20F220 code?

Hi all - I did a scan with my JB4 for codes just out of curiosity if anything would come up. I had this code listed below. Car runs fine and no check engine light. I've read it could be a heat management module? Should I take it to the shop; or should I be fine as long as it doesn't throw a check engine light? Also if it is is needing a heat management module replaced; is that usually covered by warranty? I got the platinum 100k mile warranty.

As this falls under drivetrain it should be covered by your warranty.

Good to know! I'll see if a CEL pops up or any other errors before heading in. Don't really want to take it in and tell them "Oh hey; my JB4 was showing a code but car still drives good with no CEL" lol.
