Service campaign N222383021

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

General Motors has decided to conduct an Emission Recall involving certain vehicles with a 3.0L diesel engine and non-ETRS transmission. The Engine Control Module (ECM) may not properly respond to certain service tool requests for the datafile CALID (part number) and CVN (checksum). This condition may cause a vehicle to fail an emissions Inspection/Maintenance (I/M) test. Dealers are to reprogram the Engine Control Module.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Vehicles listed
CHEVROLET SILVERADO 15002022 (the catalog's model; the bulletin names a series or trim of it)
GMC SIERRA 15002022 (the catalog's model; the bulletin names a series or trim of it)

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