Well, I was able to fix the problem. The Mitchell on-demand shop manual
CD says that 50% of ACC fault codes were caused by user programming. Not
having done any programming (or not to my knowlege anyway), I was not
sure if this would fix it. So I reset the programming by holding the
Auto and Blower motor speed down buttons simultaneously.
That fixed it.
I think most of the ACC units in the 9-3 and 9-5 models behave
similarly, so this may help someone else.
