Service bulletin N242441790
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
Service Update. On certain vehicles, equipped with a 3.0L diesel engine (RPO LM2), false failures could result in the check engine light to turn on intermittently, particularly in cold weather, during gentle or slow driving, and when both the front and rear HVAC systems are in use. Dealers are to reprogram the engine control module.
