Service abs, traction control, 4wd come on intermittently

[Zaptrac]

Issue started last week, at random times the 3 lights for service abs, traction control, and 4wd all come on at the same time then go out about 30 seconds later. Usually happens when i’m making a left turn but not every time i make a turn. Wondering if anyone has some ideas on what to look into. Before it started i had an issue where my volume would crank to max when i would turn. So i disabled the volume up control on my steering wheel, and this new issue started right after

what i already tried:
1) replaced the clock spring. First i figured that might be the issue because of the volume control problem. I’ve also had a small issue for a while where at random times the lights on my wheel would flicker and it would kick me out of cruise control if it happened. Since replacing the clock spring the volume control issue hasn’t resurfaced yet. But the 3 service lights still occasionally come on.

2) replaced the aux battery. Mine had been disconnected and bypassed for a few years. So i thought i’d rule that out but no fix.

3) i did replace the radio recently so i popped it back out to check all the connections and make sure nothing is pinched and shorting. But didn’t find any issues with any of the wiring harnesses but i guess it is still possible it’s pinching somewhere. The radio does connect into a port to get system readings from the jeep. So i thought it could be causing the service lights through that

If anyone has any other leads to chase that would be great so i can avoid an expensive trip to the shop

Pop out the glove box and check all the connections in the CanBuss system back there. Make sure nothing wiggled loose somehow. That sound like a lot of electrical issues that aren’t necessarily related but have a main focal point. Biggest clue to me is that it happens on a turn. That tells me you have a loose connection somewhere that is breaking contact when the vehicle is oriented a certain way.

Fuse relay check, CanBus check, those points behind the rear seat check. With it being intermittent and not a constant you can try to read codes but it’s unlikely.

Wheel speed sensor/wheel bearing?
Back in the good old days that could cause traction control/abs issues

Next time it happens, switch your display over to see what voltage you have at the cluster. I had a similar issue that threw all the ABS, Traction control, and service stability lights on. My cluster would show 15 to 16V when this happend, but at the battery it was only 12.7. Had a loose battery cable off the positive post ( the closest of the 3 to the firewall) which threw the truck into a tizzy.

That was one of the first things i thought to do. The voltage remained the same, sitting around 13.8-14v anytime it happened
