Scanner Code U2100 ABS

I am getting a scanner code of "U2100 ABS" and no other codes. Does this suggest that the ABS is not functioning or something else? I suspect that the front wheel bearings are on their last legs - especially the right front

U2100 Controller Area Network (CAN) Bus Communication- BCM, EBCM, ECM, IPC, PCM, PSCM, Radio, SDM, TCM, VCIM

U2100 is a general loss of comunication between the ECBM and other CPU's, could be the fuse, corroded connector or worst an ECBM failure.
