13.4.4 Fault warning messages
The DTCO 1381 recognizes faults and outputs a corresponding
warning message.
The warning message consists of:
• Entry in the DTCO 1381 data memory
• 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)
If the DTCO 1381 is in the calibration mode, some messages will be
accompanied by an additional pictogram (letter) in the display; see
column "AP".
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.
