terminals of parts which use microcomputers (e.g. electronic control unit 
like as ECM, PCM, P/S controller, etc.). The static 
electricity from your body  can damage these parts.
• Never connect any tester (voltmeter, ohmmeter, or  whatever) to electronic control unit when its coupler is 
disconnected. Attempt to do it may cause damage to 
it.
• Never connect an ohmmeter to electronic control unit  with its coupler connected to  it. Attempt to do it may 
cause damage to electronic control unit and sensors.
• Be sure to use a specified voltmeter / ohmmeter.  Otherwise, accurate measurements may not be 
obtained or personal injury ma y result. If not specified, 
use a voltmeter with high impedance (M  Ω/V 
minimum) or a digital type voltmeter.
• When taking measurements at electrical connectors  using a tester probe, be sure to insert the probe (2) 
from the wire harness side (backside) of the 
connector (1). • When connecting meter probe (2) from terminal side 
of coupler (1) because it can’t be connected from 
harness side, use extra care not to bend male 
terminal of coupler of force its female terminal open 
for connection.
In case of such coupler as shown connect probe as 
shown to avoid opening female terminal.
Never connect probe where male terminal is 
supposed to fit.
• When checking connection  of terminals, check its 
male half for bend and female half for excessive 
opening and both for locking (looseness), corrosion, 
dust, etc.
• Before measuring voltage at each terminal, check to  make sure that battery voltage is 11 V or higher. Such 
terminal voltage check at lo w battery voltage will lead 
to erroneous diagnosis.

• When testing with any of the following equipments 
(when vehicle is tested by  rotating wheels (tires) 
under vehicle stop), be sure to deactivate ESP ® 
system referring to “Precautions in Speedometer Test 
or Other Tests in Section 4F” to obtain correct data.
– 2 or 4-wheel chassis dynamometer
– Speedometer tester
– Brake tester
–Etc.
ESP ® control module
• When ESP ® control module is removed / installed, do 
not use impact wrenches which generate shock or 
impact to avoid damaging sensors in ESP ® control 
module.
• When any of the following operation is done, calibrate  steering angle sensor referring to “Sensor Calibration 
in Section 4F”.
– When battery or dome fuse is removed.
– When steering angle sensor is replaced.
Brake CautionS7RS0B0000014
CAUTION! 
All brake fasteners are important attaching 
parts in that they could affect the 
performance of vital parts and systems, and/
or could result in major repair expense. They 
must be replaced with one of same part 
number or with an eq uivalent part if 
replacement becomes necessary. Do not use 
a replacement part of lesser quality or 
substitute design. Torque values must be 
used as specified during reassembly to 
assure proper retention of all parts. There is 
to be no welding as it may result in extensive 
damage and weakening of the metal.
 
Repair Instructions
Electrical Circuit Inspection ProcedureS7RS0B0006001
While there are various electrical circuit inspection 
methods, described here is a general method to check 
its open and short circuit by using an ohmmeter and a 
voltmeter.
Open Circuit Check
Possible causes for the open  circuit are as follows. As 
the cause is in the connector or terminal in many cases, 
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due  to dirt, corrosion or rust 
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic 
control unit such as ECM, TCM, ABS control module, 
etc., it is important to perfor m careful check, starting with 
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit  being checked for loose connection. Also check lock 
condition of connector if equipped with connector 
lock. 3) Using a test male terminal
, check both terminals of 
the circuit being checked for contact tension of its 
female terminal. Check each  terminal visually for 
poor contact (possibly caused  by dirt, corrosion, rust 
entry of foreign object, etc.). At the same time, check 
to make sure that each te rminal is locked in the 
connector fully.
1. Check contact tension by inserting and removing just for once.

There are two kinds of colored wire used in this vehicle. One is single-colored wire and the other is dual-colored 
(striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color sy mbols (i.e. “GRN/YEL”). The first symbo l represents the base color of the wire 
(“GRN” in the figure) and the second symbol represents  the color of the stripe (“YEL” in the figure).
Fasteners InformationS7RS0B0101004
Metric Fasteners
Most of the fasteners used for this vehicle are JIS-
defined and ISO-defined metric fasteners. When 
replacing any fasteners, it is most important that 
replacement fasteners be the correct diameter, thread 
pitch and strength.
CAUTION! 
Even when the nominal diameter (1) of thread 
is the same, the thread pitch (2) or the width 
across flats (3) may vary between ISO and 
JIS. Refer to JIS-TO-ISO Main Fasteners 
Comparison Table below for the difference.
Installing a mismatched bolt or nut will cause 
damage to the thread.
Before installing, check the thread pitch for 
correct matching and then tighten it by hand 
temporarily. If it is tight, recheck the thread 
pitch.
 
JIS-TO-ISO Main Fasteners Comparison Table Fastener Strength Identification
Most commonly used metric fastener strength property 
classes are 4T, 6.8, 7T, 8.8 and radial line with the class 
identification embossed on the head of each bolt. Some 
metric nuts will be marked with punch, 6 or 8 mark 
strength identification on the nut face. Figure shows the 
different strength markings.
When replacing metric fasteners, be careful to use bolts 
and nuts of the same strength or greater than the original 
fasteners (the same number marking or higher). It is 
likewise important to select replacement fasteners of the 
correct diameter and thread 
pitch. Correct replacement 
bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks 
correspond to bolt strength (increasing numbers 
represent increasing strength).

• 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”.

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.  
Page 53 of 1496
Downloaded from www.Manualslib.com manuals search engine Engine General Information and Diagnosis:  1A-3
• The four cylinders of the engine are identified by numbers; No.1 (1), No.2 (2 ), No.3 (3) and No.4 (4) 
counted from crankshaft pulley side to flywheel side.
Engine Diagnosis General DescriptionS7RS0B1101002
NOTE
There are two types of OBD system 
depending on the vehicle specification.
For details, refer to “Precaution on On-Board 
Diagnostic (OBD) System”.
 
This vehicle is equipped with an engine and emission 
control system which are under control of ECM.
The engine and emission control system in this vehicle 
are controlled by ECM. ECM has an On-Board 
Diagnostic system which detects a malfunction in this 
system and abnormality of those parts that influence the 
engine exhaust emission. When diagnosing engine 
troubles, be sure to have full  understanding of the outline 
of “On-Board Diagnostic System Description” and each 
item in “Precautions in Diagnosing Trouble” and execute 
diagnosis according to “Engine and Emission Control 
System Check”.
There is a close relationship between the engine 
mechanical, engine cooling system, ignition system, 
exhaust system, etc. and  the engine and emission 
control system in their structure and operation. In case of 
an engine trouble, even when  the malfunction indicator 
lamp (MIL) doesn’t turn ON, it should be diagnosed 
according to “Engine and Emission Control System 
Check”.
On-Board Diagnostic System DescriptionS7RS0B1101003
NOTE
There are two types of OBD system 
depending on the vehicle specification.
For details, refer to “Precaution on On-Board 
Diagnostic (OBD) System”.
 
Euro OBD Model
ECM in this vehicle has the following functions.
• When the ignition switch is turned ON with the engine  at a stop, malfunction indicator lamp (MIL) (1) turns 
ON to check the circuit of the malfunction indicator 
lamp (1). • When ECM detects a malfunction which gives an 
adverse effect to vehicle emission while the engine is 
running, it makes the malfunction indicator lamp (1) in 
the meter cluster of the inst rument panel turn ON or 
flash (flashing only when  detecting a misfire which 
can cause damage to the catalyst) and stores the 
malfunction area in its memory.
(If it detects that contin uously 3 driving cycles are 
normal after detecting a malfunction, however, it 
makes MIL (1) turn OFF although DTC stored in its 
memory will remain.)
• As a condition for detecting a malfunction in some  areas in the system being monitored by ECM and 
turning ON the malfunction indicator lamp (1) due to 
that malfunction, 2 driving cycle detection logic is 
adopted to prevent erroneous detection.
• When a malfunction is detected, engine and driving  conditions then are stored in ECM memory as freeze 
frame data. (For the details, refer to description on 
“Freeze Frame Data”.)
• It is possible to communicate by using not only  SUZUKI scan tool (2) but also OBD generic scan tool. 
(Diagnostic information can be accessed by using a 
scan tool.)
Warm-Up Cycle
A warm-up cycle means sufficie nt vehicle operation such 
that the coolant temperature has risen by at least 22  °C 
(40  °F) from engine starting and reaches a minimum 
temperature of 70  °C (160 ° F).

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”.
