My answer may apply depending upon the build date of the chassis. The System III wiring system for gauges/indicators was used up through June 9, 2002. If the coach was built on a chassis that had been sitting for a while, this is possible. If your chassis build date is later than June 9, 2002 contact the Freightliner helpdesk for more up to date info. The symptoms you describe certainly sound like the the System III like what I have on my motorhome.
For diagnostic info on the System III, download the link below as it is a freightliner service bulletin on troubleshooting the system:
SB 54-12 (Freightliner)First of all, those lights chasing themselves around in a pattern is a classic symptom of low voltage. An alternator problem or a battery problem could cause this.
It could also be a bad link between the engine data bus and the VDC (Vehicle Data Computer). If data from the engine bus is not received by the VDC within 45 seconds, the MC (message center) will begin scrolling (initiate a chase pattern). When communication with the engine data bus is re-established, the system will begin to function normally (see page 6 of SB 54-12).
I hope this helps.
