V8-5.3L,What should i check before replacing the ABS module

Bought a tahoe. The abs and parking brake light come on after driving a few miles and stay on. There are no issues with braking just the warning lights lights. Shows error code C0265 Electronic Brake Control Module Motor Relay Circuit. The internet told me the ABS control module is faulty. I removed the ABS module Re-soldered the conections inside and replaced it but this did not solve the lights coming on. Is there anything else i should check or do before buying a new Dorman ABS control module to replace the old one?

My car has an automatic transmission.
