Service bulletin CBR 2497 092025
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
Electronic control units on the VN(4), PR (4) and AN (4) contain information that is critical for vehicle functionality, maintaining vehicle life data, and maintaining vehicle compliance. Because of this, swapping ECUs from truck to truck even for diagnostic purposes may cause functional or compliance complications that may or may not be apparent.
The document
