Dealership Service Management Responsibility
Important: There may be situations where an assembly can be repaired, but due to customer satisfaction reasons, an assembly replacement should be considered. The dealership should still be prepared to provide the Product Quality
Center (PQC) with the information on the diagnosis. In these cases, the dealer service management should contact the PQC. The PQC will contact the dealer's Area Service Manager (AVM) (in Canada, the District Service Manager (DSM)). The AVM/DSM then should communicate
back to the PQC that they have approved the assembly replacement. Then the PQC can contact the dealership to advise them of the AVM's/DSM's decision and to approve the warranty claim. Please reference Service Bulletin 02-07-30-029I for complete details on the
PQC engine replacement process.
