are continually republished. In addition to these, standards for Drive
Train and Transmissions have recently been promulgated. Participating
shops utilize these Uniform Inspection & Communication Standards as
part of the inspection process and for communicating their findings to
their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers mediation and arbitration through MAP/BBB-CARE and other non-
profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method
has been incorporated which includes the "mystery shopping" of
outlets.
We welcome you to join us as we continue our outreach... with
your support, both the automotive repair industry and your customers
will reap the benefits. Please visit MAP at our Internet site www.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF SERVICE REQUIREMENTS & SUGGESTIONS
It is MAP policy that all exhaust, brake, steering,
suspension, wheel alignment, drive-line, engine performance and
maintenance, and heating, ventilation and air conditioning, and
electrical services be offered and performed under the standards and
procedures specified in these sections.
Before any service is performed on a vehicle, an inspection
of the appropriate system must be performed. The results of this
inspection must be explained to the customer and documented on an
inspection form. The condition of the vehicle and its components will
indicate what services/part replacements may be "Required" or
"Suggested". In addition, suggestions may be made to satisfy the
requests expressed by the customer.
When a component is suggested or required to be repaired or
replaced, the decision to repair or replace must be made in the
customer's best interest, and at his or her choice given the options
available.
This section lists the various parts and conditions that
indicate a required or suggested service or part replacement.
Although this list is extensive, it is not fully inclusive. In
addition to this list, a technician may make a suggestion. However,
any suggestions must be based on substantial and informed experience,

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
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
are continually re-published. In addition to these, standards for
Drive Train and Transmissions have recently been promulgated.
Participating shops utilize these Uniform Inspection & Communication
Standards as part of the inspection process and for communicating
their findings to their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.

3) Tighten lock nut, and ensure brake pedal height is within
specification. Start engine to evacuate brake booster chamber. Stop
engine, and apply brake several times to remove vacuum from brake
booster.
4) Using hand pressure, depress brake pedal to measure free
play before resistance is felt. Free play distance for all models is
0.10-0.31" (3-8 mm). If distance is not within specification, it is
probably caused by excessive play between the brake pedal arm and the
clevis pin. Check and replace as necessary.
5) Start engine and apply 110 lbs. (490 N) of pressure to
brake pedal. With the carpet pulled back, measure the distance between
the brake pedal and the floorboard. If the distance is not 3.1-3.5"
(80-90 mm) check for air in brake hydraulic system, brake adjustment
or defective parking brake component or adjustment. Adjust or repair
as necessary.
LOAD-SENSING PROPORTIONING VALVE (LSPV)
Montero
1) Park vehicle on level surface. Remove excess weight from
vehicle. Make sure the lever is all the way towards the valve side.
Measure length of entire spring. See Fig. 1.
If spring length is not within specification, adjust spring
support until correct length is obtained. See LSPV SPRING LENGTH
table.

BRAKE BOOSTER PUSH ROD
Page 220 of 1501
Adjustment (Except Diamante)
1) Place the Push Rod Adjusting Gauge (MB991714) in the
master cylinder, position gauge shaft so it contacts master cylinder
piston and tighten wing bolt.
2) Apply a vacuum of 9.7 psi (-66.7 kPa) for Eclipse, Galant\
,
Montero and 3000GT and 19.6 psi (-66.7 kPa) for Mirage and Montero
Sport to the brake booster using a hand held vacuum pump.
3) Rotate the gauge tool so it is positioned offset from
center of the brake booster. See Fig. 2.

4) Move the gauge tool towards the center so the shaft
contacts the end of the brake booster push rod. If contact is not as
shown in position "A", shorten the rod if position "B" is present, or
lengthening it if position "C" is present. See Fig. 3.

and check fluid input and output pressures at LSPV. See
LSPV PRESSURE SPECIFICATIONS table.
4) Disconnect spring at support and pull spring and lever
toward support until spring length is 10.1" (257 mm). See Fig. 1.
Slowly depress brake pedal and check input and output pressures at
LSPV. See LSPV PRESSURE SPECIFICATIONS table. If fluid input pressure
is okay and output pressure is not within specification, replace LSPV
assembly. Remove gauges and bleed brake system.

contact, deterioration, seizure or oil saturation. Measure distance
from clutch disc surface to head of rivet. Replace clutch disc if
distance is less than .012" (.30 mm). Replace worn or defective
components as necessary. See Fig. 4.
CAUTION: Install clutch disc with manufacturer's stamp mark (located
near hub of clutch disc) toward pressure plate.
Installation

clutch disc. If reusing pressure plate, ensure index marks are
aligned. Tighten bolts evenly in a crisscross pattern to
specification. See TORQUE SPECIFICATIONS . See Fig. 3.
2) Clean release bearing sliding surface. DO NOT clean
