Bulletin Summary
Emissions Recall. General Motors has decided to conduct a voluntary emissions recall involving certain vehicles. The engine control module (ECM) in these vehicles may not be able to properly diagnose reduced efficiency issues within the catalytic converter. If the catalytic converter?s efficiency would become reduced, tailpipe emissions could exceed acceptable standards without illuminating the Malfunction Indicator Lamp (Check Engine Light). Dealers are to reprogram the ECM.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
