ACC/CMS Error
Yesterday our 2022 Allegro Bus 45opp experienced a fault with the ACC/CMS system. Adaptive Cruise Control and Collision Mitigation System. After 5 miles of driving we got the following on the dash display. It continued to beep for over an hour until we managed to talk to Tiffin. We were directed to a fuse in the drivers compartment F5. It's a 5 amp fuse and it's ok. When removed the beeping stopped!! but the fault remained plus adding an ABS fault to go with it.
So We're at our destination now and I want to fault find. Any advice where to look would be welcomed. The diagnostics codes are shown below. Does this unit need recalibrating? If so, how?
I have removed the unit from the front of the bus and checked and cleaned the connectors. Also cleaned another connector above the generator. I have had some assistance from the Allegro Bus group but the fault remains.
