Sensor data
error
Meaning / Cause
:
The communication via the data channel (pin B4) between the
tachograph and the motion sensor is interrupted. The motion
sensor is not responding or no motion sensor is connected.
Measures
:
y Connect and pair the motion sensor, if not yet done.
y Check the plug connector contacts and lines to the motion
sensor.
y Check the supply voltage of the motion sensor.
y Check the data signal at the pin B4.
y Check the pulse detection of the tachograph via the front
interface.
y Replace the motion sensor.

Security
violation
Meaning / Cause
:
Error with respect to the integrity (authenticity) of the data of
the motion sensor
Measures
:
The motion sensor must be replaced.
S27 15 21 80 00 002452 ! 
Security
violation
Meaning / Cause
:
The motion sensor itself has detected and reported an error while
authenticating and the event is saved in the motion sensor. In
general, this event can occur only if the motion sensor had been
connected to another recording equipment in the meantime.
Measures
:
y
Check the seal on the motion sensor and check the feed
cables.
y
The motion sensor must be replaced if the fault reoccurs.
S28 15 11 80 00 002452 ! 
Security
violation
Meaning / Cause:
An error has been detected by EFAS while authenticating the
motion sensor. The connected motion sensor is defective or
it has not been paired with EFAS or, in the meantime, another
motion sensor was connected to EFAS. Since EFAS repeats the
authentication multiple times when an error occurs, it may take
several minutes for the error to be displayed.
Measures
:
y
Insert the workshop smart-card and carry out the pairing.
y
Check the seal on the motion sensor and check the feed
cables.
y
The motion sensor must be replaced.


Security
violation
Meaning / Cause:
EFAS has detected an unauthorized modification of the motion
sensor.
Measures
:
y Check the seal on the motion sensor and check the feed
cables.
y Repeat the pairing procedure.
y The motion sensor , if necessary the connection line, must
be replaced.
15 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 specification of the
