HOW TO USE THIS MANUAL

SCOPE OF MAINTENANCE, REPAIR
AND SERVICING EXPLANATIONS

This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Note, however,
that for engineand transmission-related component
parts, this manual covers only on-vehicle
inspections, adjustments, an d the removal and
installation procedures for major components.
For detailed information concerning the inspection,
checking, adjustment, disassembly and reassembly
of the engine, transmission and major components
after they have been removed from the vehicle,
please refer to separate manuals covering the
engine and the transmission.

ON-VEHICLE SERVICE

“On-vehicle Service” is procedures for performing
inspections and adjustments of particularly
important locations with regard to the construction
and for maintenance and servicing, but other
inspection (for looseness, play, cracking, damage,
etc.) must also be performed.

INSPECTION

Under this title are presented inspection and
checking procedures to be performed by using
special tools and measuring instruments and by
feeling, but, for actual maintenance and servicing
procedures, visual inspections should always be
performed as well.

DEFINITION OF TERMS

STANDARD VALUE

Indicates the value used as the standard for judging
the quality of a part or assembly on inspection
or the value to which the part or assembly is
corrected and adjusted. It is given by tolerance.

LIMIT

Shows the standard for judging the quality of a
part or assembly on inspection and means the
maximum or minimum value within which the part
or assembly must be kept functionally or in strength.
It is a value established outside the range of
standard value.

REFERENCE VALUE

Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be
completed in a shorter time).

CAUTION

Indicates t h e presentation of information particularly
vital to t he worker during the performance of
maintenance 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.

INDICATION OF TIGHTENING TORQUE

The tightening torque shown in this manual is a
basic value with a tolerance of ±10% except the
following cases when the upper and lower limits
of tightening torque are given.
(1) The tolerance of the basic value is within ±10%.
(2) Special bolts or the like are in use.
(3) Special tightening methods are used.

HOW TO USE THE INSPECTION PROCEDURES

The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors,
components, the ECU and the harnesses between connectors, in that order. These inspection procedures
follow this order, and they first try to discover a problem with a connector or a defective component.

3. Detailed inspection procedures (methods)
such as component inspection and circuit
inspection are listed on a separate page, and
are given here for reference.

6. Confirm that there are trouble symptoms. If trouble symptoms have
disappeared, the connector may have been inserted incorrectly and the
trouble symptom may have disappeared during inspection.
If it seems that trouble symptoms still remain, proceed to the next page of
instructions.

7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open or short circuit in the harness between the connectors, so check the harness.
Alternatively, the cause may be a defective ECU, so try replacing the ECU and check
if the trouble symptom disappears.

HARNESS INSPECTION

Check for an open or short circuit in the harness between the terminals which were defective according
to the connector measurements. Carry out this inspection while referring to the electrical wiring manual.
Here, “Check harness between power supply and terminal 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 after replacing the ECU, repeat the inspection procedure
from the beginning.

How to Use Troubleshooting/Inspection Service Points

CONNECTOR MEASUREMENT SERVICE POINTS

Turn the ignition switch to OFF when connecting disconnecting
the connectors, and turn the ignition switch to ON when
measuring if there are no instructions to be contrary.

Extra-thin probe

Test bar

Connector

Inspection harness
for connector pin
contact pressure

Harness connector

IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)

Waterproof Connectors

Be sure to use the special tool (harness connector). Never
insert a test bar from the harness side, because to do so
will reduce the waterproof performance and result in corrosion.

Ordinary (non-waterproof) Connectors

Check by inserting the test bar from the harness side. Note
that if the connector (control unit, etc.) is too small to permit
insertion of t h e test bar, it should not be forced; use a special
tool (the extra-thin probe in the harness set for checking
for this purpose.

IF INSPECTING WITH THE CONNECTOR DISCONNECTED
<When Inspecting a Female Pin>

Use the special tool (inspection harness for connector pin
contact pressure in the harness set for inspection).
The inspection harness for connector pin contact pressure
should be used. the test bar should never be forcibly inserted,
as it may cause a defective contact.

<When Inspecting a Male Pin>

Touch the pin directly with the test bar.

Caution
At this time, be careful not to short the connector pins
with the test bars. To do so may damage the circuits
inside the ECU.
