All Makes and Models
INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
The Motorist Assurance Program was formed in 1992 by forty
(40) companies who were concerned about the image of automotive
service establishments. Today, MAP is an industry-wide association
dedicated to strengthening consumer satisfaction with the automotive
repair industry. MAP's participants represent the majority of the
nation's multi-bay retail automotive outlets, their parts and
equipment suppliers, independent repair shops, industry associations,
car companies, manufacturers representatives, and the trade press. MAP
is developing standards of service, uniform inspection procedures
and other programs to assure consumers of the industry's
professionalism and the commitment to excellence shared by MAP's
sponsoring companies.
MAP's achievements to date include production and
distribution (over 280,000) of the consumer brochure "How to Find Your
Way Under the Hood and Around Your Car", development of a Pledge of
Satisfaction to Consumers and Standards of Service and establishment
of relationships with regulatory agencies.
As auto repair becomes an issue for federal and state
regulators, MAP is working to educate government leaders on the
dynamics of automotive service and the self-monitoring efforts MAP has
undertaken on the industry's behalf. MAP's sponsoring companies are
becoming well-known to government representatives as exemplary
businesses working to improve the industry. Media sources also look to
MAP to provide information and advice to consumers and on working with
automotive technicians and repair establishments.
In the next few months, MAP plans to assist member repair
facilities in implementing the MAP Pledge to Customers, establishing
an alternate dispute resolution system to help resolve customer
complaints within the industry, and developing a shop accreditation
program to encourage policies in concert with the MAP Standards of
Service and Inspection Guidelines.
MAP has united the aftermarket behind its consumer-oriented
goals and has established itself both within and outside of the
industry. We welcome you to join us as MAP continues its outreach.
With your support, both the automotive repair industry and your
customers will reap the benefits. Please contact MAP at:
It is MAP policy that all exhaust, brake, ABS, steering and
suspension, wheel alignment, tires and wheels, driveline, engine
performance and maintenance and heating, ventilation and air
conditioning services be offered and performed under the guidelines
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 needs expressed by
the customer.
This section lists the various parts and conditions that
indicate required or suggested service or part replacement. Although
this list is extensive, it is not inclusive. In addition to this list,
a technician may make a suggestion. This suggestion must be based on
substantial and informed experience or the vehicle manufacturer's
recommended service interval.
Some conditions indicate that service or part replacement is
required because the part in question is no longer providing the
function for which it is intended, does not meet a vehicle
manufacturer's design specification or is missing.
* Example: An exhaust pipe has corroded severely and has a hole
in it through which exhaust gases are leaking. Replacement of
the exhaust pipe in this case is required due to functional
failure.
* Example: A brake rotor has been worn to the point where it
measures less than the vehicle manufacturer's specifications.
Replacement of the rotor is required because it does not meet
design specifications.
Some conditions indicate that a service or part replacement
is suggested because the part is close to the end of its useful life
or to address a customer's need, convenience or request. If a
customer's vehicle has one of these conditions, the procedure may only
be to suggest service.
* Example: An exhaust pipe is rusted, corroded or weak, but no
leaks are present. In this case, the exhaust pipe has not
failed. However, there is evidence that the pipe may need
replacement in the near future. Replacement of the pipe may
be suggested for the customer's convenience in avoiding a
future problem.
* Example: The customer desires improved ride and/or handling,
but the vehicle's shocks or struts have not failed. In this
case, replacement may be suggested to satisfy the customer's
wishes. In this case, replacement of the shocks or struts may

BRAKE SERVICE PROCEDURES REQUIRED AND SUGGESTED
FOR PROPER VEHICLE OPERATION
ANTI-LOCK BRAKE SYSTEMS: GENERAL
Anti-lock brake systems are considered an essential part of
brake systems on which they are found .
Anti-lock brake systems are commonly referred to as "ABS"
and will be referred to as "ABS" throughout these guidelines. Some
ABS components also function as part of a traction control system
(TCS). Inspection, diagnostic and service procedures vary. Refer
to appropriate service manuals for vehicle's specific requirements.
WARNING: When diagnosing and servicing high pressure components,
observe safety procedures and equipment requirements
established by the vehicle manufacturer to reduce the
possibility of serious personal injury.
CAUTION: Most manufacturers prohibit the use of DOT 5 brake fluid
in a system equipped with ABS.
NOTE: Intermittent electrical conditions are often caused by a
loss of ground, poor connection, or water intrusion into

GENERAL INFORMATION
Brake Systems - Motorist Assurance Program
Standards For Automotive Repair
All Makes & Models
INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program (MAP) 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.
The Motorist Assurance Program was established as an
industry-wide effort to address concerns raised by regulators, the
media and consumers questioning our ethics and methods of doing
business. The automotive repair industry had been bombarded by months
of negative stories in the media and scrutiny from state and federal
regulators who focused on how the need for repairs is determined. MAP
was formed as an industry response to this issue.
Our 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 responsibility for
their vehicles - through proper, manufacturer-recommended,
maintenance. We encourage participatinf service and repair shops
(including franchisees and dealers) to adopt a Pledge to their
Customers and the Motorist Assurance Program developed Standards of
Service. All participating service providers have agreed to subscribe
to this Pledge and to adhere to the promulgated Standards of Service
which demonstrates 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 according to industry guidelines.
After learning that neither the car manufacturers nor any other source
had complete guidelines, leading industry organizations, along with
other industry participants banded together to address this
challenging task. During the past two and a half years, they
successfully developed industry inspection guidelines for the
following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical systems.
Guidelines for Drive Train and Transmision are currently being
promulgated. Revisions to the inspection guidelines for Exhaust,
Brakes/ABS and Steering and Suspension Systems, which were issued two
years ago, are now being published for implementation beginning spring
1997. Participating shops utilize these Uniform Inspection Guidelines
as part of the inspection process and for communicating their findings
to their customers.
The Motorist Assurance Program continues to work
* BRAKE SYSTEM UNIFORM INSPECTION GUIDELINES *
Article Text (p. 2)
1990 Volkswagen Corrado
For Volkswagen Technical Site: http://vw.belcom.ru
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
concerned with auto repair and/or consumer protection are conducted.
Feedback from these representatives are brought back to members, 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 arbitration through MAP/BBB-CARE in cooperation with the
Council of Better Business Bureaus and individual participating
Bureaus. MAP "piloted" in Indianapolis and Pittsburgh during spring,
1996 - and publicized "roll-outs" in New Jersey, Detroit (MI), Chicago
(IL) and Richmond (VA) were conducted. To put some "teeth" in the
program, and 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. In
addition, a committee of service providers had been working diligently
developing standards for newspaper, television and Internet
advertising.

with your support, both the automotive repair industry and your
customers will reap the benefits. Please visit MAP at our Internet

A customer, of course, has the choice of whether or not a
shop will service his or her vehicle. He or she may decide not to
follow some of your suggestions. When a customer declines to authorize
a service or repair indicated in the MAP Uniform Inspection Guidelines
as "required," a MAP shop may refuse service on that system, if
proceeding with the work could create or continue an unsafe or
unsatisfactory condition.
The following reasons may be used for required and suggested
services. These codes are shown in the "Code" column of the Uniform
Inspection Guidelines that follow.
PART REPLACEMENT CODE IDENTIFICATION
NOTE: Refer to the following tables for definitions of the codes
listed in the condition/procedure tables for the specific
components that may need to be replaced.
SERVICE PROCEDURES REQUIRED & SUGGESTED FOR PROPER
VEHICLE OPERATION
The brake system is the single most important safety feature
of any passenger vehicle. It is absolutely vital that proper
procedures and preventive maintenance are offered and suggested to
consumers to prevent very costly, and in some cases, catastrophic
brake system failure.
NOTE: Some states may have specifications that differ from OEM.
Check your local/state regulations. Where state or local laws
are stricter, they take precedence over these guidelines.

for the brake system is stamped on the master cylinder cover.
It is suggested that the system should be flushed and
refilled with correct brake fluid when performing hydraulic brake
service.
NOTE: (1) If a fluid other than specification brake fluid is present
in the brake system, the required service is to flush and
fill with the correct brake fluid.
(2) If a fluid other than brake fluid is present in the brake
system which DOES affect the rubber parts, the required
service is to: a) remove all components having rubber parts
from the system, b) flush lines with denatured alcohol or

Determine the need to recondition based upon individual drum
conditions that follow. Friction material replacement does not require
drum reconditioning unless other justifications exist. DO NOT
recondition new drums unless they are being pressed or bolted onto an
existing hub. It is not necessary to replace drums in axle sets.
However, when replacing or reconditioning a drum due to the conditions
that follow, you may suggest reconditioning of the other drum on the
same axle to eliminate uneven braking behavior. Determine the need to
replace based upon the individual drum conditions that follow. Always
wash drums after servicing or before installing.
NOTE: (1) If failure to build pressure is traced to the pump or motor,
require replacement.
(2) If excessive run time is traced to the pump or motor,
require replacement.
Many modulators can only be replaced as complete assemblies.
Whenever possible, replace the failed component part. If replacement
of the failed part is not possible, then replace the modulator
assembly.
NOTE: (1) Check for possible vacuum leak at booster input seal and/or
push rod misalignment as possible causes. If neither is the
cause, require repair or replacement of master cylinder.
(2) This condition may be normal on some vehicles equipped with
anti-lock brakes. If all other possible causes have been
eliminated, require repair or replacement of master
cylinder.
(3) Require repair or replacement of valve if possible. If not
possible, require replacement of the master cylinder.
(4) DO NOT replace master cylinder unless it exhibits conditions
listed for replacement. You may suggest fluid change
according to OEM service intervals.
(5) Use hose clamp test to determine this condition. Use an
* BRAKE SYSTEM UNIFORM INSPECTION GUIDELINES *
Article Text (p. 21)
1990 Volkswagen Corrado

approved brake hose clamp to avoid damage to the hose.
(6) This condition may indicate contaminated brake fluid. See
Brake Fluid section of the Uniform Inspection Guidelines.
Determine the need to recondition based upon individual
rotor conditions that follow. Friction material replacement does not
require rotor reconditioning unless other justifications exist. DO NOT
recondition new rotors unless they are being pressed or bolted onto an
existing hub. It is not necessary to replace rotors in axle sets.
However, when replacing or reconditioning a rotor due to the
conditions that follow, you may suggest reconditioning of the other
rotor on the same axle to eliminate uneven braking behavior.
Determine the need to replace based upon the individual rotor
conditions that follow. Reconditioning is defined as machining and
block sanding, or block sanding only. Block sanding is defined as
using 120-150 grit sandpaper with moderate to heavy force for 60
seconds per side. Always wash rotors after servicing or before
installing.
Rotor thickness will be ³ A ³ Require replacement.

NOTE: (1) Examples of severe corrosion are: composite plate separated
from friction surfaces and cooling fins cracked or missing.
(2) If OEM does not supply "machine to" specifications, you may
machine to discard specifications.
(3) Scoring is defined as grooves or ridges in the friction
contact surface. Some vehicle manufacturers require
machining when scoring exceeds their allowable
specifications.

Standards For Automotive Repair
All Makes and Models
INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
The Motorist Assurance Program was formed in 1992 by forty
(40) companies who were concerned about the image of automotive
service establishments. Today, MAP is an industry-wide association
dedicated to strengthening consumer satisfaction with the automotive
repair industry. MAP's participants represent the majority of the
nation's multi-bay retail automotive outlets, their parts and
equipment suppliers, independent repair shops, industry associations,
car companies, manufacturers representatives, and the trade press. MAP
is developing standards of service, uniform inspection procedures
and other programs to assure consumers of the industry's
professionalism and the commitment to excellence shared by MAP's
sponsoring companies.
MAP's achievements to date include production and
distribution (over 280,000) of the consumer brochure "How to Find Your
Way Under the Hood and Around Your Car", development of a Pledge of
Satisfaction to Consumers and Standards of Service and establishment
of relationships with regulatory agencies.
As auto repair becomes an issue for federal and state
regulators, MAP is working to educate government leaders on the
dynamics of automotive service and the self-monitoring efforts MAP
has undertaken on the industry's behalf. MAP's sponsoring companies
are becoming well-known to government representatives as exemplary
businesses working to improve the industry. Media sources also look to
MAP to provide information and advice to consumers and on working with
automotive technicians and repair establishments.
In the next few months, MAP plans to assist member repair
facilities in implementing the MAP Pledge to Customers, establishing
an alternate dispute resolution system to help resolve customer
complaints within the industry, and developing a shop accreditation
program to encourage policies in concert with the MAP Standards of
Service and Inspection Guidelines.
MAP has united the aftermarket behind its consumer-oriented
goals and has established itself both within and outside of the
industry. We welcome you to join us as MAP continues its outreach.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF SERVICE REQUIREMENTS & SUGGESTIONS
It is MAP policy that all exhaust, brake, ABS, steering and
suspension, wheel alignment, tires and wheels, driveline, engine
performance and maintenance and heating, ventilation and air
conditioning services be offered and performed under the guidelines
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 needs expressed by
the customer.
This section lists the various parts and conditions that
indicate required or suggested service or part replacement. Although
this list is extensive, it is not inclusive. In addition to this list,
a technician may make a suggestion. This suggestion must be based on
substantial and informed experience or the vehicle manufacturer's
recommended service interval.
Some conditions indicate that service or part replacement
is required because the part in question is no longer providing
the function for which it is intended, does not meet a vehicle
manufacturer's design specification or is missing.
* Example: An exhaust pipe has corroded severely and has a hole
in it through which exhaust gases are leaking. Replacement of
the exhaust pipe in this case is required due to functional
failure.
* ELECTRICAL SYSTEM UNIFORM INSPECTION GUIDELINES *
Article Text (p. 4)
1990 Volkswagen Corrado
For Volkswagen Technical Site: http://vw.belcom.ru
* Example: A brake rotor has been worn to the point where it
measures less than the vehicle manufacturer's specifications.
Replacement of the rotor is required because it does not meet
design specifications.
Some conditions indicate that a service or part replacement
is suggested because the part is close to the end of its useful life
or to address a customer's need, convenience or request. If a
customer's vehicle has one of these conditions, the procedure may only
be to suggest service.
* Example: An exhaust pipe is rusted, corroded or weak, but no
leaks are present. In this case, the exhaust pipe has not
failed. However, there is evidence that the pipe may need
replacement in the near future. Replacement of the pipe may
be suggested for the customer's convenience in avoiding a
future problem.
* Example: The customer desires improved ride and/or handling,
but the vehicle's shocks or struts have not failed. In this
case, replacement may be suggested to satisfy the customer's
wishes. In this case, replacement of the shocks or struts may
not be sold as a requirement.
A customer, of course, has the choice of whether or not a
Shop will service his or her vehicle. He or she may decide not to
follow some of your suggestions. The following reasons may be used for
required and suggested services:
Reasons to Require Repair or Replacement:
* component no longer performs intended purpose
* component does not meet a design specification (regardless of
performance)
* component is missing.
Reasons to Suggest Repair or Replacement
* component is close to the end of its useful life (just above
discard specifications or weak; failure likely to occur soon,
etc.)
* address a customer need, convenience or request (stiffen
ride, enhance performance, eliminate noise, etc.)
* comply with maintenance recommended by the vehicle's Original
Equipment Manufacturer (OEM)
* technician's recommendation based on substantial and informed
experience.

Proper operation of any electrical system component can be
affected by battery condition. The battery(ies) must meet or exceed
minimum specification for vehicle as equipped and test to that
specific battery's CCA. Before condemning any component, test vehicle
following OEM test and diagnostic procedures.
A battery should meet or exceed the intended vehicle's OEM
(Original Equipment Manufacturer) specifications with regard to Cold
Cranking Amps for that specific vehicle. A battery should be tested
using the test procedures outlined by Battery Council International
(BCI) - an association of battery industry companies whose members
establish policy and standards for the industry and/or the
manufacturer of the battery,
DEFINITION OF TERMS
Cold Cranking Amp (CCA) Rating - The number of amperes a new,
fully charged battery at 0øF (-17.8øC) can deliver for 30 seconds and
maintain at least a voltage of 1.2 volts per cell (7.2 volts for a 12
volt battery).
Cranking Amps (CA) - The number of amps a new, fully charged
battery, typically at 32øF (0øC), can deliver for 30 seconds and
maintain at least a voltage of 1.2 volts per cell (7.2 volts for a
12 volt battery).
Hot Cranking Amps - A rating (non-recognized by BCI) used
by some battery manufacturers for testing purposes based on 80øF (26.
7ø C).
OEM Cranking Amps - A number indicating the amount of amps
(current) at 0ø recommended by the vehicle manufacturer intended to
meet the starting requirements for a specific vehicle.
Fails to Accept and Hold a Charge - This term refers a
battery that fails to either accept and/or retain a charge using
appropriate times listed in the Battery Charging Guide section of the
BCI Technical Service Manual or battery manufacturer's specifications.
BATTERY LOAD TESTING
* Battery Load Testing requirements should be tested at vehicle
OEM specifications or battery CCA specifications for pass/
fail criteria using the highest rating.
* Battery Load Testing and OEM specifications are based on
testing at the CCA level only. When a battery is rated at any
other given temperature (32øF or 80øC), the battery rating
should be converted to a corresponding CCA for testing

The mission of the Motorist Assurance Program (MAP) is ...
To promote trust and the assurance of customer satisfaction in the
vehicle repair industry through education and the creation of industry
guidelines. In continuing to fulfill its mission, MAP will be
establishing a facility accreditation procedure to provide customers
with some assurance that standards of service are being followed
throughout the industry, and that when those standards are not met,
there is a method for the customer to achieve satisfaction.
A repair facility which commits to participate in the program
will be permitted to display the MAP Facility Accreditation Program
sign. Display of the sign will notify the consuming public that they
can have confidence in the inspection performed at the facility, and
that any dispute over repairs or service will be resolved fairly.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program (MAP) 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.
The Motorist Assurance Program was established as an
industry-wide effort to address concerns raised by regulators, the
media and consumers questioning our ethics and methods of doing
business. The automotive repair industry had been bombarded by months
of negative stories in the media and scrutiny from state and federal
regulators who focused on how the need for repairs is determined. MAP
was formed as an industry response to this issue.
Our 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 responsibility for
their vehicles - through proper, manufacturer-recommended,
maintenance. We encourage participatinf service and repair shops
(including franchisees and dealers) to adopt a Pledge to their
Customers and the Motorist Assurance Program developed Standards of
Service. All participating service providers have agreed to subscribe
to this Pledge and to adhere to the promulgated Standards of Service
which demonstrates 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 according to industry guidelines.
After learning that neither the car manufacturers nor any other source
had complete guidelines, leading industry organizations, along with
other industry participants banded together to address this
challenging task. During the past two and a half years, they
successfully developed industry inspection guidelines for the
following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical systems.
Guidelines for Drive Train and Transmision are currently being
promulgated. Revisions to the inspection guidelines for Exhaust,
Brakes/ABS and Steering and Suspension Systems, which were issued two
years ago, are now being published for implementation beginning spring
1997. Participating shops utilize these Uniform Inspection Guidelines
as part of the inspection process and for communicating their findings
* ENGINE SYSTEMS UNIFORM INSPECTION GUIDELINES *
Article Text (p. 2)
1990 Volkswagen Corrado
For Volkswagen Technical Site: http://vw.belcom.ru
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
concerned with auto repair and/or consumer protection are conducted.
Feedback from these representatives are brought back to members, 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 arbitration through MAP/BBB-CARE in cooperation with the
Council of Better Business Bureaus and individual participating
Bureaus. MAP "piloted" in Indianapolis and Pittsburgh during spring,
1996 - and publicized "roll-outs" in New Jersey, Detroit (MI), Chicago
(IL) and Richmond (VA) were conducted. To put some "teeth" in the
program, and 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. In
addition, a committee of service providers had been working diligently
developing standards for newspaper, television and Internet
advertising.
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
