Hi, I've read the archives, but now I'm more confused, since talking to the "SUN" Modis hot line about not being able to communicate with the Rover 75 ECU,and not being able the turn back the service lights, I was told to join terminals 8 & 4 for either 1 - 4 secs. or 8 - 25 secs. with ignition on 2.This seems to conflict with the archive. So before I blow up the ECU, can some one out there help ? Is there a tool that I can buy ?
