SES light, no new codes

[Colinoscopy]

Hey all,

Codes as pictured below.
2EF4 Map thermostat mechanism

I've had this code for the past year but no SES light. SES light new about 1 month prior, I think around the same time I added burble tune (now removed), though can't be sure.

I'm running and checking codes with MHD obviously, is there a way I can check for what's tripping the SES light without having to bring it to the dealer? Thank you!!

Edit: Sorry for the sideways picture orientation, don't know why they're like this. They're oriented correctly prior to upload.

This may be an indication your thermostat is on it's way out.

Any way I can read the code that's causing the SES?
