Make sure you have the battery fully charged (at least 8 hours with a 10 amp charger) and try over if you don't get any more messages erase all the codes.

Re: dead battery and codes (awalters)
Clear the codes and hopefully you will be OK. Sometimes a fully discharged battery will not take a good/complete charge and will have to be replaced. Check it out and if you have any problems, take to your dealer and get a new one. :yesnod: :) BTW, NEVER store your car with the battery still connected. Use a Battery Tender for short down times. :thumbs:

Re: dead battery and codes (fast4vette)
i have seen bogus codes pop up with reconnecting a battery.
just clear them and you should be fine.
it's no big deal.
