Greetings! After successfully installing new timing chain, no engine diagnostic issues, I cam across this HVAC errors, I have not been able to figure out what could trigger 12 issues at once, did not have this issue pre-timing chain change. Full diagnostics is attache. Any help would be greatly appreciated!

I'm wondering if it is one issue that is triggering all of the other errors. :
I also purchased a new battery and is not coded to the ECM as the battery did not come with a battery code. Trying to figure this out too. Address 08: Auto HVAC (J255) Labels:. 8Tx-820-043-3Z.clb

I have no idea what is causing your HVAC error codes, but changing the battery and not coding it as new battery is not your problem. It just thinks that the old battery is still there and will function just fine until you solve your HVAC problems and then you can code the new battery properly.
