abs traction control service 4x4 light on

[joshysock]

So I'm new to this forum, just wanted to express how annoying this issue is, traction control, abs and service 4x4 light on, I live in Ohio and its winter time and I cant use my 4x4 or cruise control, I changed the rear abs speed sensor and connector didn't solve anything, checked volts in both I had 12 volts but no ground so I had the truck on the lift inspecting the wire harness and ended up losing power to the abs connector, so clearly its an electrical issue not sure why there isn't a recall on this issue, now I'm debating on getting rid of the truck and or trying to fix it, I've always fixed my own trucks, thought about calling a dealer for a quote.

I have the same issue on my 2019 2500. It used to happen only once in a while and now it's every time it rains. lI get warning lights for ABS, traction control, Front Collision, Trailer Brake and no 4wd. I dont have a solution yet but i'm working on it and feel your pain.

I was told the control module went out. Im still waiting on the part for my 2018.

yeah i've also read online that some guys have had the ABS Module replaced and it fixed the issue. I'm going to load up the parts cannon and fire a new module at it. i'll let you know if it fixes the issue,

You should at least check and see what specific code is causing those warning lights to come on. There are several different reasons the warning lights can be triggered and while checking the code doesn't tell you exactly what the problem is or what part needs replaced, it can least narrow down where the issue is coming from.

Faulty brake switch can do it too. Happened on mine. Maybe your initial problem WAS the wheel sensor, but this time it's the brake switch. They weigh about 20 grams so it's no wonder they commonly fail. It's a super-easy DIY replacement. Have someone do a scan and see what comes up. Or watch the pedal switch real-time within the scan tool as you press the pedal many times to see if you get a bad signal (not closing the circuit) on a push. Autozone or OReilly's can scan for free, or anyone with a snap-on scanner can read that. Or just replace the switch. I think they're like $30 from Amazon and a 10 min install. Hopefully that's your problem.

Good luck. Hope it helps.

Edit: 2012 is a GREAT year btw. Lot less electrical gremlins... No EPS.

What specific codes are stored in the ECM?

 

[Hm710]

I can't remember if I tried to hook up my old obd and there wasn't a spot or I got no codes. I'll look when I'm home next.
Also looking for the proper front fascia wiring harness and replacing the park assist sensors. Guessing they are related issues...

No its not. its literally the worse year . POS 6 speed , POS Lifters in engine, 1st year for those POS gen 4 front diffs. Every cool upgrade is 2013+ when you're looking to buy something.

I love my 2012 and that because I literally almost have nothing left that was original...
