I have an 02' Silverado and lately the abs is constantly coming on with dry road conditions what in the hell is causing this to happen any help would be appreciated

 

There's a TSB on this problem with GM. Your problem is the ABS sensors in the front wheel hub. Corrosion is building up and pushing the sensor barley out of spec. I fix this problem in ym shop all the time...very common occurance.

 

agreed with above, but once the dealership replaced both of my hub assemblies the problem still occurred. They then told me that it was my Hydraulic Control Unit, and it would not be covered as part of the TSB. So I just removed my abs fuse and never looked back. In most cases doing what Torque said above fixes it.

 

mine does the same thing under 5 mph and its hit or miss. Dealer told me the say way to fix it.. ive done this a few times and it goes away.. but im in a lot of mud and dirt wich is easy to shake it loose they say..

Im going to try this again and hope it fixes it

 

Thanks for all the replies guys im checking it out tomorrow

 

ive got a 04 sierra 2500hd and my brakes ''pulse'' down at like 3-5mph. took my sensors off and cleaned them today. did not to help me at all. still have the same issue!
