HOW TO USE THIS MANUAL
MAINTENANCE, REPAIR AND
SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning procedures for the inspection, maintenance, repair
and servicing of the subject model. Unless other-
wise specified, each service procedure covers all
models. Procedures covering specific models are
identified by the model codes, or similar designati on
(engine type, transaxle type, etc.). A description
of these designations is covered in this manual
under “VEHICLE IDENTIFICATION”.
ON-VEHICLE SERVICE
“On-vehicle Service” are procedures for performing
inspections and adjustments of particularly impor-
tant locations with regard to the construction and
for maintenance and servicing, but other inspec-
tions (for looseness, play, cracking, damage, etc.
must also be performed.
SERVICE PROCEDURES
The service steps are arranged in numerical order
and attention must to be paid in performing vehicle
service are described in detail in SERVICE POINTS.
TERMS DEFINITION
STANDARD VALUE
Indicates the value used as the standard for judgin g
the quality of a part or assembly on inspection
or the value to which the part or assembly is cor-
rected and adjusted. It is given by tolerance.
LIMIT
Indicates a maximum or minimum value, the part
or assembly should be kept within, in order to be functional. This value is established outside the
standard value range.
REFERENCE VALUE
Indicates the adjustment value prior to starting th e
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be com-
pleted in a shorter time).
CAUTION
Indicates the presentation of information particula rly
vital to the worker during the performance of maint e-
nance and servicing procedures in order to avoid
the possibility of injury to the worker, or damage
to component parts, or a reduction of component
or vehicle function or performance, etc..
TIGHTENING TORQUE INDICATION
The tightening torque shown in this manual is a
basic value with a tolerance of
10% except the
following cases when the upper. and
of tightening torque are given. (1) The tolerance of the ‘basic value
10%.
(2) Special bolts or, the ‘like are
(3) Special tightening methods are used.
SPECIAL TOOL NOTE
When the MMC special tool is described, please
refer to the special tool
is located at the beginning of each group, for a
cross reference from the tool, number
to the special tool number that available in your
market..
MODEL INDICATIONS
The following abbreviations are used in this manual for classification of model types.
M/T
Indicates the manual transaxle, or models equipped with the manual transaxle.
A/T
Indicates the automatic transaxle, or models equip ped with the automatic transaxle.
MFI: Indicates the
fuel injection, or engines equipped with the fuel injection.
Turbo: Indicates the engine with turbocharger, or m odels equipped
such an
Non-turbo: Indicates the engine without turbocharger, or models equipped with, such anengine.
FWD: Indicates the front wheel drive vehicles.

Troubleshooting of electronic control systems for which the scan tool the basic outline
described below. Furthermore, even in systems for w hich the scan tool cannot be used, part of these
systems still follow this outline.
TROUBLESHOOTING CONTENTS
1. STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
The main procedures for diagnostic troubleshooting are shown.
2. SYSTEM OPERATION AND SYMPTOM VERIFICATION TESTS If verification of the trouble symptoms is difficul t, procedures for checking operation and verifying
trouble symptoms are shown.
3. DIAGNOSTIC FUNCTION The following diagnostic functions are shown.
l ,Method of reading diagnostic trouble codes
Method of erasing diagnostic trouble codes
lInput inspection service points
4. INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES
5. INSPECTION PROCEDURE FOR DIAGNOSTIC TROUBLE CODE S
Indicates the inspection procedures corresponding t o each diagnostic trouble code. (Refer to the
next page on how to use the inspection procedures.)
6. INSPECTION CHART FOR TROUBLE SYMPTOMS
If there are trouble symptoms, even though the scan tool displays no diagnostic inspection
procedures for each trouble symptom will be found b y means of this chart.
7. INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Indicates the inspection procedures corresponding t o each trouble symptoms the Inspection
Chart for Trouble Symptoms. (Refer to the next page on how to use the inspection procedures.)
8. DATA LIST REFERENCE TABLE
Inspection items and normal judgement values have b een provided in this chart as reference
9. CHECK AT ECU TERMINALS
Terminal numbers for the ECU connectors, inspection items and standard values have been provided
in this chart as reference information.
Terminal Voltage Checks
1. Connect a needle-nosed wire probe or paper clip to a voltmeter probe.
2.Insert the needle-nosed wire probe into each of the ECU connector from the wire side,
and measure the voltage while referring to the chec k chart.
NOTE
1. Measure voltage with the ECU connectors connecte d.
2. You may find it convenient to pull out the ECU t o make it easier to reach the connector
terminals.
3. Checks don’t have to be carried out in the order given in the chart.
Short-circuiting the positive probe between a connector damage
the vehicle wiring, the sensor, the ECU, or all thr ee.
Use care to prevent this
3. If voltage readings differ from Normal Condition values, related actuators, and
wiring, then replace or repair.

GENERAL How to Use Troubleshooting/Inspection Service Points
4.After repair or replacement, recheck the voltmeter to confirm the repair
the problem.
Terminal Resistance and Continuity Checks
1. Turn the ignition switch to off.
2. Disconnect the ECU connector.
3.Measure the resistance and check for continuity bet ween the terminals of the ECU
connector while referring to the check chart.
NOTE
Checks don’t have to be carried out in the order gi ven in the chart.
Cautlon
If resistance and continuity checks are performed the wrong terminals, damage
vehicle wiring, sensors, ECU, and/or ohmmeter may o ccur.
Use care to prevent this!
4.If the ohmmeter shows any deviation from the Normal Condition value, check the corresponding

HARNESS INSPECTION
Check for an open or short circuit in the harness b etween the terminals which were defective according
to the connector measurements. Carry out this inspe ction while referring to Volume 2 Electrical manual.
Here, “Check harness between power supply and termi nal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse”.
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even a fter replacing the ECU, repeat the inspection procedure
from the beginning.
