The DTCO 1381 detects events and outputs a corresponding
warning message.
The warning message consists of:

• Entry on the inserted tachograph cards
• Warning message on the display of the DTCO 1381
• TCO status output on the CAN bus and on the info interface
• Signal to output D4 (TCO warning output)

The error code can be read-out over the diagnosis interfaces (CAN or
K-Line) with a test device, but it will not be shown on the display of
the DTCO 1381.
