Engine, Transmission, Transfer Case, Rear Axle Components and Catalytic Converter Failures Due to Non-GM
Engine and/or Transmission Control Module Calibrations Being Installed
Notice: Be advised that GM strongly recommends performing the Calibration Verification Procedure as outlined in this Bulletin, whenever
diagnostics determine a hard part failure may have occurred on internal engine, transmission, transfer case or rear axle components and BEFORE
disassembly, repair or replacement of an engine, transmission, transfer case or rear axle assembly under warranty. It is also recommended that
the engine control module Calibration Verification Procedure be performed whenever diagnostics determine that catalytic converter replacement
is necessary.
General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket)
engine and transmission control calibrations being installed.
When alteration to the GM-released engine or transmission control module calibrations occurs, it subjects powertrain and driveline components (engine,
transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the
potential to alter reliability, durability and emissions performance, that GM has adopted a policy that prevents any UNAUTHORIZED Service Agent warranty
Transaction submissions to any remaining warranty coverage, to the powertrain and driveline components whenever the presence of a non-GM calibration is
confirmed – even if the non-GM control module calibration is subsequently removed.
Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That’s
because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over
the life of the warranty coverage and beyond. Stresses resulting from calibrations different from those tested and released by GM can damage or weaken
components, leading to poor performance and or shortened life.
Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued
calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions
certification standards may be subject to fines and/or penalties.
This bulletin outlines the Calibration Verification Procedures for ALL Service Agents including Service Agents Not Required to Call PQC for
Powertrain/Drivetrain Assembly Replacement Authorization and Service Agents Required to Call PQC for Powertrain/Drivetrain Assembly Replacement
Authorization, using the Tech 2® or GDS 2 to identify the presence of non-GM control module calibrations.
1
If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty may be blocked and notated in
Global Warranty Management (GWM) and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper 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 information.
