Sensor data
error
Meaning / Cause
:
The real-time signal of the motion sensor (pin B3) is interrupted.
The speed display remains at 0 km/h, although the vehicle is
in motion. The motion sensor reports a checksum via the data
channel, which corresponds to a speed > 0 km/h.
Measures
:
y
Check the plug connector contacts and lines to the motion
sensor.
y
Check the supply voltage of the motion sensor.
y
Check the pulses at pin B3.
y
Check the pulse detection of the recording equipment via
the front interface.
y
Replace the motion sensor, the connection line, the tacho-
graph (depending on cause).

Sensor data
error
Meaning / Cause
:
The real-time signal of the motion sensor (pin B3) is faulty. The
speed indicator displays the wrong speed. The number of pulses
counted does not match with the checksum of the motion
sensor transmitted via the data channel.
Measures
:
y
Check the plug connector contacts and lines to the motion
sensor.
y
Check the supply voltage of the motion sensor.
y
Check the pulses at pin B3.
y
Check the pulse detection of the recording equipment via
the front interface.
y
Replace the motion sensor, the connection line, the tacho-
graph (depending on cause).


Sensor data
error
Meaning / Cause
:
The communication via the data channel (pin B4) between EFAS
and the motion sensor has malfunctioned.
Measures
:
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 EFAS via the front interface.
y Replace the motion sensor, the connection line, the tacho-
graph (depending on cause).
