Did I goof up on the install or something?

[Welcome to NBA Jam]

Well first thing to do is to figure out what the codes are.

Check if you dislodged your dislodged the small connector on your positive cable. The one that clamps directly to the positive terminal on the battery. There is a little connector that sometimes gets pulled off.

yea like someone said, the positive battery cable has a small explosive charge that fires when you are in an accident, to disconnect power. You probably didn't hook that small connector back up right.

Is it a black connector with red and black wire?

Look at the connector on the top left corner of the battery in this pic and see if there is a loose connection at the red positive terminal block. You can see sheathed wires (Blue and Brown) going to it. ***NOTE***This is not my picture. I am just using for reference. Thanks

I check all the other connection and everything is secured. However, I do remember accidentally disconnecting the blue connecter on the top right corner by accident on the install though

[Abacus38]

Never mine I found the wire you were talking about it and yup it was disconnected :-(

Cool! Good to hear that that was it. It's a commonly disconnected item when replacing a battery, even at the deanship level. All you need to do now is clear the codes with a scan tool that is able to clear chassis codes.

Thanks I was able to clear the codes with the Cobb Accessport. Now I just have to wait for my cable to come in so I can register the new battery

sorry to revive this thread Abacus38
but i just changed my battery today and am also seeing the seatbelt tensor warning. Could you provide more detail as to which wire you found that was disconnected by accident? I'm trying to find it as well..
