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.

DATA LINK CONNECTOR (DLC)
ELC (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) 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.
PRECAUTION IN DIAGNOSING TROUBLE
Do not 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 checked by using SUZUKI scan
tool (Tech-1) or generic scan tool (Vehicle with immobilizer indicator lamp). 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.
Priorities for diagnosing troubles (Vehicle with immobilizer indicator lamp).
If two or more DTCs are stored, proceed to the flow table of the DTC which has detected earliest in the order
(it can be identified by referring to freeze frame data) and follow the instruction in that table.
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
–Diagnostic trouble codes (DTCs) other than DTC P0171/P0172 (Fuel system too lean/too rich), DTC
P0300/P0301/P0302/P0303/P0304 (Misfire detected) and DTC P0400 (EGR flow malfunction)
–DTC P0171/P0172 (Fuel system too lean/too rich) and DTC P0400 (EGR flow malfunction)
–DTC P0300/P0301/P0302/P0303/P0304 (Misfire detected)
Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before inspection and observe what
is written there.
ECM Replacement
When substituting a known-good ECM, check for following conditions. Neglecting this check may cause
damage to a known-good ECM.
–Resistance value of all relays, actuators is as specified respectively.
–MAP sensor and TP sensor are in good condition and none of power circuits of these sensors is shorted
to ground.AMBIENT
TEMPERATURETIME TO CUT POWER TO ECM

ENGINE GENERAL INFORMATION AND DIAGNOSIS 6-13
1. CUSTOMER COMPLAINT ANALYSIS
Record details of the problem (failure, complaint) and how it occurred as described by the customer. For this
purpose, use of such an inspection form will facilitate collecting information to the point required for proper anal-
ysis and diagnosis.
2. DTC/FREEZE FRAME DATA CHECK, RECORD AND CLEARANCE
First, check DTC (including pending DTC), referring to “DTC check” section. If DTC is indicated, print it and
freeze frame data or write them down and then clear them by referring to “DTC clearance” section. DTC indi-
cates malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the
past and the normal condition has been restored now. To check which case applies, check the symptom in
question according to Step 4 and recheck DTC according to Step 5.
Attempt to diagnose a trouble based on DTC in this step only or failure to clear the DTC in this step will lead to
incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
3. and 4. VISUAL INSPECTION
As a preliminary step, be sure to perform visual check of the items that support proper function of the engine
referring to “Visual Inspection” section.
5. TROUBLE SYMPTOM CONFIRMATION
Based on information obtained in Step 1 Customer complaint analysis and Step 2 DTC/freeze frame data check,
confirm trouble symptoms. Also, reconfirm DTC according to “DTC Confirmation Procedure” described in each
DTC Diagnosis section.
6. and 7. RECHECKING AND RECORD OF DTC/FREEZE FRAME DATA
Refer to “DTC check” section for checking procedure.
8. ENGINE BASIC INSPECTION AND ENGINE DIAGNOSIS TABLE
Perform basic engine check according to the “Engine Basic Inspection Flow Table” first. When the end of the
flow table has been reached, check the parts of the system suspected as a possible cause referring to ENGINE
DIAGNOSIS TABLE and based on symptoms appearing on the vehicle (symptoms obtained through steps of
customer complaint analysis, trouble symptom confirmation and/or basic engine check) and repair or replace
faulty parts, if any.
9. TROUBLESHOOTING FOR DTC (See each DTC Diag. Flow Table)
Based on the DTC indicated in Step 5 and referring to the applicable DTC diag. flow table in this section, locate
the cause of the trouble, namely in a sensor, switch, wire harness, connector, actuator, ECM or other part and
repair or replace faulty parts.
10. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to
“INTERMITTENT AND POOR CONNECTION” in Section 0A and related circuit of DTC recorded in Step 2.
11. FINAL CONFIRMATION TEST
Confirm that the problem symptom has gone and the engine is free from any abnormal conditions. If what has
been repaired is related to the DTC, clear the DTC once, perform DTC confirmation procedure and confirm that
no DTC is indicated.NOTE:
If only Automatic transmission DTCs (P0702-P1709) or Immobilizer DTCs (P1620-P1623) are indicated
in this step, perform trouble diagnosis according to “Diagnosis” in Section 7B or Section 8G.
