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 engine and transmission-related component
parts, this manual covers only on-vehicle
inspections, adjustments, and 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 the presentation of information particularly
vital to the 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
Tightening torques (units: N×m) are set to take into
account the central value and the allowable
tolerance. The central value is the target value,
and the allowable tolerance provides the checking
range for tightening torques. If bolts and nuts are
not provided with tightening torques, refer to
P.00-39.

GENERAL -How to Use Troubleshooting/Inspection Service Points00-10
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 andcircuit
inspection are listed on a separate page, and
are given here for reference.
5. Inspect the contact condition at each connectorterminal.
(Refer to Connector Inspection Service Points.)
The connector position can be located in the wiring diagram in the
electrical wiring manual bymeans ofthis symbol.
Caution
After carrying out connector inspection, always be sure to
reconnect the connector as it was before.
6. Confirm that there are trouble symptoms. If trouble symptomshave
disappeared, the connector may have been inserted incorrectly and the
trouble symptom mayhave disappeared during inspection.
If it seemsthat trouble symptoms still remain, proceed to the nextpage of
instructions.
7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open orshort circuit in the harness between the connectors, socheck the harness.
Alternatively, the cause may be a defectiveECU, so try replacing the ECU andcheck
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.

GENERAL -Precautions Before Service00-32
Other precautions:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious gloves
where practicable.
DAvoid contaminating clothes, particularly underpants, with
oil.
DDo not put oily rags in pockets, the use of overalls without
pockets will avoid this.
DDo not wear heavily soiled clothing and oil-impregnated
foot-wear. Overalls must be cleaned regularly and kept
separately from personal clothing.
DWhere there is a risk of eye contact, eye protection should
be worn, for example, chemical goggles or face shields;
in addition an eye wash facility should be provided.
DObtain First Aid treatment immediately for open cuts and
wounds.
DWash regularly with soap and water to ensure all oil is
removed, especially before meals (skin cleansers and
nail brushes will help). After cleaning, the application of
preparations containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
DUse barrier creams, applying them before each work
period, to help the removal of oil from the skin after work.
DIf skin disorders develop, obtain medical advice without
delay.

PRECAUTIONS BEFORE SERVICE
LEARNING FUNCTION OF GDI ENGINE
1. Purpose
On the GDI engine equipped cars, when replacement of the ECU (for engine control) or resetting
of the battery* has been performed, an idle learning function of the ECU (for engine control) will
be required.
The idle learning function will be completed by running the engine at idle by the following procedure.
NOTE:
*: Disconnection of ECU (for engine control) battery backup power supply (disconnection of battery
terminals or ECU connectors)
2. Idle Learning Procedure
(1) Start the engine, and warm up the engine until its coolant temperature reaches 85°C or higher.
When the engine coolant temperature is 85°C or higher, you have only to turn the ignition
switch to the ON position.
(2) Turn the ignition switch to the LOCK (OFF) position, and stop the engine.
(3) After lapse of ten or more seconds, restart the engine.
(4) Run the engine at idle for ten minutes under the following conditions.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner and heater: Not operational
DEngine coolant temperature: 83°C or higher
(5) Stop the engine.
(6) Restart the engine, and run it at idle for ten minutes under the following condition.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner: Operational (Temperature set at “maximum cool”, fan at high speed, and
windows fully opened)
DEngine coolant temperature: 83°C or higher
(7) Repeat steps (5) and (6).
NOTE:
1) When the atmospheric temperature is 20°C or more and the air conditioner has continuously
been operated, step (7) may be omitted.
2) During idling operation of the engine in steps (4) and (6), when engine operation switches
from lean operation to stoichiometric operation, engine stall can occur. In this case, clean the
throttle body (throttle valve) thoroughly, and then repeat step (1) and the subsequent steps.
