!  Security
violation
Meaning / Cause:
The integrity (authenticity) of the data on the tachograph card in
card slot 1 is not assured. Errors were found in the data structure.
The following causes are possible:
y A defective card locking mechanism of EFAS (a defect in the
card reader is unlikely with such a fault, since in this case,
other error codes are reported).
y A defective tachograph smart-card.
y An attempt at tampering.
Measures:
y Check the tachograph card in another card slot or in another
device.
y Check the card locking mechanism of EFAS (please take
note of the remarks given under service ID 17 and 18).
y Replace the tachograph smart-card.

Service!
SrvID: S92
Meaning / Cause:
There is a general internal device fault. EFAS has detected an
invalid combination of installed software components. The
application version is incompatible with the software version of
the Security Controller.
Measures:
The tachograph must be replaced.
S93 18 80 00 000800 - - - Meaning / Cause:
The deviation between the GNSS time and the built-in clock is
greater than 20 minutes or greater in absolute terms than 40
minutes since the last calibration.
Measures:
y Insert the workshop card and check the time signal at the
front interface.
y Execute the GNSS test function and check the displayed
time.
y Check the current time of the VU and set it correctly if
necessary.
y After a few minutes, compare both times again. If there is a
deviation, the tachograph must be replaced.

Internal device
malfunction
Meaning / Cause:
A general internal device malfunction is at hand. The device has
performed a restart as a consequence of an extraordinary event
during program execution. The cause here can be, e.g. a defec-
tive memory module.
Measures:
If this fault continues to occur, the tachograph must be replaced.
23 The EFT for this event or the malfunction is not stored to the mass memory in the CALIBRATION operating mode. Information appears in the display with the specication of the
SrvID that this event or malfunction has been detected for a short duration.
