I was trying to diagnose a Porsche Cayenne 2014 with vxdiag porsche tester ii system, vx manager cannot detect the device, said “Device Not Found” and PIWIS software failed to communicate with vcx plus.
99010: The diagnostic system could not be initialized.
99011: Comm. module not connected. Please check.
Repeat communication setup with (F8).
Press F12 to start simulation mode.
Disable/Disconnect local network connection.
Reconnect tester ii and run piwis software again.
It works fine after disable network.
