Internal device
malfunction
and finally
Service!
SrvID:S108
Meaning / Cause
:
The data of the battery-backup memory has been lost.
The possible causes are:
y Failure or malfunction of the internal buffer battery. The
voltage of the battery is inadequate to feed the real-time
clock and the data that is saved in the battery backup RAM.
y In case of malfunction, the data in the battery backup RAM
is deleted.
y If the cause for this malfunction is a weak battery then this
malfunction is displayed if EFAS was previously isolated
from the vehicle battery, otherwise the service ID S105 is
displayed.
Measure
:
y Replace the internal back-up battery.
y Carry out a recalibration.

Internal device
malfunction
Meaning / Cause
:
The possible causes are:
y
Malfunction on the internal communication bus or in the
internal communication module.
y
Internal communication module reports a hardware error.
Measure
:
y
Check for obvious problems, e.g. with the printer.
y
Check if communication on connectors D7 and/or D8 is
malfunctioning.
y
In case of obvious malfunctioning or frequent occurrence
of the error message, the tachograph must be exchanged.

Update the software.
S112 31 40 00 000139 
Internal device
malfunction
Meaning / Cause
:
The ignition signal (connector A3) is showing an unusual number
of status changes per 5 seconds (≥25). Cause of the signal change
could be a potential difference between connectors A5 and A6
(missing or broken wiring) as well as an ignition signal oscillating
between on and off.
Measure
:
Check the wiring on A5 and A6, if necessary connect or replace
the wiring.
Check the wiring on A6, if A6 not wired, then make a connection
to A5.
In case of signal oscillation an extra ignition relay may help to
suppress oscillations.
S113 31 40 00 000139 
Internal device
malfunction
Meaning / Cause
:
The on-board voltage as set by parameter (nominal voltage
12 V or 24 V) does not match the actual voltage measured at
connector A1. The incorrect voltage level was measured over a
period of more than 45 seconds.
Measure
:
y Check the on-board power supply.
y Check the parameter setting for the on-board power supply
voltage and adjust this if necessary.
25 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.
