
Vehicle motion
conflict
SrvID: S83
Meaning/Cause
:
EFAS has detected a relevant difference between the speed
values of the paired motion sensor and the speed rvalues of the
GNSS receiver.
According to CR (EU) 2016/799, a speed difference between these
two motion sources is classified as relevant if the median value
of the deviation is continuously above 10 km/h for 5 minutes in
the motion.
Measures
:
y Couple the EFAS with the motion sensor.
y Check cause, why a coupling could not be established (check
plug contacts and supply lines to the position sensor).
y Replace the motion sensor.
S84 22 11 80 00 002452 ! 
Security
violation
Meaning / Cause
:
There are two causes for this error:
y After a few power interruptions, the sensor may not activate
immediately and cause a security violation.
y Pairing with the motion sensor had failed during the initial
commissioning. EFAS remains deactivated (the error is dis-
played after the workshop smart-card is removed).
y The device was activated successfully and new pairing with
another motion sensor by means of a command has failed.
(The error is displayed after the workshop smart-card is
removed as well as after every restart of the device, to warn
that despite the activation there is no valid pairing present.)
Measures
:
y Check the handling instructions of the sensor manufacturer.
y Pair EFAS with the motion sensor.
y Check the cause as to why pairing could not be carried
out (check the connector contacts and feed cables to the
motion sensor).
y Replace the motion sensor.
S85 22 20 80 00 002452 ! 
Security
violation
Meaning / Cause
:
The motion sensor reports an unknown error for EFAS. The
motion sensor used is not compatible with the recording equip-
ment EFAS or the motion sensor is defective.
Measures
:
y
Check whether the motion sensor used may be operated
with the tachograph EFAS.
y
Check the function of the motion sensor.
y
Replace the motion sensor.

Time
conflict
Meaning / Cause
:
A time conflict is displayed if the time between GNSS and RTC
differs by more than 60 seconds.
Measures
:
If this event was triggered, a time correction is triggered auto-
matically, which takes over the GNSS time if the GNSS signal is
valid.
S87 22 31 40 00 000139

Internal device
malfunction
Meaning / Cause
:
The security module of EFAS has detected a possible internal
fault.
Measures
:
If this error occurs several times, the tachograph must be
replaced.

This malfunction matches SrvID S33, however, it relates to the
CAN expansion bus.
22 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
SrvID that this event or malfunction has been detected for a short duration.
