Thanks for the reply. Yes I checked all plugs, fuses and relays (one fuse behind drivers coin draw, one fuse and one relay in engine bay fuse box by the battery) and all connectors to the steering unit at the back.Took them all out, cleaned and put back. It didn't make a difference sadly. I haven't looked on the steering rack, will do that today, thanks.
That's whats odd about it, it throws errors when plugged in, but the HICAS dash light doesn't stay on or anything. It does come on initially like all the other lights do when the ignition it turned but goes off along with the rest, so the bulb hasn't been pulled...
