Traction Control light Only under load. One tons.

I did some major mods to my 2014 JK.

I swapped a 2006+ dana 60 and a 2012+ Sterling into my 2014 manual JK.

And a bunch of other mods. that I don't think are relevant.
added hydro-assist
rear gas tank location
atlas 4spd


I am having just my traction control light activate only when under load. Specifically when I have a sustained acceleration. then braking and slowing down occurs unless I let off the gas. TC turns off and I can accelerate again. and again the TC comes back. its enough that I can't really drive past 35mph.

No check engine light. However when scanning I get a C2100 - Battery Voltage Low. which seems pretty generic as a chassis related problem. (bad ground I assume).

The steering wheel has been centered (and re-centered) using my AEV procal
My axles are centered to the vehicle.
Although my speedometer is working I am in the process of replacing both rear wheel sensors (they arrive tomorrow).


I feel I have blinders on and can't see all the possible problems. Any thoughts on this that I'm not seeing?

First thing that comes to mind is a faulty sensor. The second thing is you may have fucked up your clockspring sometime during your build. Unless you strapped your steering wheel in place and are sure it didn't move when you did things like install hydro assist or an axle swap then its a sensor most likely. If you left your steering wheel flopping in the wind when you did these upgrades ill bet on the clockspring

Thanks. I did strap my steering wheel down. Even if I hadn't and it was the problem, I would excet to have the TC activate constantly. I'm working on rear sensor replacement. I'll find out shortly. Another thing that come to mind, my fuses pass visual inspection, I may test them.

Just kinda spitballing here but how significant of a torque reaction do you have on throttle? Not sure if that is the correct wording but does your Jeep lift the front DS corner more than than PS? If so perhaps that coupled with a drag link/track bar mismatch has your ESP thinking you’re in a yaw situation. Also my experience with low voltage, fix that first. Some of the most bizarre seemingly unrelated symptoms are caused by low voltage.

try the wheel sensors. also try to borrow a good diagnostic scanner than can read the wheel speed for each tire in real time. I was having problems after my 1 ton swap so I put it on jackstands and watched the wheel speed as I spun each wheel. I discovered that a new sensor was bad so I put the stock JK sensor back in and it works.

Thanks Elusive. that advice is spot on. 2011+ sterling have 55 tooth rings. I'll be swapping to 60 tooth.
