How to Reset the ECU on a Jeep Wrangler JK

[Joelkay]

I had to Do it 2 times and the 2nd time I did it I went slower with the pedal then the first time. Are you getting the lightening bolt and then limp mode? If so all you have to do is turn the key off then back on and it will reset then be good and you can go on with your plans.

It was after the 2nd reset that it finally fixed it and that was about 1.5 years ago.

What did you do with the pedal? My lights are exactly this. But the above instructions don’t mention a pedal step.
