Pro trailer back up assist

[Boen]

When I push the button for pro trailer back up assist ,screen pops up and ask if the trailer is hooked up or not, and when I choose, yes it comes up with the list of my trailers and every time I select one nothing registers or goes any further, I even tried adding a trailer which it let me, but it doesn’t go any further

Did you perform the alignment procedure. Is the target sticker installed on the trailer?

 

[Boen]

Can’t get any further than that screen that I posted

Might be a silly question but is the trailer actually plugged in.

 

[Boen]

Yes, I tried pugging it in many times. The dash shows trailer hooked up

I have the same problem... an OTA messed up something in my configuration. Still haven't figured out exactly what.

Do you have the trailer brake controller? Does squeezing it or pushing the gain buttons do anything?

 

[scott griffitts]

Ok. If I’m not mistaken you need to calibrate the trailer. And, to do so be sure the calibration sticker is in place then go to a large parking lot and try it then. I found it won’t go further if it’s just in the driveway.
I hope this helps
Also, I had to put in the hitch, sticker dimensions before I drove the parking lot to calibrate. I just had the dealer update my Sync4 to the latest revision a couple of weeks ago (24127)
so, it deleted my save trailer info. I appears that now instead of re-entering those dimensions it tells me to drive it to calibrate. That I haven’t done yet

Then you are in better shape then I am... Had it all working including Hitch Assist (truck backs to trailer for you) then lost it with an OTA. Here is more info in the link. I am sure we will get to a solution one day...

When I hit the trailer back up button the screen pops up and ask if trailer is hooked up , If I say no it will do the Pro trailler hook up assist but if I hit yes the screen shows list of trailers but I hit any of them it dosnt go anywhere, The screen acts like it responds to the comand but dosnt go anywhere?

I worked through it in private messages with @Boen Andy. The solution was:
Change TSF & TSC:
APIM: 7D0-01-03 xxxx xx*x xx-- change 3 to F and
1. Reboot APIM;
2. Clear and rescan DTCs.
