This message means that the tachograph answers the RDU on the CAN line, but refuses the remote download. The RDU Manager shows it with the code MSG019 (MSG015 in older versions). The Multi Company Manager also lists it as "Remote download not enabled" in the Problems tab. The LED of the unit blinks 8 times, see the blinking table.

If the tachograph does not answer at all, you get a different message: No response received from CAN, vehicle not under ignition.

1. Take out any card from the tachograph

The tachograph refuses the remote download while a company, workshop or control card is inserted in it. Take the card out and wait for the next download.

2. Check whether the tachograph can be downloaded remotely

Right-click the vehicle in the RDU Manager and choose Check remote download. It tells you whether this tachograph can be downloaded remotely, or only through its front interface.

3. Have a workshop switch on remote download

You cannot do this yourself. A workshop must switch on the CAN of the C connector and remote download on it, with its programming tool and a workshop card:

  • VDO DTCO: CAN 2 on, remote download on CAN 2 enabled (for example with a CTC II or MKII programming tool).
  • Stoneridge SE5000: Remote Download C CAN configuration = Enable and Remote Download A CAN configuration = Disable. For downloads with the ignition off, also set Wake-up on CAN and CAN Answer Request to Both.
  • Intellic EFAS: menu Installation > Remote data download = On.

After a tachograph is replaced, the new one needs these settings again.

4. Old tachographs and the front interface

Old tachographs have no remote download on the C connector, for example a Stoneridge SE5000 with software older than 7.2. A workshop can tell from the part number and the software version on the technical data printout.

If the RDU is connected to the front interface of a VDO tachograph through a K-Line converter, the front interface must first be unlocked with a DTCO Update Card Front Interface.

Contact support

If the message stays, open a ticket and send:

  • the terminal ID,
  • the tachograph make, model and software version (technical data printout),
  • what the workshop has set in the tachograph.
