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 -Standard Part/Tightening-Torque Table00-39
STANDARD PART/TIGHTENING-TORQUE TABLE
Each torque value in the table is a standard value
for tightening under the following conditions.
(1) Bolts, nuts and washers are all made of steel
and plated with zinc.
(2) The threads and bearing surface of bolts and
nuts are all in dry condition.The values in the table are not applicable:
(1) If toothed washers are inserted.
(2) If plastic parts are fastened.
(3) If bolts are tightened to plastic or die-cast
inserted nuts.
(4) If self-tapping screws or self-locking nuts are
used.

NOTE
1. Be sure to use only the specified bolts and nuts, and always tighten them to the specified torques.
2. Bolts marked with indications such as 4T or 7T are reinforced bolts. The larger the number, the
greater the bolt strength.

OUTLINE OF CHANGES
Some service procedures have been revised as the following changes have been made to comply to
the Emission Regulation StepIII.
DInjection timing and idle speed check and adjustment have bee changed as the electronic-controlled
fuel injection pump has been introduced.
DThe oil pan has a cover in order to reduce noise due to an enhanced engine output.
DA crank angle sensor and crankshaft sensing blade have been added due to the introduction of
an electronic-controlled fuel injection pump. Due to this change, the timing belt front lower cover
has been reshaped.
DThe tightening torque of the cylinder head bolts and the cylinder head gasket have been changed.

OPERATION TEST OF MITSUBISHI SC
1. Connect the MUT-
IIto the 16-pin diagnosis connector.
Caution
Turn the ignition switch to the LOCK (OFF) position
when connecting and disconnecting the MUT-
II.
2. Move the shift lever to the neutral , or the selector
lever to the P range.
3. Start the engine.
4. Use the MUT-
IIto activate the Actuator Test (item No.05)
while depressing the accelerator pedal fully. Check that
the engine speed should decrease gradually.
Caution
Activate the Actuator Test for three seconds.
Release the accelerator pedal immediately after the
Actuator Test is complete, or the engine speed will
rise.
NOTE
During the Actuator Test, the SC-ECU transmits the signal,
which requests no torque and wide open throttle, to the
engine-ECU or engine-A/T-ECU for three seconds.
WHEEL SPEED SENSOR (FR) CHECK
Refer to Basic Manual GROUP 35B - On-vehicle service.
VEHICLE SPEED SENSOR CHECK
Refer to Basic Manual GROUP 54A - Combination Meter.

WARNING REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring, and interconnecting
wiring. Other SRS-related components (that mayhave to be removed/installed in connectionwith SRS service or maintenance) are
indicated in the table of contents by an asterisk(*).
