Service campaign CB748-1

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

Starting in May 12th, 2022, some truck units were manufactured without BlueBox due to supply chain constraints. The antenna and all necessary harnessing are not present. Not all units are required to have the BlueBox installed. This campaign will cover parts and installation for customer that request to have a BlueBox functionality. If a customer requests BlueBox functionality, dealers will need to order Installation kit (P/N 047345) for ST or (P/N 047346) for MT and BlueBox P/N 047342 per CSB044. Orders will be processed based on prioritization and allocation. Customer name must be entered when order is placed.

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.

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