For a start run a scan on your ECM, this should tell us where the problem is

See this link on how to scan for codes, the instructions are near the bottom

Dont know if your bike has a brakelight-relay . If so this could be bad , check this first ,if rest is Ok ,like you said !.

Get a wire schematic for the BCM and check the brake switch circuit to confirm power , grounds, brake switches input signals and output signal
