WARRANTY ADMINISTRATION
Subject:
Warranty Coverage Change for Emission-Related Reprogramming Events (PCM, ECM and TCM)
Models:
2005 and Prior GM Passenger Cars and Trucks
In the past, all calibrations for vehicle controllers (PCM, ECM and TCM) were covered under the New Vehicle Limited Warranty (3 years/36,000 miles (60,000 km)). Effective immediately, the coverage for emission-related reprogramming now has the same coverage as the controller under the emission warranty.
Reprogramming that is NOT emissions-related will continue to be covered for 3 years/36,000 miles (60,000 km). Emissions-related calibrations will be announced through a GM Technical Service Bulletin with specific guidelines of coverage for each model affected. A special emission-related reprogramming labor operation has been developed. The labor operation to be used for claims relating to emission-related reprogramming is J6353 and will only be referenced in the bulletins addressing emission-related calibrations.
Example:
The PCM on 2004 model light duty vehicles is covered by the emission warranty for 8 years/80,000 miles (130,00 km). If GM released an "emission-related" calibration update for one of these vehicles, this reprogramming event would also be covered for 8 years/80,000 miles (130,000 km). If GM released a driveability-related calibration update (for example, to eliminate a hesitation) for one of these vehicles, this reprogramming event would be covered for 3 years/36,000 miles (60,000 km).
An emission calibration for medium duty and diesel applications are now also covered by the emission warranty that is applicable to that vehicle's controller.
Example:
The PCM on 2004 model medium duty vehicles is covered by the emission warranty for 5 years/50,000 miles (80,000 km).
If GM released an "emission-related" calibration update for one of these vehicles, this reprogramming event would also be covered for 5 years/50,000 miles (80,000 km).
