Service bulletin sb54122

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.

FREIGHTLINER: ON SOME VEHICLES EQUIPPED WITH THE ICU4M INSTRUMENT PANEL AND THE EATON VORAD SYSTEM WITH AN INTEGRATED ICU DISPLAY, THE DRIVER MESSAGE CENTER MAY NOT DISPLAY AN VORAD INFORMATION, EVEN THOUGH VORAD IS FUNCTIONING. THIS IS BECAUSE THE ICU4M IS NOT RECOGNIZING THE VORAD SYSTEM, DUE TO EITHER SOFTWARE CODING SEQUENCES DURING PRODUCTION, OR AN AFTERMARKET INSTALLATION OF THE VORAD OPTION.
