Warranty Coverage Change for Emission-Related Reprogramming Events (PCM, ECM and TCM)
TECHNICAL SERVICE BULLETIN
| Affected Model(s): | 2005 and Prior GM Passenger Cars and Trucks; 2003-2004 HUMMER H2 |
Service Information
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).
