MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards

A/C SWITCH
When turned on, the A/C system will operate if blower motor
control lever is in a position other than OFF. When activated, A/C
switch allows A/C compressor clutch to engage and operate the
compressor.
A/C ENGINE COOLANT TEMPERATURE SWITCH
The A/C engine coolant temperature switch, located on
thermostat housing, is wired in series with compressor clutch. When
coolant temperature is greater than switch control temperature, power
to compressor is cut and compressor is turned off until temperature
returns to operating range. Switch will turn on at 226
F (108C) and
off at 235-243F (112-118C).
AIR SELECTOR LEVER
The lever moves horizontally to select source of air used
inside passenger compartment. Lever moves from position on left
(outside air mode) to position on right (recirculated air mode). Lev\
er
should be set in recirculated air mode for maximum A/C cooling.
BLOWER MOTOR CONTROL SWITCH
Blower motor control switch rotates to select blower motor
speeds. As switch is rotated from left or OFF position, increasing
speeds of blower operation are selected. In order for A/C system to
operate, blower motor control switch must be in a position other than
OFF.
MODE SELECTOR KNOB
Mode selector knob has six modes available to achieve desired
distribution of air from various outlets. When knob is rotated fully
to left (counterclockwise), airflow is directed to upper passenger
area. In second position (clockwise), airflow is directed to upper
passenger area and slightly to leg area. Position 3, directs air
mostly to leg area and slightly to upper passenger area. Position 4,
directs air exclusively to leg area. Position 5, directs air to leg
area and to windshield and door windows. Position 6, directs air
exclusively to windshield and door windows.
TEMPERATURE CONTROL KNOB
Temperature control knob operates blend-air door in
heater/air conditioning unit, mixing cooled and heated air so that
selected air temperature can be obtained. The system will provide
cooled air when A/C switch is in ON position and blower motor is in
any position other than OFF. Temperature control knob should be on far
left (maximum cooling) side of temperature selection scale when
maximum A/C cooling is desired.
DUAL-PRESSURE SWITCH
The dual-pressure switch, mounted on receiver-drier, is wired
in series with compressor clutch. Whenever system pressures drop below
or increase above control points of switch, power supplied to
compressor will be cut and compressor function will cease until
pressures are back to normal operating ranges.

1998 AIR BAG RESTRAINT SYSTEMS
Mitsubishi

DESCRIPTION & OPERATION
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all WARNINGS and SERVICE PRECAUTIONS.
Supplemental Restraint System (SRS) consists of an SRS
warning light, driver-side and passenger-side air bag module,
clockspring, right and left front impact sensors, and SRS Air Bag
Control Unit (ECU). The SRS-ECU contains an analog and a safing impact\
sensor. See Fig. 1.
Air bags are designed to deploy in a frontal or near frontal
impact of moderate to severe force. For air bags to deploy, ignition
must be on and safing impact sensor and at least one front impact
sensor must activate simultaneously.
Fig. 1: Locating SRS Components
Courtesy of Mitsubishi Motor Sales of America.
SRS WARNING LIGHT
Page 108 of 1501
When ignition switch is turned to ON or START position, SRS
warning light on instrument panel should come on for about 7 seconds
and then go off. This indicates SRS-ECU has determined SRS is
functioning properly. If SRS warning light flashes, stays on all the
time, or does not come on, a fault exists in SRS. See
DIAGNOSIS & TESTING.
FRONT IMPACT SENSORS
Sensors are inertia switches that verify direction and
severity of impact. If impact is great enough, switch contacts close,
completing an electrical circuit. Front impact sensors are located
under front fenders. See Fig. 1.
AIR BAG MODULE(S)
An inflator assembly in the air bag module produces nitrogen
gas to fill air bag. See Fig. 1. When a small amount of current from
SRS-ECU is applied, ignitor starts a thermal reaction, which spreads
to a pellet-filled canister that produces nitrogen gas. Gas pressure
builds and discharges from inflator through a diffuser and screen
assembly, forcing trim cover to burst along its seams until air bag is
fully inflated. When air bag is fully inflated, gas escapes through
vents on sides of air bag.
SRS AIR BAG CONTROL UNIT (ECU)
SRS-ECU (with integral safing and analog impact sensor) is
located behind front floor console assembly. See Fig. 1. If a system
fault occurs, SRS-ECU memory stores a diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC is located under left side of dash. See Fig. 1. DLC is
used to access SRS self-diagnostics through Mitsubishi Multi-Use
Tester II (MUT-II) (MB991502).
CLOCKSPRING
Clockspring connects driver-side air bag module to steering
column wiring, forming SRS circuit. See Fig. 1. Clockspring is a flat,
ribbon-like cable that winds and unwinds when steering wheel is
turned. Because of clockspring's constant movement, it is the most
fragile part in the system.
SYSTEM OPERATION CHECK
WARNING: After servicing, always turn ignition on from passenger-side
of vehicle in case of accidental air bag deployment.
Turn ignition switch to ON position. SRS warning light on
instrument panel should come on for about 7 seconds and then turn off.
This indicates SRS is functioning properly. If SRS warning light does
not come on, stays on, or comes on while driving, SRS is
malfunctioning and needs repair. See DIAGNOSIS & TESTING.
SERVICE PRECAUTIONS
Observe the following precautions when working with SRS:
* Disable SRS before servicing any SRS or steering column
Page 109 of 1501
component. Failure to do this may result in accidental air
bag deployment and possible personal injury. Refer to
DISABLING & ACTIVATING AIR BAG SYSTEM .
* For about 60 seconds after air bag system is disabled, it
retains enough voltage to deploy air bags. After disabling
system, wait at least 60 seconds before servicing.
* After servicing, always turn ignition on from passenger-side
of vehicle in case of accidental air bag deployment.
* After servicing, check SRS warning light to verify system
operation. See SYSTEM OPERATION CHECK.
* Always wear safety glasses when servicing or handling an
air bag.
* The SRS-ECU must be stored in its original special container
until used for service. It must be stored in a clean, dry
place, away from sources of extreme heat, sparks and high
electrical energy.
* DO NOT expose air bag module and clockspring to temperatures
greater than 200
F (93 C).
* When placing a live air bag module on a bench or other
surface, always face air bag module and trim cover up, away
from surface. This will reduce motion of module if air bag
accidentally deploys.
* After air bag deploys, air bag surface may contain deposits
of sodium hydroxide, which irritates skin. Always wear
safety glasses, rubber gloves and long-sleeved shirt during
clean-up. Wash hands using mild soap and water. Follow
correct clean-up and disposal procedures. Refer to
DISPOSAL PROCEDURES .
* Because of critical system operating requirements, DO NOT
service any SRS components. Repairs are only made by
replacing defective part(s).
* DO NOT allow any electrical source near inflator on the back
of air bag module.
* When carrying a live (undeployed) air bag module, trim cover
must be pointed away from body to minimize injury in case of
accidental air bag deployment.
* DO NOT probe wire harness connector terminals. Instead, use
SRS Check Harness (MB991530).
* DO NOT probe a wire through insulator, as this will damage
it and eventually cause failure due to corrosion.
* When performing electrical tests, prevent accidental
shorting of terminals. Such shorts can damage fuses or
components and may cause a second fault code to set, making
diagnosis of original problem more difficult.
* Never use an analog volt/ohm meter or test light in place of
a Digital Volt/Ohm Meter (DVOM). Use only a DVOM with a
maximum test current of 2 mA (milliamps) at minimum range of
resistance measurement. Also see SPECIAL TOOLS.
* If SRS is not fully functional for any reason, DO NOT drive
vehicle until system is repaired and is fully functional. DO
NOT remove bulbs, modules, sensors or other components, or
in any way disable system from operating normally. If SRS is
not functional, park vehicle until repairs are made.
SPECIAL TOOLS
To avoid air bag deployment when working on SRS, DO NOT use
electrical test equipment such as test lights, battery or A/C-powered
volt/ohmmeter, or any type of electrical equipment other than those
specified by manufacturer. See SRS RECOMMENDED TOOLS table.

DISABLING & ACTIVATING AIR BAG SYSTEM
WARNING: SRS system voltage is maintained for about 60 seconds after
battery cable is disconnected. After disconnecting battery
cable, wait at least 60 seconds before servicing SRS.
Failure to wait may cause accidental air bag deployment and
possible personal injury.
To disable system, turn ignition switch to LOCK position.
Disconnect negative battery cable. Shield cable end. Wait at least 60
seconds before servicing. To activate system, reconnect negative
battery cable.
DISPOSAL PROCEDURES
WARNING: Undeployed air bag must be deployed before disposal.
Disposing of an undeployed air bag may violate federal,
state and/or local laws. This also applies to vehicles that
are to be scrapped. Never sell a used air bag module.
UNDEPLOYED AIR BAG
WARNING: Deploy air bag outdoors and away from people. Air bag
deployment makes a loud noise. NEVER deploy air bag module
with trim cover face down.
NOTE: If replacing a deployed air bag, both front impact sensors
and SRS-ECU must also be replaced. If vehicle is to be
scrapped, perform PROCEDURE 1 (ON-VEHICLE DEPLOYMENT) below.
If vehicle will continue to be operated, perform PROCEDURE 2
(OFF-VEHICLE DEPLOYMENT) below.
Procedure 1 (On-Vehicle Deployment)
1) Before proceeding, follow air bag service precautions. See
SERVICE PRECAUTIONS . Open all doors and windows. Move vehicle to an
isolated area. Disconnect negative battery cable and wrap tape around
cable terminal.
2) Disconnect positive battery cable. Remove battery. Wait at
