I have checked all wiring and can not seem to find out what is causing it. I also went and replaced the pigtail as well. has anyone figured out what is causeing the trl abs light to come on when bobtailing.

Still have the issue here, bob tail too. Had it in a good trailer shop, he said it was my tractor. Funny thing, when I pull one of our Canadian trailers, I forget the manufacturer, no light, ever. When I pull an Extra Lease Great Dane, the ABS light is intermittent. I have no clue and just live with it. Does not seem to be a fix. And yes, I have had the pigtail tested a few times at different shops and International run their Diamond Logic, nothing. Pigtail test always comes back good and is not that old, and I keep the plug greased. It is a straight pigtail, if that matters, not one of the coiled ones and is ran in parallel with my rubber hosed airlines with that plastic wrap piece holding them all together. There is plenty of slack... New spring holder on back of cab too. No clue what is going on... No codes in the truck or with the ABS Controller...
