Abs/traction control and now trailer brake. Please help

Hey all, love the forum, should have joined months ago. I’ve had warning lights on for ABS and traction control for a while. I replaced a bad speed sensor to no avail. Changed the ABS control module. Only change now is that there is also a “service trailer brake system” warning in addition to the other two. Anyone have any ideas? Thanks!

Check for loose plugs are lose of power.
What faults are showing when you scan the abs module?
Yes, need to scan the abs.

I would suspect a bad harness plug or a harness chaffed through and shorting a wire.
