Thanks Mike, Art and Jim, I have made myself a blink code tool and have a book to read the code for the ACC on my 300 SDL.

I am not sure of a few things. Is the engine running to make the tests? Does a test have to be made with each of the ACC positions?

I hate to ask for a step by step procedure to follow, but it sure would help.

If this works, I'll feel like a cheat, heh, heh, but I'll get over it.

Thanks,
Harry 86 300 SDL
