If you want to understand how your dash lights (message center) work, go to this link and download the Freightliner Service Bulletin 54-12.

You can get assistance in diagnosing the problem from the Freightliner Help Desk (free service). 1 800 FTL HELP have the last 6 digits of your vin number available when you call.
