Iveco Eurocargo 160E28 - Dodgy Electrics, Advice needed!

Thanks for watching everybody. This Eurocargo seems to drive ok, engine and brakes etc all work as they should, but its throwing a million codes, the ABS is not happy. speedometer doesnt seem to work, odometer is missing from the display altogether. I have heard about the place that these trucks have issues with wires rubbing together and creating shorts. more investigation is required.
