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.

• 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 low battery voltage will lead
to erroneous diagnosis.Air Bag WarningS6RW0D0000008

General Description
Statement on Cleanliness and CareS6RW0D1101001
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 thousands 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.
• 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 DescriptionS6RW0D1101002
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, 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 DescriptionS6RW0D1101003
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, 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 instrument 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 continuously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL (1) turn OFF although DTC stored in its
memory will remain.)

Priority of freeze frame data:
ECM has 4 frames where the freeze frame data can be stored. The first frame stores the freeze frame data of the
malfunction which was detected first. However, the freeze frame data stored in this frame is updated according to the
priority described. (If malfunction as described in the upper square “1” is detected while the freeze frame data in the
lower square “2” has been stored, the freeze frame data “2” will be updated by the freeze frame data “1”.)
In the 2nd through the 4th frames, the freeze frame data of each malfunction is stored in the order as each malfunction
is detected. These data are not updated.
Shown in the table are examples of how freeze frame data are stored when two or more malfunctions are detected.
Freeze frame data clearance:
The freeze frame data is cleared at the same time as clearance of DTC.
Non-Euro-OBD Model
ECM diagnosis troubles which may occur in the area
including the following parts when the ignition switch is
ON and the engine is running, and indicates the result by
turning on malfunction indicator lamp (MIL) (1).
• Heated oxygen sensor-1
• Heated oxygen sensor-2
• ECT sensor
•TP sensor
• Throttle actuator
• MAF sensor
• IAT sensor
• CMP sensor
• CKP sensor
• Knock sensor
• Wheel speed sensor
• CPU (Central Processing Unit) of ECM
• APP sensor
• Oil control valve (VVT model)
• Barometric pressure sensor
• A/C refrigerant pressure sensor
• ECM backup power supply
• Fuel level sensor
•CANECM and MIL operate as follows.
• MIL lights when the ignition switch is turned ON (but
the engine at stop) with the diagnosis switch terminal
ungrounded regardless of the condition of Engine and
Emission control system. This is only to check MIL 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), MIL turns OFF.
• When ECM detects a trouble which has occurred in
the above areas, it makes MIL turn ON while the
engine 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
(SUZUKI-SDT) (2).)
For further detail of the checking / clearing procedure,
refer to “DTC Check” or “DTC Clearance”. Priority Freeze frame data in frame 1
