Service campaign S4254 202412

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

Certain Volvo VN (4) model trucks built with three flexible switch panels did not receive the correct parameters for the switch panel assignments. Some switches for features such as height control, axle load distribution, and auxiliary functions may not work as intended.
