Hello all, just thought I'd share my little learning moment. I was out playing in the snow a bit, came upon a large empty parking lot and figured it's high time I do some 4wd donuts.
I put it in 4-hi, turned off (well, turned off as much as they let you in 4-hi) the ESC and had a little fun. The ESC was (I figure) desperately engaging to avoid me rolling over and/or fishtailing. It seems that after a 5-10 seconds of trying to help it just 'gave up'. The ESC active dummy light remained lit on the dash permanently.
I went back and forth from 2-hi and 4-hi a couple times while also hitting the disengage ESC button a few times and nothing seemed to turn off the dummy light.
It seems that during an extreme enough event, the system decides that stabilty control isn't useful or desired so it turns itself off. I figured, OK...turned the Jeep off, waiting a couple seconds, turned it back on....
Nope, dummy light still on, stability control still off. Scratched my head a little, engaged 4-lo then put it back in 2-hi and viola, dummy light off and ESC fully enabled again. Figured I'd share that for my fellow JK'ers who may not have seen this happen or figured it out yet.
