Ok so I was driving down the road and hit a bump and the LOW TRAC light came on for a little, and it usually goes off after about 5 seconds. Well it stayed on, then my BRAKE light came on as well as my TCS OFF light, and my ABS INOP light.... So I pull off at the next street and turn the car off, wait a minute and turn it back on, it was fine after that, but I am wondering what could have caused that???
