C0550? Help

[jeremymike2]

I dont understand why i am getting this code. My truck is a 2007 GMC classic 4.8L. I would go to a dealership but from what i understand is if my truck is programmed they will void my warranty. Dont need that to happen i guess. If someone could help me out it would be very appreciated. The code is C not P but C0550. Thank you.

That code is an internal check on the EBCM (abs module). Basically if the code is cleared and returns the module needs replacement. There is nothing external to the module that will cause that code.

Where is it at? Is it easy to replace the abs module?

Under the vehicle attatched to the frame on the left side, around the area of the driver door. It's pretty easy to identify, it's the thing with all the brake lines attatched to it. The module is attatched directly to the pump with 4 or 5 torx screws, it's pretty easy.
