Check transaxle oil for leakage, contamination and level
referring to “Manual Transaxle Oil Level Check in
Section 5B”.
Manual Transaxle Oil ReplacementS6RW0D0206028
Change transaxle oil with new specified oil referring to
“Manual Transaxle Oil Change in Section 5B”.

All Latches, Hinges and Locks InspectionS6RW0D0206033
Doors
Check that each door of front, rear and back doors
opens and closes smoothly and locks securely when
closed.
If any malfunction is found, lubricate hinge and latch or
repair door lock system.
Engine Hood
Check that secondary latch operates properly (check
that secondary latch keeps hood from opening all the
way even when pulling hood release handle inside
vehicle.) Also check that hood opens and closes
smoothly and properly and hood locks securely when
closed.
If any malfunction is found, lubricate hinge and latch, or
repair hood lock system.I5RW0A020006-01

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.)
