As a customer told, when i connect this piws tester2 with PC and Car, the 4 light on the main unit and usb is blinking slow constantly. If put out the USB connector and then put back in you see all lights light up and then the same again.

On the software, it give me prompt like this:
” 99010: This diagnostic system could not be initialised.
99011: Comm. module not connected. Please check.
Repeat communication setup with [F8].
Press [F12] to start simulation mode.”
