    There is a fault.   Even a ghost code will be registered.

    Don't know if my comment will help. I had a similar problem once and did the simple checks first. I found I had failed to check my engine oil late in the season. The level was just a tad low and needed to be topped off with a half quart I had on board. Solved the problem and no more alarm but now I check it every week.
