02 Avalanche (ABS)
For some reason the there is a constant buzzing from the Electro-Hydraulic Control Unit (EHCU). My OBD II Scanner pulled two codes: C0265 EBCM relay circuit - open and C0267 Pump motor circuit - open or shorted circuit. Could the EHCU be faulty?

Re: 02 Avalanche (ABS)
Don't forget to check fuse's & relays!
A blown fuse = open circuit
