ABS light coming on and off
For about a month now my ABS "light" and parking brake light have been coming on randomly, everything seems fine, I've just not had the chance to check the truck any ideas on what it could be?

Are you experiancing any parake pedal pulsation at all? The is a TSB on the Corrosion of the ABS sensors on those trucks, but it usually accompanied by a bit of pedal pulsation, kinda like a warped rotor.
Otherwise, the ABS light randomly coming on and off makes me think you have a defective ABS Wheel Speed Sensor that's going bad. They are notorious for failure. They are right on your front hub assemblies. If the ABS light came on and stayed, I'd lean towards the ABS module or pump being defective, but if it's going off then it's not the ABS module unless you have a bad connection on the harness connector going to it. The randomness of the lamp is most likely contributed to an ABS sensor. Easy to replace, but not the cheapest things in the world. Contact me with your VIN and I'll run a GMVIS on it and see if you have an Open TSB or I can get you the aprt numbers to the ABS sensors.

I have no pedal pulsation the ABS and PB lights will just come on and it's starting to be more frequently, I scanned it and no codes where thrown. Is there a way to check the ABS module or speed sensors?
