You can by pass the EWS. I did it on mine when it had a F11 amp draw. It took a reprogrammed DME and EWS module removal. Worked fine. After fixing the GMIII module and another amp draw, I reversed it by installing the original DME and EWS module. The two big wires at the EWS module are connected together with a fuse. DME removal and installation is easy.
