just posting this one up... did this one a few months ago.
ESP (Electronic Stability Program) is the skid and traction control function. In 2wd, you may disable the traction control portion of it, but if the Jeep gets a tad bit sideways, ESP will kick in. This can be highly annoying when you don't need it. In the '07 JKs, you can disable the ESP/Trac/ABS by cutting power to the vehicle's accelerometer.
For '08-up JKs, the ESP can be disabled by doing the steering wheel hokey-pokey. Disabling ESP in this manner disables only the ESP/Traction functions and does NOT affect the ABS. It is not an option for '07 JK owners. There was an update to the TIPM firmware, however this has never enabled the ability to disable the ESP in my JK. Sadly. That being said, I've waited on doing this mod until my rig was out of warranty.
I removed my center console completely. (also a perfect time to run the shop-vac in there
I decided to snip the wire just before the accelerometer. While removing the console, the center section literally snaps off of the console... and makes removal easier. Since I was also looking for a place to put the switch, it was a good idea, because the console has two pieces. If you pick the wrong place, you have to drill through TWO pieces of plastic. I found the bast place just above and behind the parking brake.
The accelerometer is mounted behind the parking brake under the center console.
The wiring harness runs along the top of the transmission tunnel. In the bundle of wires, the one I was looking for is the purple wire with the light blue stripe... which also happens to be on the top right of the plug. All you have to do is snip the wire and install a single pole, single throw switch inline.
Then there is switch placement to consider. I already have a full Daystar lower panel with one unused switch. While it was considered, I decided not to use it. Killing my ESP will be a rare option, so the switch does not need to be up front.
After placing the switch and wires, I reinstalled the console. All went well. Wires were spliced in and the console mounted. The test confirmed that it does cut out all ESP functions. Initially, I wasn't sure how I would feel about the ABS being disabled as well. After full consideration, I think it rounds out the intent of the mod, which is to improve the way my JK will perform OFFROAD
. With the ABS off, I can fully lock my brakes which is really a desired option when wheeling.
With that thought in mind, I realize that the squiggly car, ESP/BAS and ABS lights being lit is distracting, but when you're offroad, most of your attention is directed outside anyway.
