Identifying Non-GM (Aftermarket) Engine and Transmission Calibrations for V8
Gasoline Engines Using Tech 2® or Global Diagnostic System 2 (GDS 2)
Models:
2006-2013 GM Passenger Cars and Light Duty Trucks
Equipped with V8 Gasoline Powered Engines Only
Attention: This bulletin applies to V8 gasoline powered engines ONLY. For Duramax™
diesel powered engines, refer to the latest version of Corporate Bulletin
Number 08-06-04-006. Please, always refer to the GM Service Policy and Procedures
Manual — Article: 1.2.2.12 for the latest GM Policy and Procedures Information.
This bulletin is being revised to add additional text to the “Attention” statement and to advise
the Service Department Personnel that they must always refer to the GM Service Policy and
Procedures Manual Article: 1.2.2.12 for the latest GM Policy and Procedures Information.
Please discard Corporate Bulletin Number 09-06-04-026D
(Section 06 – Engine/Propulsion System).
Notice: The PQC has a process to confirm the
ECM/PCM calibration is GM issued. BEFORE
authorizing any V8 gasoline engine replacement,
the PQC requires the Calibrations Group to verify
that the engine calibrations are OEM.
• The Calibrations Group will require a digital
picture (.jpg file only) from the Tech 2 ® of the
Vehicle Information- (Engine) Calibration ID
and Verification No. (number) screen,
according to the process that is outlined in this
bulletin.
• The Calibrations Group will require a screen
shot (.jpg file only) of the GDS 2 Calibration
History Events screen according to the
process that is outlined in this bulletin.
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 used.
When alteration to the GM-released engine or
transmission control 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 dealer warranty claim submissions
to any remaining warranty coverage, to the powertrain
and driveline components whenever the presence of a

non-GM (aftermarket) 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 procedure when using the
Tech 2® or GDS 2 to identify the presence of non-GM
(aftermarket) calibrations. GM recommends performing
this check whenever a hard part failure is seen 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 calibration verification
Page 2

procedure be performed whenever diagnostics
determine that catalytic converter replacement is
necessary.
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. Connect the Tech 2® to the vehicle.
2. Go to: Diagnostics and build the vehicle.
3. Select: Powertrain.
4. Select: Engine.
5. Select: Engine Control Module or PCM.
6. *Select: Module ID Information or I/M Information
System if the Module ID Information selection is
not available.
7. *If "I/M information System" was selected, it may
be necessary to select "Vehicle Information" in
order to display the calibration information.
⇒ If the CVN information is displayed as “N/A”, it
will be necessary to contact the TCSC at
1-800-828-6860 for English or 1-800-503-3222
for French to obtain the CVN information.

Notice: The Tech 2 Vehicle Information Calibration ID and Verification No. screen will differ
slightly depending on vehicle and model year.
8. Take a CLEAR digital picture of the Tech 2 ®
Vehicle Information screen showing the entire VIN,
(Engine) Calibration ID and Verification No.
(Numbers). Two examples of the Tech 2® Vehicle
Information - (Engine) Calibration ID and
Verification No. screens are shown. Retain the
printout information and the Tech 2® screen
photograph with the repair order.
Notice: All pictures MUST be sent as a .jpg file.
Keep all photos in ONE e-mail.
9. E-mail a copy of the picture to
[email protected]. In the Subject line of the
e-mail include the phrase “V8 Cal” as well as the
complete VIN and Dealer BAC.
In the Body of the e-mail, include the VIN,
mileage, R.O. number and BAC. Include a brief
description of the customer concern and cause of
the concern.
Notice: The dealer will receive an e-mail reply after
the calibrations have been validated. The e-mail
reply will advise the dealer if the calibrations
are OEM.
10. Allow two hours for the Calibrations Group to verify
the calibrations and set up the case details.
⇒ If the Calibrations Group determines that the
calibrations ARE aftermarket calibrations, DO
NOT contact GM Technical Assistance to
discuss warranty concerns on the aftermarket
calibrations. ALL questions and concerns about
warranty should be directed to the District
Manager Aftersales (DMA), in Canada the
DM-CCSP (District Manager-Customer Care
and Service Process).
The Calibrations Group will update the
appropriate PQC or TAC case with the results
of the V8 Calibration Verification request.

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.
