WARNING REGARDING SERVICING OF SUPPLEMENTAL
RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLE
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 the driver and passenger (from rendering the SRS inoperative).
(2) The SRS components should not be subjected to temperature of 93_C or more. So, remove
the SRS-ECU, driver’s and front passenger’s air bag modules and clock spring before drying
or baking the vehicle after painting.
(3) Service or maintenance of any SRS component or SRS-related component must be performed
only at an authorized MITSUBISHI dealer.
(4) 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 SRS component or any SRS-related component.
NOTE
Section titles with asterisks (*) in the table of contents in each group indicate operations requiring warnings.

HOW TO READ CIRCUIT DIAGRAMS
The circuit of each system from fuse (or fusible link) to earth is shown. The power supply is shown
at the top and the earth at the bottom to facilitate understanding of the current flow.
Indicates the power supply in the control
unit. If no voltage is displayed, this
indicates SYSTEM voltage.
Indicates power take out.
Indicates connector No. The same
No. as in the wiring harness diagram
is used.
Connector numbers enclosed by
frame are indicated with the
connector symbols at the lower part
of the page.
Connector numbers not enclosed by
a frame indicate components which
are integrated with the harness.
Indicates harness junction point No. for
another system. It corresponds to the
junction point No. indicated on the
destination system circuit diagram.
Indicates the circuit name to be
connected. The arrow indicates the
current flow direction.
An “X” at the end of a connector No.
indicates that the connector is connected
to a centralized junction that is shown
in the section “CENTRALIZED JUNC-
TION”.
Indicates the operating condi-
tions of the engine coolant
temperature switch, etc.
Indicates the connector symbol.
Connectors in the circuit diagram are
indicated in numerical order.
Indicates shield wire.
Indicates that terminal is connected via
a plate in the relay box.
Each circuit diagram consists of
block(s). The blocks are divided by
page number.
Indicates that the diagram continues
at
Awhich belongs to the block
in the same circuit.2
Indicate that the current flows
from down to up. Bi-directional
arrows indicate that the
direction of current flow
changes when communication
is in progress.

OPERATION

DWhen the ignition switch is turned “ON”, the
blower relay is energized. If the blower switch
is turned “ON” (LO, ML, MH, or HI position)
in this condition, the blower is activated through
the circuit via resistor at a speed corresponding
to the blower switch position.TROUBLESHOOTING HINTS

1. Blower motor is energized at one switch position
and not energized at another.
DCheck resistor.
DCheck blower switch.
2. Blower motor is energized only when switch
is positioned in HI.
DCheck resistor.

IN ORDER TO PREVENT VEHICLES FROM FIRE
“Improper installation of electrical or fuel related parts could cause a fire. In order to retain the high
quality and safety of the vehicle, it is important that any accessories that may be fitted or modifications/repairs
that may be carried out which involve the electrical or fuel systems, MUST be carried out in accordance
with MMC’s information/Instructions”.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer. Adequate means of skin protection and washing facilities
must be provided.
Recommended Precautions
The most effective precaution is to adapt working practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by using enclosed systems for handling used engine
oil and by degreasing components, where practicable, before handling them.
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.

(4) Hold the special tool (MB991668) to the middle of
the belt between the pulleys (at the place indicated
by the arrow) about 10 - 20 mm away from the rear
surface and so that it is perpendicular to the belt
(within an angle of±15°).
(5) Gently tap the middle of the belt between the pulleys
(at the place indicated by the arrow) with your finger
as shown in the illustration, and check that the
vibration frequency of the belt is within the standard
value.
Standard value: 110 - 144 Hz
Caution
1) Check the vibration frequency of the belt when
the temperature of the surface of the belt is
as close as possible to normal temperature.
2) Do not let any contaminants such as water
or oil get onto the microphone.
3) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
4) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.
5) Do not take the measurement while the
vehicle’s engine is running.

Use the belt tension gauge and check that the belt tension
of the middle of the belt between pulleys
(at the place indicated by arrow) is within the standard
value.
Standard value: 245 - 412 N
2. If the value is outside the standard value, replace the
drive belt.Power steering
