1. It is MAP policy that before any service is preformed on a vehicle, an inspection of the appropriate system must be performed; the condition of the component, codes and procedures are determined according to the Uniform Communication & Inspection Standards.
2. The results of the inspection must be documented on an inspection form and explained to the customer. The inspection may indicate that service or parts replacement are "Required" because the part in question is no longer providing the function for which it is intended, or does not meet the vehicle manufacturer's recommended design. The inspection may indicate that service or parts replacement are "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 to only suggest service.
3. A customer, of course, has the choice of whether or not a shop will service their vehicle. He or she may decide not to follow some of your recommendations. However, when a repair is "Required" a MAP Participating 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.
