An error ‘Open Session Failed’ appears when I attempt to download a tachograph with my digifobpro. How can I resolve this?
The download request has failed. Please 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.
- Ensure that the VU cable is securely connected between the tachograph and digifobpro.
Re-attempt the vehicle download.
