ECU went into 'diagnostic mode' NEED HELP
I was updated my BB flash and my computer shut down in the middle of a write.
I restarted the computer re-plugged in and now my ECU is in Diagnostic Mode and wont start, JB4 wont come on and I cant re-load the original flash or new flash. How fucked am I what can I do to get this to work again?
