• Any component listed in a current parts restriction.
• A current assembly exchange program.
The Service Department Personnel should review the applicable documents related to the Part Restriction or
Exchange Program and be prepared to provide diagnostic information.
Customer Satisfaction
There may be situations where an assembly can be repaired, but due to customer satisfaction reasons an assembly
replacement should be considered. In these cases the service department personnel should review the concern with
the District Manager Aftersales (DMA), in Canada the District Manager - Customer Care and Service Process
(DM-CCSP).
For Service Agents required to contact the PQC, the service department personnel MUST be prepared to provide
diagnostic information as well as a completed repair/replacement estimate portion of the Cost Comparison
Worksheet for Assembly Repair vs Replacement. Service Agents required to contact the PQC, MUST advise the
PQC when the DMA, in Canada the DM-CCSP authorizes the replacement of an engine, transmission or transfer
case assembly for Customer Enthusiasm purposes versus repair.
Service Agents Working With PCC (United States Only)
All Service Agents that are working with the PCC to reimburse Independent Service Centers (ISC) must continue to
follow the existing PCC processes.

PQC Process
Before Calling PQC
If diagnosis performed by the service department personnel indicates a need for an engine, transmission or transfer
case assembly replacement, Service Agents required to call PQC must perform the following actions PRIOR to
replacement and BEFORE contacting PQC:
• Complete the Calibration Verification Number process as outlined in the latest version of:
– Corporate Bulletin #14-06-04-003: Identifying Non-GM ECM Calibration Use and Power-up Hardware
Detection in Duramax Diesel Engines Using GDS 2
– Corporate Bulletin #08-06-04-006 for Duramax® Diesel Engines
– Corporate Bulletin #09-06-04-026 for Gasoline Engines / Transmissions
• For automatic transmissions only, perform a transmission cooler flush and record the code.

•

The Condition and Cause including any diagnostic trouble codes (DTCs), symptoms, Scan Tool Snapshots and
any other useful information observed and recorded by the technician. The technician must have detailed
information required for proper root cause analysis and product concerns correction. This information is very
valuable in ensuring that the replacement assemblies and current production parts help to continually improve
our products.
• Record the serial number of the failed assembly.
• Complete a Cost Comparison Worksheet for Assembly Repair vs Replacement. For help in locating this form,
see the following section titled: Cost Comparison Worksheet for Assembly Repair vs Replacement On
GlobalConnect (U.S.)
• Complete the Repair Estimate: Replacement Component Assembly Estimate: section for the assembly
category included in the Cost Comparison Worksheet for Assembly Repair vs Replacement. Accurate repair
versus replacement cost estimates (include the markups) are ESSENTIAL in order to eliminate a second call
to the PQC.
• Have the Job Card number, VIN and the Service Agent BAC code ready when calling the PQC along with a
detailed Customer Concern.
We are requesting that ALL service technicians use this opportunity to help GM better understand how and why a
given component failed. For GM this is an opportunity to have direct and thorough feedback from the technician to
provide to Engineering and thus improve the reliability and durability of both OEM and Genuine GM Parts
assemblies.
