ACTUATOR TESTS
Resistance Test (1991)
Disconnect actuator connector. Resistance between terminals
No. 1 and 2 should be 20 ohms. See Figs. 17-21. If resistance is not
correct, replace actuator assembly.
Operational Test (1991)
1) With connector disconnected, connect battery voltage to
terminal No. 1. See Figs. 17-21. Ground terminal No. 2. Connect
ammeter between positive side of battery and terminal No. 1 of
actuator connector.
2) Solenoid should make a click sound. Ammeter should read .
5-.7 amps. Connect positive side of battery to terminal No. 4 and
ground terminal No. 3. Actuator should pull in and stop.
3) While actuator is moving in, ammeter should read less than
.5 amps. When actuator travel reaches midpoint, disconnect terminal
No. 1 from positive side of battery. Actuator should return to
original position. If actuator does not test correctly, replace
actuator.
4) Reverse connections of terminals No. 4 and 3 in step 2).
Connect battery voltage to terminal No. 3 and ground terminal No. 4.
Actuator should move out then stop. While actuator is moving, ammeter
should read less than .5 amps.
1992
Remove actuator. Apply vacuum to actuator. Actuator linkage
holder should move more than 1.38" (35 mm). Actuator diaphragm should
hold vacuum. Replace actuator if actuator does not test correctly.
VEHICLE SPEED SENSOR TEST
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. Check continuity between vehicle speed sensor
terminals at instrument cluster. See Fig. 30 or 31.
2) Ensure continuity pulses on and off 4 times per revolution
of speedometer shaft connection. If continuity is not as specified,
replace vehicle speed sensor.

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 were recently published.
Further, revisions to all of these inspection communication standards
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
