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
ªOn-vehicle Serviceº 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
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.

GENERAL ± Precautions Before Service00-28
Other precautions:
Avoid prolonged and repeated contact with oils,
particularly used engine oils.
Wear protective clothing, including impervious gloves
where practicable.
Avoid contaminating clothes, particularly underpants, with
oil.
Do not put oily rags in pockets, the use of overalls without
pockets will avoid this.
Do not wear heavily soiled clothing and oil-impregnated
foot-wear. Overalls must be cleaned regularly and kept
separately from personal clothing.
Where 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.
Obtain First Aid treatment immediately for open cuts and
wounds.
Wash 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.
Do not use petrol, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
Use barrier creams, applying them before each work
period, to help the removal of oil from the skin after work.
If skin disorders develop, obtain medical advice without
delay.

The idle speed is controlled automatically by the idle speed
control (ISC) system.
7. If the idle speed is outside the standard value, inspect
the MPI components by referring to GROUP 13A ±
Troubleshooting.
IDLE MIXTURE CHECK11100210265
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Check that the basic ignition timing is within the standard

Standard value: 5 BTDC+2
3. Turn the ignition switch to OFF and connect the MUT-II
to the diagnosis connector.
4. Start the engine and run it at 2,500 r/min for 2 minutes.
5. Set the CO, HC tester.
6. Check the CO contents and the HC contents at idle.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
7. If there is a deviation from the standard value, check
the following items:
Diagnosis output
Closed-loop control (When the closed-loop control
is normal, the output signal of the oxygen sensor
changes between 0 ± 400 mV and 600 ± 1,000 mV
at idle.)
