Hi everyone, looking for some help.

I was driving home tonight and suddenly the high beams turned on. On one hand it was really cool because I could turn on the fogs too. On the other I was blinding the heck out of people.

Any recommendations on how to diagnose this problem?

2009 jku with 2nd generation Truck Lites, connected with the Susquahanna harness. I've had them for a long time with no problems.

The lights shut off when the Jeep is shut off, and when the headlights are switched off.

Thanks

 

Those things are controlled by the TIPM. And it's a lot more sophisticated than the old school fuse boxes. If you still have the capability of temporarily going back to the OE headlights, I would plug them in and then do a reset on the TIPM.

Good luck brother.

 

Try pulling the neg battery cable for 15 minutes.

Thanks. I will try these in the morning and see how it goes.

 

x2 on pulling the positive off the battery.

 

The battery pull worked. Everything is properly again. Weird it can just happen like that.

Thanks for your help. This forum is fantastic.
