6-4 ENGINE GENERAL INFORMATION AND DIAGNOSIS
GENERAL INFORMATION
STATEMENT ON CLEANLINESS AND CARE
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.
Throughout this section, 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 jour-
nal 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.
Throughout this manual, 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.
GENERAL INFORMATION ON ENGINE SERVICE
THE FOLLOWING INFORMATION ON ENGINE SERVICE SHOULD BE NOTED CAREFULLY, AS IT IS
IMPORTANT IN PREVENTING DAMAGE, AND IN CONTRIBUTING TO RELIABLE ENGINE PERFOR-
MANCE.
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 result-
ing in damaged oil pick-up unit.
It should be kept in mind, while working on engine, that 12-volt electrical system 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 cylin-
der and cause extensive damage when engine is started.

Freeze Frame Data Clearance :
The freeze frame data is cleared at the same time as clearance of
diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC (1) is in compliance with SAEJ1962 in its installation posi-
tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) is used for SUZUKI scan tool
(Tech-1) or generic scan tool to communicate with ECM, TCM,
ABS control module and Air bag SDM.
SUZUKI serial data line is used for SUZUKI scan tool (Tech -1) to
communicate with immobilizer control module.FRAME

6-16 ENGINE GENERAL INFORMATION AND DIAGNOSIS
[Without Using SUZUKI Scan Tool] (Vehicle without Immo-
bilizer Indicator Lamp)
1) Check malfunction indicator lamp referring to “Malfunction
Indicator Lamp Check” in this section.
2) With the ignition switch OFF position, disconnect SUZUKI
scan tool if connected and using service wire (4), connect
diagnosis switch terminal (1) to ground terminal (2) in moni-
tor coupler (3).
3) With the ignition switch ON position and leaving engine OFF,
read DTC from flashing pattern of malfunction indicator
lamp. Refer to “Diagnostic Trouble Code Table”.
If lamp remains ON, go to “Diagnostic Flow Table A-4”.
4) After completing the check, turn the ignition switch OFF posi-
tion and disconnect service wire from monitor coupler.
DIAGNOSTIC TROUBLE CODE (DTC) CLEARANCE
Using Scan Tool
1) Connect SUZUKI scan tool (Tech-1) or generic scan tool
(Vehicle with immobilizer indicator lamp) to data link connec-
tor in the same manner as when making this connection for
DTC check.
2) Turn ignition switch ON.
3) Erase DTC and pending DTC according to instructions dis-
played on scan tool. Refer to scan tool operator’s manual for
further details.
4) After completing the clearance, turn ignition switch off and
disconnect scan tool from data link connector. NOTE:
If abnormality or malfunction lies in two or more areas,
malfunction indicator lamp indicates applicable codes
three times each.
And flashing of these codes is repeated as long as
diagnosis terminal is grounded and ignition switch is
held at ON position.
Take a note of diagnostic trouble code indicated first.

NOTE:
DTC and freeze frame data stored in ECM memory are
also cleared in following cases. Be careful not to clear
them before keeping their record.
When power to ECM is cut off (by disconnecting bat-
tery cable, removing fuse or disconnecting ECM con-
nectors)
When the same malfunction (DTC) is not detected
again during 40 engine warm-up cycles. (Vehicle with
immobilizer indicator lamp)

UNDERSIZE BEARING (0.25 mm) :
0.25 mm undersize bearing is available, in five kinds varying
in thickness.
To distinguish them, each bearing is painted in the following
colors at such position as indicated in figure.
Each color represents the following thickness at the center of
bearing.
Undersize of crankshaft main bearing thickness
If necessary, regrind crankshaft journal and select undersize
bearing to use with it as follows.
a) Regrind journal to the following finished diameter.
Finished diameter
: 44.732 – 44.750 mm (1.7611 – 1.7618 in.)
1) Using micrometer, measure reground journal diameter.
Measurement should be taken in two directions perpendicu-
lar to each other in order to check for out-of-round.
2) Using journal diameter measured above and alphabets
stamped on cylinder block, select an undersize bearing by
referring to table given below.
Check bearing clearance with newly selected undersize
bearing.
