Precautions
Precautions on Engine ServiceS7RS0B1100001
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 syste m 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
S7RS0B1100005
There are two types of On -Board Diagnostic (OBD)
system, Euro OBD system and non-Euro-OBD system,
depending on the vehicle specification.
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 TroubleS7RS0B1100002
NOTE
There are two types of OBD system
depending on the vehicle specification.
For details, refer to “Precaution on On-Board
Diagnostic (OBD) System”.

• Don’t disconnect 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 checke d by using SUZUKI scan
tool or 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 (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”).
Therefore, check both ECM and TCM (A/T model) for
DTC when MIL lights on.
When checking ECM for DTC, keep in mind that DTC
is displayed on the scan tool as follows depending on
the scan tool used.
– SUZUKI scan tool displays DTC detected by ECM.
– OBD generic scan tool displays DTC detected by each of ECM and TCM (A/T model) simultaneously.
• Priorities for diagnosing troubles If two or more DTCs are stored, proceed to the DTC
flow which has been detected earliest in the order and
follow the instructi on in that flow.
If no instructions are given, troubleshoot DTCs
according to the following priorities.
a. DTCs other than DTC P0171 / P0172 (Fuel system too lean / too rich), DTC P0300 / P0301 /
P0302 / P0303 / P0304 (Misfire detected) and
DTC P0401 / P0402 (EGR flow malfunction)
b. DTC P0171 / P0172 (Fuel system too lean / too rich) and DTC P0401 / P0402 (EGR flow
malfunction)
c. DTC P0300 / P0301 / P0302 / P0303 / P0304 (Misfire detected)

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,
P2102, P2103, P2111, P2112, P2113, P2119, P2123,
P2127, P2128, P2135 and/or P2138
• To replace ECM
• To replace throttle body and/or accelerator pedal position (APP) sensor assembly
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.

Generator Control System DescriptionS7RS0B1101010
Generator Control System consists of a generator (1), electric load current sensor (7) located in the main fuse box (4)
and ECM (5).
ECM controls generated electricity (adjusting voltage of IC regulator (2)) so that it is suitable for the engine and electric
load conditions. When the electric load increases quickly, generation load of the generator increases quickly and
causes idling to change. To prevent this, ECM makes generated electricity volume vary gradually to stabilize idling.
Also, it reduces the engine load caused by temporary incr ease in electricity generation to cope with the engine
condition (such as when accelerating).
Operation
ECM controls the generated voltage of the generator using “C” terminal (generator control terminal) duty, based on
following information.
• Engine condition (ECT, vehicle speed, engine speed, TP, etc.) (9)
• Battery voltage (ECM backup power voltage) (10)
• Electric load condition (blower motor, rear defogger, head lights, radiator fan, A/C, etc.) (11)
• “FR” terminal output (field coil (3) cont rol duty) which indicates the operation rate (electricity generation condition) of
the generator.
Then the generator uses “C” terminal duty to regulate the adju sting voltage of the IC regulator with the field coil control
duty so as to control its generated voltage (“B” terminal output voltage).
(For more information of the generated voltage, refer to “Charging System Specifications in Section 1J”.)
Furthermore, the generation condition of the generator is co ntrolled to the optimum level by the electric load current
sensor (7) which detects the electrical load condition (cur rent consumption) linearly even when a sudden electrical
load variation occurs and thus the engine load is reduced.
