Mercedes Atego 815 2000

Hi folks, not sure if I’m posting this in the right place, but here we go.

MY2000 Merc Atego 815. Driving today and simultaneously both the ABS warning light and the Cab tipped light came on. Obviously those mechanicals are not related so I’m thinking a wiring issue. Does anyone with knowledge of these vehicles know of any common wiring faults on these?

Thanks in advance.
