I finally find a bumper I can live with. Has everything I want on it: factory fog holes, winch hoop, light tabs etc. Anyhow, I get home tonight, pull the OEM bumper and put the new one on. The new bumper is about 60 lbs maybe. The only electrical thing I did was unplug the fogs, put them on the new bumper and plug them back in. I get in to drive a bit (you know to dirty it up some) and the ABS and ESP BAS light comes on along with the other ESP, the little skid marks light and stays on. I disconnected the battery for thirty seconds, no dif. Steering wheel's centered, I didn't touch any other system. I've got a Daystar 1.75 lift that's been there for months.
Any ideas? I'm loving this Jeep, but right now I'm not sure about the computers.

 

maybe you pinch the wires to the fog lamps when you reassembled the new bumper causing a short.I would check the wires.

 

I would double check your steering, with the weight of the new bumper and going around turns it might be throwing it off just the slightest.

 

Disconnect the battery, then turn on the key for 30 seconds. Turn off the key, recon battery.

The JK headlamps are controlled by the TIPM and the thing won't activate them with the battery disconnected. Without any electrical load it could take some time longer than 30 seconds to reset the computer.

 

Mine comes on a couple of times a month for no apparent reason...... *sigh*

I think it's that HAL 9000 computer they put in it.

Ditto on the *sigh*

BTW does it stay on long?

 

It usually seems to reset after a few hours of being parked. I don't disconnect the battery or the computer or anything.

Also, it seems to be more frequent the hotter the outside temperature is.... which is just an observation, not necessarily a true statement.

 

Can anyone shed any light on this? My Warn front bumper is taking up space in my office (the wife doesn't know about it yet) hoping to be installed this weekend but I dont want any esp problems. I ve been lucky so far with lift wheels and tires and no real issues.

 

I'll take your winch off your hands so you don't have to worry about it... But honestly, I don't think anyone really knows....

 

I wouldn't worry too much. It's probably something stupid I did. I'm a little under the weather today, but I'm going to definitely look into it tomorrow after work. I'll post the what-not when I figure it out. I would like to hear what you think about the Warn (my second choice) after you've had it on for a bit.
