ERROR MESSAGE RP1210_READMESSAGE ERR_INVALID_CLIENT_ID Check your adapter 129 A. PF- Diagnose needs to be told where to find your adapter, this is done by the driver settings for your device. If you selected a driver that is incorrect or if you selected a COM port for a serial type adapter and the com port is incorrect, or if the vehicle key is not in the RUN position and finally if there is a problem with your datalink, this error will occur.
