Welcome to the forums.

I'd check the battery and make sure it's up to par, as well as the battery cable connectors and the wiring and eyelet at the starter as sometimes it corrodes and breaks.

Also, sometimes corrosion at one or both of the engine bay grounds can cause numerous error codes which are not necessarily related.

The wires can corrode under the eyelet crimp and insulation where it can't be seen.

The fix is cutting of the old eyelet, stripping the wires to good metal, and adding a new eyelet.

Thank you. I’ll have to check all that. Thanks for providing photos. Going to check the grounds for sure. Only found this video that has similar codes

 

Nice job, and thanks for the update!

 

Did you clean the contacts on the box? Check/clean the wires going into the box?
Use anything to prevent corrosion in the future?

I'd say you got lucky if you caught it before damage was done to the contacts/wires. See several cases where the wires had corroded through and where the relay terminals were no longer usable requiring a replacement box (or wiring an external relay outside the box).

 

I did clean the contacts. Used an electric spray and wire brush and got rid of all visible corrosion. Haven’t checked the wires running into it. But i made a major **** up and might’ve shorted one of the radiator fan’s relay. I was disconnecting and reconnecting my battery a few times as I was trying to find my original issue and accidentally pulled the relay for the fan while battery was connected and caused it to maybe short. Now when i put the new relay in the fan stays on at all times. Which made codes P0539, P0581, P0481 pop up.

- so I either have to replace the fan, or the wires for that relay. That was my own damn fault
