1. Engine, Transmission, Transfer Case,
Rear Axle Components and Catalytic
Converter Failures Due to Non-GM ECM
Calibrations Being Installed
Notice:
•Be advised that GM REQUIRES retrieving the
Calibration Information and performing the
Calibration Verification Procedure as outlined
in this Bulletin, whenever diagnostics
determine a hard part failure may have
occurred on internal engine parts and BEFORE
disassembly, repair or replacement of an
engine assembly under warranty.
• Be advised that GM strongly recommends
retrieving the Calibration Information and
performing the Calibration Verification
Procedure as outlined in this Bulletin,
whenever diagnostics determine a hard part
failure may have occurred on transmission,
transfer case or rear axle components and
before disassembly, repair or replacement of a
transmission, transfer case or rear axle
assembly under warranty. It is also
recommended that the ECM Calibration
Verification Procedure be performed whenever
diagnostics determine that catalytic converter
replacement is necessary.
• It is not a requirement to verify transmission
control module calibrations on gasoline engine
applications.
General Motors is identifying an increasing number of
engine, transmission and catalytic converter part
failures that are the result of non-GM ECM calibrations
being installed.
When alteration to the GM-released ECM calibration
occurs, it subjects powertrain and driveline components
such as engine, transmission, transfer case, driveshaft
and the 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
ECM calibration is subsequently removed.
Warranty coverage is based on the equipment and
ECM 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 that are different from those
tested and released by GM can damage and/or weaken
components, leading to poor performance and/or
shortened life.
Additionally, non-GM issued ECM modifications often
do not meet the same emissions performance
standards as GM issued calibrations. Depending on
state statutes, individuals who install ECM 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 Retrieval and
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.
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.

1. Engine, Transmission, Transfer Case,
Rear Axle Components and Catalytic
Converter Failures Due to Non-GM ECM
Calibrations Being Installed
Notice:
•Be advised that GM REQUIRES retrieving the
Calibration Information and performing the
Calibration Verification Procedure as outlined
in this Bulletin, whenever diagnostics
determine a hard part failure may have
occurred on internal engine parts and BEFORE
disassembly, repair or replacement of an
engine assembly under warranty.
• Be advised that GM strongly recommends
retrieving the Calibration Information and
performing the Calibration Verification
Procedure as outlined in this Bulletin,
whenever diagnostics determine a hard part
failure may have occurred on transmission,
transfer case or rear axle components and
before disassembly, repair or replacement of a
transmission, transfer case or rear axle
assembly under warranty. It is also
recommended that the ECM Calibration
Verification Procedure be performed whenever
diagnostics determine that catalytic converter
replacement is necessary.
• It is not a requirement to verify transmission
control module calibrations on gasoline engine
applications.
General Motors is identifying an increasing number of
engine, transmission and catalytic converter part
failures that are the result of non-GM ECM calibrations
being installed.
When alteration to the GM-released ECM calibration
occurs, it subjects powertrain and driveline components
such as engine, transmission, transfer case, driveshaft
and the 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
ECM calibration is subsequently removed.
Warranty coverage is based on the equipment and
ECM 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 that are different from those
tested and released by GM can damage and/or weaken
components, leading to poor performance and/or
shortened life.
Additionally, non-GM issued ECM modifications often
do not meet the same emissions performance
standards as GM issued calibrations. Depending on
state statutes, individuals who install ECM 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 Retrieval and
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.
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
