Internal Device
malfunction
Meaning / Cause:
Malfunction of the keyboard has been detected, i.e. at least one
key remains continuously pressed. The tachograph assumes that
a key has been pressed continuously if it remains pressed for
more than two minutes.
Measures:
Check if the keys are being blocked. Devices, in which the keys
are blocked permanently must be replaced.

Display
malfunction
(the text output: “ service
display fault”, appears addi-
tionally on the printer)
Meaning / Cause:
A malfunction of the LCD display has been detected, i.e. the
communication for display has malfunctioned or is permanently
interrupted. There is either no picture on the display (no charac-
ters visible) or it is faulty (ickering, pixel errors, etc.).
Measures:
Devices, in which this fault occurs permanently or in which visible
defects can be seen in the picture displayed, must be replaced.
Remarks:
If the display is too faint then the contrast and brightness must
be adjusted in the corresponding setup menu. In this case,
however, there is no malfunction reported.

S48 31 40 00 003000
Internal Device
malfunction
Meaning / Cause:
Tachograph malfunction, pin B7 (speed signal).
The monitoring circuit of the signal at this output of the recording
equipment has detected a malfunction.
Measures (continued):
Check B7 for short-circuit and measure the signal level. Measure
the pulses at the output B7 and compare them with the input
impulses from the motion sensor at the input B3. The pulse
frequency must be identical, the pulses at the output B7 are
normalized by the taking the value of the k-factor that has been
congured into consideration. Check the connection between
output B7 and the controller connected.
