12. Warranty Information
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.
