Good afternoon, my ABS warning light and my traction light came on on my dash while I was driving on the expressway 60 mph. Neither of them were in years. At the same time my speedometer went to zero. There was no interruption in the speed I was going. This lasted a couple seconds, then everything went back To normal. When I put my Jeep in park my battery light went on briefly and then went off. I started my Jeep A couple times afterwards. Just to make sure there were no issues. What could cause this?
