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)

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.

DTC ClearanceS7RS0B1104004
NOTE
There are two types of OBD system
depending on the vehicle specification.
For details, refer to “Precaution on On-Board
Diagnostic (OBD) System”.

Using Scan Tool1) Connect OBD generic scan to ol or SUZUKI 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. Refer to scan
tool operator’s manual for further details.
4) After completing the clear ance, 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”.)

Without Using Scan Tool (Hong Kong Model)
1) Turn ignition switch to OFF position.
2) Disconnect battery negative cable for specified time below to erase diagnostic trouble code stored in
ECM memory and reconnect it.
