    Anyone know how to reset the AVH system?

    I pulled my battery out to check the date code on it. I followed the detailed procedure for changing the battery that is published elsewhere in this forum. Now I am getting an AVH failure warning. I played with the parking brake control until the "Brake" indicator went off. Then I drove about 3 miles and it drove fine. No brake drag or anything noticeable.

    I doubt there is any hardware problem because this was triggered by having the battery disconnected. I think that I just need to reset the software.

    A third start cycle after each time giving in a minute in position II before hitting the start button seems to have cleared it. 458s are really finicky about loosing battery power. I think my battery is old so I am going to get a new one soon, so this was practice. I will see then if it does the same thing.

    Common for the dash to become a "Christmas tree of colorful lights" if the battery is not near 100%. I bought an Autel scanner that has some pretty in depth Ferrari coverage and a scan showed multiple codes in many modules that had no affect on the car that I could detect. The first time this happens is terrifying. Glad you resolved this and thank you for the follow up.
