So yesterday afternoon my ABS and parking brake light came on and stayed on, parked the truck for an hour or two and it still came back on. Hopped in this morning to leave for work and no light. Coming home from work I just noticed its on again. Fluid is full, and brakes feel exactly the same. Anyone know what causes this commonly? I get my superchips tomorow so I can pull the codes and see what they say.

 

forgot to mention cruise control went out as well

 

rear wheel speed sensor.

 

Sounds like a stop/brake light switch if the cruise is inop.
