You used Ktuner tune and your ECU number is 5an-32?

Me and other guy in my country had the same issue. Do you have start-stop? if yes, does it work after the flash? if not than you need to disable the U129e error in "disables' and reflash again a new tune.

Not sure what start-stop is but I will definitely disable the code thank you.

Nope I could never get rid of it no matter what I did.

Not all ECU software versions support disabling that code. If supported, it is listed in the "disables" section of the software.

Mine didn’t support it and the light pissed me off so I put back to stock and sold the tuner.

Seems like KTuner would gladly add the option for you if it was deemed necessary for your vehicle. Too late now I guess.

Can this code pop up from uploading a tune? I got in a wreck and when getting it fixed the dealership notified me of the code. I'm trying to figure could this code be detrimental to the car?
BTW the wreck was a fender bender sort of accident so nothing with the front end idk if that would matter
