Hello
Anyone who have any ide what might be wrong?
When I reach 80km/h apprx. 50mph the "Check Antilock" lamp light up. It does not go off again unless I turn off the ignition, then it is ok until I reach 80Km/h again.....

It sounds like you could have a speed sensor going bad, it should be throwing a code in the pcm, have a shop check out what codes you have and go from there

 

x2 what livegreenxj said.. You can go to a parts store like Autozone or Advanced Auto Parts and they can hook and ODBII scanner up to it and get codes and you can also do it yourself and the method depends on what year your XJ is. So post your model year and I can tell you which method to use to get your own codes..

 

It is a -91 Cherokee 4.0

Pull the exact code and we have a list in a sticky you can refer to. OKC has a FSM and can help talk you through the repairs.
