Why is my truck doing this

Almost every time I go into reverse my truck throws 2 dash lights. The stabilitrak turns off/on, traction control turns off/on. And I think it’s the symbol/light for 4wd. Where it looks like the frame of the truck with the 4 tires and 2 are turned to the right. No codes and once I back up and park everything goes back to normal. I would post a picture. But I don’t know how. It’s been like this for about 5 months now. With no others issues, lights or codes. Keep in mind my truck is 2wd. Tuning maybe ? Thanks for the help.

So this has never happened prior to it being tuned? Only asking cause you mentioned tuning as a possible culprit.

Ya just after tuning. And the epc fooler I installed with the tuning. I’m just trying to eliminate the options and move onto the other possible culprits. Pretty sure it’s tuning related
