Hey guys,
So I'm trying to shut off the abs system in our 2012 wrangler jk, and I've run into some issues.
A little background on the vehicle.. 2012 jeep wrangler, front dana 60 from a ford one ton truck, rear gm 14 bolt from a 2500hd, factory 3.6l pentastar engine and nag1 automatic trans. The vehicle now has full hydrolic steering which causes the steering wheel to constantly rotate slightly. This has broken the clockspring so now the steering angle sensor is malfunctioning as well. We opted out of using selectable lockers in hopes of shutting off the abs system. Last year we managed to limp through by tricking the system into working. Upon purcahsing HP tuners this year, we have begun trying to modify the computer set up to shut abs off completely.
Is it possible to completely shut down the abs?
Last night I threw a tune into the jeep that shut off the three esp control values.. FSO, Trans control and Spark I believe they are. When we we went to drive the jeep this morning, the jeep seemed ok through first second and third gear, but once in third it would not shift anymore. Would not go up or down. I removed this tune and put the factory tune back in it and we were worse off, the jeep wouldn't even shift out of 1st. We completely removed the HP tuners set up from the jeep and tried going back to the super chips set up that we used last year just to limp the jeep by for the weekend and still same issues.
My thoughts are that because of the broken steering angle sensor, combined with the lack of abs.. the jeep just doesnt know when to shift or what to really do. I'm curious if I were to shut off the esp system again, and teach my own shift points through tuning, if that would allow the jeep to shift and drive some what normally again. I'm some what out of ideas here. We only use these vehicles for offroading so abs, esp and traction control are useless to me. Is there any way I can eliminate these systems on this specific vehicle? Either the way I'm thinking it would work, by programming my own shift points, or some other way that maybe you guys know will work that I have yet to find?
Thanks for your help,
