The C0265 is a fairly straight forward code pointing to a problem with the Electronic Brake Control Module (EBCM) or the wiring to the Module. The EBCM is located under the vehicle, driver's side, towards the front. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, more commonly here, the EBCM will need to be replaced. Replacing the EBCM isn't all that bad of a job, however, after replacement, it will need to be re-calibrated. This will require the use of a scan-tool that can interact and program. I can provide you with the location and replacement procedure in a PDF file.
