Autowbrake not working

  No personal experience but I read the installation manual. To begin with, your 2018 T@b came with a 7 pin plug from the factory so if it has a 4 pin somebody messed with it. The 4 pin does only have running lights and left/right turn and brake light. The autowbrake senses when the brake lights come on and becomes active. It does need 12V power to operate the electric trailer brakes, and according to the manual that power comes from the trailer lights circuit (for a 4 pin configuration). So the tow vehicle needs to have the lights turned on.

  @Explorer2 - I think you mean a 7 pin, but, besides all that, we had a Prodigy RF brake controller that died after 7 years.  These things do fail.  Ours did the same thing - brake lights worked, but the brake controller would not engage.  Replaced it with a plug-n-play Prodigy P3  proportional controller.  We learned that if you have a non-standard controller, it is difficult to replace on the road if you are somewhere more remote.  You can get a standard controller anywhere.

  @Grumpy_G that's correct, you have to have the headlights fully on, not just running lights, to power up the Autowbrake. I only used it for one trip but I found it to be very adequate.
