Service bulletin C2643A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

This Campaign authorizes certified service locations to replace the engine dataplate and the Engine Control Module (ECM) dataplate, and update the ECMs through INSITE. This is an update to a previously submitted communication.
