Agree with BRG check menu 1 sub-menu 3 and make sure it's set to anything but 0 for the time being to see if you can get the car to run on inspection. A 0 means not a hydro, a traction. I've experienced too many times when a "fast fingered freddy" has gone in and changed a parameter without realizing it and when the power is cycled, on the KCM's that's when parameter changes are put into effect, like a power outage. I believe there's about 7 different hydro options for sub-menu 3 that are for hydro's depending on the type so that can be determined later if that's the issue. I have some info on how to perform the startup of the hydro's if you want to PM me but not alot other than a few versions of wiring diagrams.
