2007 GMC Sierra 3500HD LBZ with codes U1041 and P0504

Question

I have a u1041 and p0504 code and my abs light and brake light are. Continuous dinging sound every time the brakes are pressed. I have replaced the brake switch and the (EBCM) electronic brake control module. I have tested continuity through the wiring from the EBCM up the fuse panel, also up to each ABS sensor harness, there are no breaks in the wiring. Any suggestions where else to look
