The battery thats there measured 12.8v at AutoZone. It just finished charged at that time.

Any input on these codes?

Clear them and re scan to see what comes back. They are power supply codes giving a notion that battery power was cut to the modules at some point but there are no over or under voltage codes either so I can't it's 100% alternator problem

Looks like your program isn't communicating with the car.

I dont know if this helps, but at first i was getting the AIRBAG light and the SEATBELT light on. The day the car died, I had it on the HIGH setting while I wash the wheel well. I drove to the store and it didnt go down. I noticed it didnt go down so I manually lowered it. Went in the store and came back out and it shut down while idling. My cousin was sitting in the car so I didnt shut it off.

I got it started and drove home. While sitting in the driveway, it shut down again. I got it started one more time and it shut down again after a few minutes.

I did notice that the positive terminal was loose.

This just a back trace of unusual events.

I am charging the battery as we speak with a CTEK MUS 4.3 charger. I dont know how long it will take to charge but im going to give it some time.

so would that mean i need a new computer?

No, it may mean that you need to go back and check to make sure all the parameter for the software matches the computer. What is the serial/usb port you are using?

I understand what you meant now. I did get some error message because the battery voltage was low at the time.I ran the test twice. i didnt get any error the first time I ran it. I also didnt take a picture of the codes the first time. However, some of those codes I posted are the same as the first time.

I will run the codes again once I get the battery fully charged.
