Well after 25 years of Heavy Line mechanics I thought I was a decent mechanic but I'm running out of ideas. 2012 JK 4-door Wrangler w/64,000 miles. My wife bought this new and said no rock climbing but now that's all we do. Fell in love with MOAB, So I installed Rock Slide Engineering Sliders, AEV 3.5" lift kit, 35" BFG Mudders on Method Bead Locks, new Dynatrack Pro Rock 44 front Diff complete, and welding on a truss & I re-geared the factory rear Dana 44 with ARB locker, chromemoly axles and 4:88's. Used the AEV proCal module to recalibrate the trans/shifting and had no problems for 200 miles. Drove awesome, nice and quiet with lots of power and NOW, Sway Control Light is on, as well as check engine light and ABS light. Disconnected the battery for a week (been busy) cycled key and light switch on and off, vice gripped the terminals together and stood on 1 foot. Did everything I read in numerous forums to clear memory; adaptive and long term. Do any JEEP professionals have any ideas? No scanner yet. Howdy

Can you swing by an AutoZone or Advance Auto and use one of their scanners?

Not to be banal, but are you 100% sure the terminals are fully seated on the battery? Clean terminals? My negative terminal was a little loose and made my dash lights spontaneously go haywire.

This may be redundant but is steering wheel straight?

I'm kinda thinking you might have a bad speed sensor makes the most sense.

^ wheel speed sensors can also cause a whole lotta lights. They also break. A lot. I've gone through at least 10 wheel speed sensors since I really started wheeling my rig 2 years ago. Luckily the AutoZone brand sensors are a few inches longer than stock, hehe
