Service bulletin REC15503

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.

Emergency vehicle calibration will reduce the engine exhaust soot levels that enter the aftertreatment system and prevent the possibility of engine derate or eventual shutdown due to lack of performing exhaust system regeneration as a result of extensive idling typical of emergency vehicles.
