An error 7F3650 shows when I attempt to download a tachograph with my digifobpro. What does this mean?

The error means “The request cannot be performed (VU in a non appropriate mode of operation or internal fault of the VU)”. Perform the following checks:

  • Check that the company card is inserted in the tachograph.
  • Check that the ignition to the vehicle is on.
  • Check that the company card is locked in.

 

Re-attempt the vehicle download.
