Possible reason(s) for ABS light to come on?
2008, 4.2 with 30k miles. Just had new tires put on a couple weeks ago. Anyway, I've put about 4k miles on my truck in the last month. I just did about a 1000 mile round trip to DC and back. On the ride home last night, the ABS light came on. I pulled over a little while later, and when I restarted the light was off but came back on 20 mins later. Today, I drove about 100 miles before the light came on but it stayed lit the rest of the way. The brakes don't feel any different and the light would come on cruising on the highway, not when braking.
What could be the reason behind the light coming on? Sensor? Any clues would be greatly appreciated.
