I have recently changed the IRD (surprise, surprise) on my 1998 XEDI and now have the these 3 Amigos lit. I don't think there's a problem with the systems as the HDC works as long as i don't exceed about 9mph, which is when the system does a self check - i think. I believe that the system has registered a permanent fault when the IRD was removed as the wheels were turn independantly. Has anyone any idea how to reset these without going to a main dealer (can't find any local garages that have the correct equipment to reset the codes, just to read them.
