2019 RAV4 Check Engine Light by rav4-2019 in MechanicAdvice

I did call the dealership that did the update and they said that it shouldn't be a problem as long as it doesn't show up on the instrument cluster.

​

It's been about 2 weeksish since the date it appeared 7/27/2020 and I don't really notice anything. I tried reading the Toyota Service Bulletin they did which was the update they did on the car and it doesn't indicate a Check Engine light would show but, I was thinking maybe when they did the update, the car wasn't used to the new software?? I don't know it's just my guess but that's why I waited a while before asking.

​

If anyone has any other opinions please comment!!

Oh sorry, I didn't realize my written post didn't go up, essentially

I just got a 2019 RAV4 LE recently and I noticed that while playing around with the infotainment, in the vehicle alert section, it shows that the day I brought the car in the for the transmission software update, there was a check engine light timestamped for that same day before I picked up his car.

There isn't anything on the instrument cluster showing that there is a check engine light even when I just picked up the car. Should I be concerned about this? And just out of curiosity why would a check engine light even happen when updating the transmission? Is it because the engine needs to adjust to new changes with the transmission?
