Service bulletin SFCC_OCT2020_34

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.

NHTSA's summary

P249D-00 DEF Dosing Adaptation Factor (trim) too high flags at key on after attempting to reset the DEF Dosing Adaptation Factor. Vehicle states it passes the routine, but the code recurs at key-on.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
