VDO and secondary CAN-Bus enabling

Some VDO Tachograph may be con gured with the Secondary CAN-Bus
disabled by default. In this case the function will need to be enabled with a CTC
II programmer with 2.6 rmware or later or Stoneridge Optimo.
If the CAN LED (GREEN) does not illuminate on the digiDL-B / BT and the
Tachograph has a Secondary CAN-Bus this is the likely cause.
The VDO programmer settings as we know them are; Programming – TCO
Parameters – CANBus – Remote Download (ON) and TCO Parameters – CANBus
– CAN2 (ON) . This work although not classed as a full calibration will need to
be done with a Workshop card installed.

CAN-Bus Baud rates

From 2012 onwards Mercedes upped the Baud Rate of their CAN-Bus and in
turn the Tachograph's Secondary CAN. The digiDL-B / BT rmware was
updated in version 1.18s to cope with this change. The digiDL-B/BT now
automatically detects and adjusts to work with both 250kps and 500kps CAN-
Bus baud rates. You are advised to upgrade earlier versions of the rmware

Rear security seal

In circumstances where a rear security seal is tted to the Tachograph,
normally where the speed is being taken from the Tachograph, this must be
re tted and resealed. Resealing can only be performed by a calibration
station. The seal is not required by law in the UK if the speed is being taken
from a separate source. UK aftermarket Tachograph are supplied by default
without a seal. A secondary seal box can be used if the installer wishes to use
the Tachosys plug and play cable and make tamperproof the A connection.
Our current understanding is that a seal must always be tted in Denmark
and Spain.
