Mitsubishi Montero (1991+). Manual — part 45

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 addresses a customer’s need, convenience or request. If a

customer’s vehicle has one of these conditions, the procedure may be

only 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. When a repair is required, a MAP

shop must refuse partial service on that system if, in the judgment of

the service provider, proceeding with the work could create or

continue an unsafe condition. When a procedure states that required

or suggested repair or replacement is recommended, the customer must

be informed of the generally acceptable repair/replacement options

whether or not performed by the shop.

When presenting suggested repairs to the customer, you must

present the facts, allowing the customer to draw their own conclusions

and make an informed decision about how to proceed.

The following reasons may be used for required and suggested

services. These codes are shown in the "Code" column of the MAP

Uniform Inspection & Communications Standards that follow:

Reasons to Require Repair or Replacement

A - Part no longer performs intended purpose

B - Part does not meet a design specification (regardless of

performance)

C - Part is missing

NOTE: When a repair is required, the shop must refuse partial

service to the system in question, if the repair creates

or continues an unsafe condition.

Reasons to Suggest Repair or Replacement

1 - Part is close to the end of its useful life (just above

discard specifications, or weak; failure likely to occur

soon, etc.)

2 - To address a customer need, convenience, or request (to

stiffen ride, enhance performance, eliminate noise, etc.)

3 - To comply with maintenance recommended by the vehicle’s

Original Equipment Manufacturer (OEM)

4 - Technician’s recommendation based on substantial and

informed experience

NOTE: Suggested services are always optional. When presenting

suggested repairs to the customer, you must present the

facts, allowing the customer to draw their own conclusions

and make an informed decision about how to proceed.

ANTI-LOCK BRAKE SYSTEMS

NOTE: Anti-lock brakes are an integral part of the brake system. It

is essential that the anti-lock brakes function properly when

brake service is performed.

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).

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.

NOTE: Intermittent electrical conditions are often caused by a loss

of ground, poor connection, or water intrusion into the

wiring harness.

NOTE: Electro-magnetic interference (EMI) may be caused by

incorrect installation of accessories or components. EMI can

result in improper system operation.
