VSC light with trailer?

Hi all,

I just bought a travel trailer and am having an issue. I have a 2013 TRD OR with the tow package. I got the brake controller (Prodigy P3 brake controller) installed a week ago and its been on with no issues. I just picked up the trailer this morning and didn't have any issues, but leaving the dealer I got on the highway and noticed my VSC light came on. I haven't noticed anything different with the truck or towing but the light is on constant. No codes pulled up on my code reader, I disconnected the battery for 15 mins and still nothing. Could the trailer brakes be causing this?? I disconnected the battery for another 15 minutes and disconnected the trailer harness and it didn't make a difference either. I also tried the directions from this thread and nothing worked.

This thread describes the same issue but no resolution from it.

Any ideas?

 

No one had this issue? I tried re zeroing yaw sensor from one of the other threads and checking for loose connectors. Maybe my alignment is bad and that would cause it? I don't know what would cause this and it figures it would happen right after my warranty expires

 

You have a 13. Get to the dealer. Clearing the code won't clear the light if the the o point has come undone. The may be an issue that can't be seen without live data and or freeze reader data stored. Not what you want to hear but they can unplug things and read data.
And yes the trailer can cause issues. Bring it with you.
