Hey

I have a ducati 800 SS from 2005 and I am having problems with programming my bike. I only have the red key and the code card, and when i try to power it up, it gives me the "no valid key" error. I have tried to program it, but it only accept the code once. When I take the key out and tries the second time I needs to be programmed again.

It all startet after i unfortunately reversed the battery poles. I know, I am a idiot.

Does eneryone know whats wrong?

Hmmmm....It sounds like you have damaged the internal ground on the ECU. Some folks have had success overcoming this blown ground by making a jumper cable and attaching it to the ground pin in the ECU diagnostic plug under the seat. The permanent fix, unfortunately, is a new ECU.

Check out this post. It's good to start at the beginning and read through.
