You need to know the exact fault code numbers. There's a bunch of them, and they mean very different things. When you have a lot of codes suddenly show up at the same time, look for what they have in common. In this case the wiring harness is a real good suspect. Look for wires that fell down onto hot exhaust parts, or corroded connector terminals.
