How to Solve PIWS2 99010 and 99011 errors

Recommended Posts

When I connect this Piwis-Tester II to PC and car, the 4 lights on the main unit and USB keep flashing slowly. If you unplug the USB and then plug it back in, you’ll see all the lights come on and then the same thing again. The software gives me the following prompt:
” 99010: This diagnostic system could not be initalised.
99011: Comm. module not connected. Please check.
Repeat communication setup with [F8].
Press [F12] to start simulation mode.”


Two step to solved it:
1. uninstaled the driver of piwis tester ii, if customer can not sure which is piwis tester ii driver, just check the device manager like pic.2 when you connect the piwis tester ii to laptop
2. re-plug piwis tester ii usb cable into laptop, the new driver will be installed automaticly.

Then the 99011 Error Comm. module not connected will disappear. Customer can start your work on cayenne 3.2 9PA from 2005 year.

Customer may asked, what’s the problem exactly?
From the attachment showing, we can see, customer connect the usb cable to laptop, even the bottom usb indicator light of the piwis tester ii do not light up, so it’s must be the piwis tester ii disconnect to laptop.

Then check the secound picture, we can see that the piwis tester ii usb driver is not configuration correctly, so the error come out in third picture. Now we can confirmed the problem caused by piwis tester ii usb driver not installed property.
