    The seat moving back may be normal operation of the driver memory/preferences features. It can be set to recall memory settings when unlocked with the fob.

But after some of the comments above, I'll go back and look at it again.

    The manual is an official GM service manual. I have no way of knowing if it is pirated. Since it was sold by a reputable seller on eBay, I would hope that it is a legitimate copy.

    Moist,

    MOST of the time, the seat stays in the EXIT position, even after I unlock with the key fob. Once in a while, I come up to the car before unlocking it, and the seat will be in the forward position. The steering wheel may or may not have moved during this time.

    Sorry for getting things off track with these comments. I was just trying to explain why I thought that the 0410 code might be a fluke. Maybe I will open another thread about the "mysterious moving seat" some time later.

    ----------

    Ranger,

    Thanks for posting these drawings. They make things clearer.

    Bob

    Well, guys....after four days and a number of cold starts, the SERVICE ENGINE SOON light has not come on again. It probably will the next time I start it (LOL). Anyway, if it shows up again, I will be well prepared to attack it, thanks to the information that all of you have provided.

    Keeping my fingers crossed...

    Bob
