WARNING!
SDM
• For handling and storage of a SDM, select
a place where the ambient temperature
below 65 °C (150 °F), without high humidity
and away from electric noise.
• During service procedures, be very careful
when handling a Sensing and Diagnostic
Module (SDM). Never strike or jar the SDM.
• Never power up the air bag system when
the SDM is not rigidly attached to the
vehicle. All SDM and mounting bracket
fasteners must be carefully torqued and
the arrow must be pointing toward the
front of the vehicle to ensure proper
operation of the air bag system.
The SDM could be activated when powered
while not rigidly attached to the vehicle
which could cause deployment and result
in personal injury.

WARNING!
Driver and Passenger Seat Belt
Pretensioners
• For handling and storage of a live seat belt
pretensioner, select a place where the
ambient temperature below 65 °C (150 °F),
without high humidity and away from
electric noise.
• Never carry seat belt pretensioner by wire
or connector of pretensioner. When
placing a live seat belt pretensioner on the
workbench or some place like that, never
put something on seat belt pretensioner.
Otherwise, personal injury may result.
• Never dispose of live (inactivated) seat belt
pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” before disposal.
• The seat belt pretensioner immediately
after activation is very hot. Wait for at least
half an hour to cool it off before
proceeding the work.
• With many service procedures, gloves and
safety glasses should be worn to prevent
any possible irritation of the skin or eyes.

• Even when the accident was light enough not to
cause air bags to activate, be sure to inspect system
parts and other related parts according to instructions
under “Repair and Inspection Required after Accident
in Section 8B”.
• When servicing parts other than air bag system, if
shocks may be applied to air bag system component
parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver,
passenger, side and curtain), seat belt pretensioners
(driver and passenger), forward sensor, side sensors
or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied, never attempt
disassembly or repair but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got
onto air bag (inflator) modules (driver, passenger, side
and curtain) or seat belt pretensioners (drive and
passenger), wipe off immediately with a dry cloth.
• Air bag wire harness is included in floor and
instrument panel wire harnesses. Air bag wire
harness branched off from floor and instrument panel
wire harnesses can be identified easily as it is covered
with a yellow protection tube and it has yellow
connectors. Be very careful when handling it.
• When an open in air bag wire harness, damaged wire
harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• Do not apply power to the air bag system unless all
components are connected or a diagnostic flow
requests it, as this will set a DTC.
• Never use air bag system component parts from
another vehicle.
• When using electric welding, be sure to disconnect all
air bag (inflator) module connectors and pretensioner
connectors from air bag wire harness respectively.
• Never expose air bag system component parts
directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each
part of air bag system components. Be sure to follow
the instructions.
• After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check in Section 8B”.

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.)

Downloaded from www.Manualslib.com manuals search engine 1A-26 Engine General Information and Diagnosis:
• The MIL is turned on when the ECM and/or
TCM detect malfunction(s). Each ECM and
TCM stores diagnostic information as the
diagnostic trouble code (DTC) in its
memory and outputs the DTC to the scan
tool.
Therefore, check both of the ECM and TCM
for any DTC with the scan tool because the
DTC stored in ECM and TCM is not read
and displayed at a time. However, each of
the ECM and TCM needs not to be checked
with the generic scan tool because the
DTC stored in ECM and TCM is read and
displayed at a time.

1) Prepare CAN communication OBD generic scan tool
or SUZUKI scan tool.
Special tool
(A): SUZUKI scan tool (SUZUKI-SDT)
2) With ignition switch OFF, connect it to DLC (1)
located on underside of instrument panel at driver’s
seat side.
3) Turn ignition switch ON and confirm that MIL lights.
4) Read DTC and freeze frame data according to
instructions displayed on scan tool and print them or
write them down. Refer to scan tool operator’s
manual for details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
5) After completing the check, turn ignition switch off
and disconnect scan tool from DLC.
DTC ClearanceS6RW0D1104004
NOTE
There are two types of OBD system
depending on the vehicle specification.
For identification, refer to “Precaution on On-
Board Diagnostic (OBD) System”.

1) Connect SUZUKI scan tool or CAN communication
OBD generic scan tool to data link connector in the
same manner as when making this connection for
DTC check.2) Turn ignition switch OFF and then ON.
3) Erase DTC and pending DTC according to
instructions displayed on scan tool. Freeze frame
data is cleared with the DTC. Refer to scan tool
operator’s manual for further details.
If communication between scan tool and ECM is not
possible, go to “Troubleshooting for Communication
Error with Scan Tool Using CAN”.
4) After completing the clearance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
NOTE
DTC and freeze frame data stored in ECM
memory are also cleared in the following
cases. Be careful not to clear them before
keeping their record.
• When power to ECM is cut off (by
disconnecting battery cable, removing
fuse or disconnecting ECM connectors).
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles. (See “Warm-Up Cycle” of “On-
Board Diagnostic System Description”.)

Troubleshooting for Communication Error with
Scan Tool Using CAN
S6RW0D1104083
Perform this troubleshooting when it is not possible to
communicate between scan tool and ECM/TCM.
NOTE
• When performing this troubleshooting, be
sure to have full understanding of
“Precaution on CAN Troubleshooting” and
observe it.
• It may be possible that CAN system has
trouble because of fuse blown or low
battery voltage. Before troubleshooting,
check to make sure that fuse, battery
voltage and generator status are normal.
