VXDIAG Porsche Tester II Device No Found 99010 99011 Error Solution

Problem:

I was trying to diagnose a Porsche Cayenne 2014 with vxdiag Porsche Piwis 2 system, vx manager cannot detect the device, said “Device Not Found” and PIWIS software failed to communicate with vcx plus.

Error message:

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.

Solution:

Disable/Disconnect local network connection.

Reconnect tester ii and run piwis software again.

Feedback:

Thanks.

It works fine after disable network.
