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!

Went to start my 2014 with the original batteries with morning (in heated garage). Got the service ABS, traction control, then the trailer brake followed by service throttle. Shut it off and checked the codes, low system voltage and loss of CAN BUS. Put 2 new batteries in it and all is well. Either your batteries are taking a dump, or you are losing communication with CAN BUS.
