13.4.6 Security breach warning messages
The DTCO 1381 recognizes security breaches and outputs a corre-
sponding 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.
Displayed or printed warnings regarding security breaches are
broken down with an additional code, see chapter 14.5 "Memory
behaviour during events or faults", page 14-30.
