ABS and E-Brake Lights

[Red_Raider]

Ok so last night I was driving around town doing some errands. After one of my stops, I proceeded to the next one, but my ABS and E-Brake lights came on! I checked the parking brake just to make sure it wasn't engaged and it wasn't. I made another spot and the lights went off this time. I'm not sure what could be causing this problem. Any ideas?

Dirty sensor or bad sensor. If its not a problem then pop out the light jk but yea check the sensors

Ok so I went to Auto Zone this afternoon. They pulled a P0032 code. It has nothing to do with the abs or parking brake. Instead it is a knock sensor. Anyone help me with that?

That does not make any sense. Why would the brake and abs light come on with a knock sensor. I have the same problem. As stupid as it may sound, it was raining when I did it but I drove about 40mph and slammed on my brakes (in an empty parking lot) and the wheels locked up on me. Its the abs module located between the driver seat and the passanger under the truck. Known GM problem. Some say just to take out the ground and clean it from rust and re ground it, but I did it and its still there. ABS does NOT work!!

Well Unless your CEL light is burnt out that could be the case as for the ABS issue are your brakes acting funny?
check your hubs sometimes a bad hub will trigger a ABS issue

Check front wheel speed sensor! The abs and wheel speed sensors on our gmt800s are known to have issues.

Will do I have to look at my knock sensor too while I am at it. I guess a "great" weekend project I have for myself

Hey at least you can go to the auto craft shop. Since I ETSed I have my driveway.

I hear the speed sensor should just be cleaned and reused but I cant figure out why people dont just buy a new dorman sensor.I wonder if the dorman sensor has the same issues as the sensors on our trucks.My sensors have been cleaned a few times already and my truck only has 65,000miles.
