Bulletin Summary
Service Update. Certain vehicles may incorrectly report to test tools an active permanent status of Transmission Control Module (TCM) Diagnostic Trouble Code (DTC) P2781 (Downshift Switch Circuit High). This could cause the vehicle to not pass an emissions inspection test in jurisdictions that check the permanent status of DTCs as part of an emissions testing program. Reprogram the TCM with updated software.
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.
