I'm trying to use the EPB service function to change the rear brake pads on my V70.  The MD802 unit will connect to the car's EPB module, but then I encounter the following issues:

1.  Live data is a bit erratic, with the various fields randomly changing between real values and N/A.
2.  The apply brake, release brake and service mode features do not work and only return the error message: "The selected function is not supported at the moment".

The EPB software was recently updated and shows v2.01 for Volvo.

Any help to get this working would be much appreciated.  Thanks.
