RE: abs and parking light comes on at 60mph
I used to have this problem, my problem was that the brake light switch was not working properly. the brake light switch is located upwards the brake pedal, sometimes your brake lights are continuously on when you have this problem -meaning that the switch is not adjusted properly.
if your switch is just misadjusted try pushing your brake pedal down while pulling the plunger out of the switch then release your pedal back. Also the switch is not expensive to replace.
I hope this is just it, hope this helps a bit.
Edit: also your if your problem is the brake light switch then your cruise control sometimes does not work....
