Default I keep getting a C1646 error code


hi guys
so some of you might know I had a steering rack issue a while back so far I’m not noticing any issues beyond the stuff I’ve posted here.

But it everytime I encounter an issue or read my codes just to make sure everything is running fine I get this. So it’s a recurring C1646.

I want to get ahead of any issues. Advice ?

I used to have it . I tired reseting the DTC or remove the battery and reattach it . If you have self park try to rotate the steering wheel fully to the left and rotate it fully to the right , all while staying in reverse (self park enable procedure after battery removal) . Then the code is gone.

does it make a diff if you actually move the car or do you step on the brakes whilst doing this ? Thanks
