Charge air bypass valve circuit open/short to ground

Did the T7 bypass valve mod, left the valve plugged in as stated
T7 Turbo Bypass Valve Mods – TrollTuner
Hyperboost Diverter valve (cleaned today), no vac leaks.. Could the diverter valve itself be bad?

Here is my setup

See if you have continuity across the valve.
