provide diagnostic information as well as a completed

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.

service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
