ABS Codes

[TonyThompson229]

I have a 2002 GMC Sierra 1500 4x4 5.3L extended cab. With no pattern, it throws the ABS light and the “brake” light simultaneously. Hooked up my scanner and it gave me these while the truck is running:

C0241: Electronic Brake Control Module Control Valve Circuit Malfunction

 

C0242: Engine Control Module Indicated Traction Control Malfunction

C0245: Internal fault in the EBCM

 

C0246: Electronic Brake Control Module Control Valve Circuit Malfunction

 

C0251: Electronic Brake Control Module Control Valve Circuit Malfunction

 

C0252: Electronic Brake Control Module Control Valve Circuit Malfunction

 

C0265: fault code indicates that the Electronic Brake Control Module motor relay circuit has failed due to a performance issue.

 

When plugged up and the truck is off, the scanner gives me a C0265 code. 
Ive googled it but was curious if anyone else has had all of these issues at the same time before, and what it took to fix them.

Code definitions would be helpful, there are over 18000 codes, no one has them memorized
