Can Predator turn on ESP in a 2009 Jeep Wrangler

[mbehr55]

Can I use the Predator to turn on the ESP in my 09 Jeep Wrangler? Had to do the owner's manual hokey pokey to turn it off when a sensor went out. Dealer fixed the sensor but would not turn on the ESP since I had turned it off. Did the hokey pokey again but no joy. Hoping the Predator can help me out.

Yes, it the traction control disable under quick adjust.

Thank you. I didn't want to unlock it from my 05 Ram until I knew it could be used.

Well, no joy. The indicator light is still on and the display says ESPOFF even though the Predator said I had enabled it successfully. I even installed the 87 perf tune to see if that would help. No joy. No trouble codes either. Anything else I can try with the Predator?

No, sounds like you have an issue in the vehicle, possibly a bad wheel speed sensor, seems to be relatively common.

Just had a sensor replaced at the dealer. Had been forced to do the ESP disable to make the Jeep drivable until the dealer could fix the sensor. ESP is the only thing that did not get reset. I think the dealer couldn't do it either and gave it back as it was.

Now I'm wondering if the only way to fix this is to reflash the computer. Can't I do that with the Predator?

Then let me rephrase the question. How do I do a recalibration with the Predator when it is not prompting me to do one? The Update instructions for the Predator don't cover this situation. I really don't want to take to another dealer....

What did you use to do an ESP disable?

[mbehr55]

The steps outlined in the owners manual. I have repeated those until I am blue in the face with no luck. Last resort is to reflash the computer and I really don't want to pay the dealer for that.

loading a cal update will have no effect on the ESP, thats not in the PCM....

[mbehr55]

So a reflash of the PCM will not reset the ESP to on, which should be the default?

no, ESP is not in the PCM. You'd need a dealer to resync all modules if that is indeed the issue.

I am confident that if you enable it in the tool, and it says it was successful, then there is another issue somewhere...
