Internal device
malfunction
Meaning / Cause:
A general internal device malfunction is at hand. EFAS has per-
formed a restart as a consequence of an extraordinary event
during program execution.
Measures:
If this fault continues to occur, the tachograph must be replaced.

SrvID: S98
Meaning / Cause:
The internal real-time clock (RTC) is defective.
The following causes are possible:
y The communication to the clock module is interrupted
y The time is incorrect and cannot be corrected.
Measures:
Correct the time setting in the CALIBRATION operating mode. If
the time cannot be set correctly then the tachograph must be
replaced.

SrvID: S99
Meaning / Cause:
The internal module for controlling the card reader is defective.
The card reader function of both card slots is faulty.
Measures:
If this fault continues to occur, the tachograph must be replaced.

None
S101 09 80 00 002280
!  Sensor
data error
Meaning / Cause:
The input frequency of the real-time signal supplied by the
motion sensor (input B3 to the recording equipment) is not
plausible, i.e. the value is too high (greater or equal than 1.6 kHz).
Measures:
y Measure the frequency at the input B3 and compare it with
the maximum permissible frequency.
y Check the lines to the motion sensor.
y Check the motion sensor and, if required, replace it.
S102 - - - - - - - Meaning / Cause:
This service ID is only processed internally in the tachograph.

SrvID:103
Meaning / Cause:
An error has been detected in the checksum of the program
memory. Apparently, this is a hardware defect in certain memory
locations in the program memory. Correct functioning of the
device is presumably no longer ensured. This fault generally
occurs after the device has been in use for a longer period of
time.
Measures:
If this fault continues to occur, the tachograph must be replaced.

SrvID:S106
Meaning / Cause:
The integrity of the data in the mass memory of EFAS is dis-
turbed. No further data is recorded.
Measure:
The tachograph must be replaced.
24 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 specication of the
SrvID that this event or malfunction has been detected for a short duration.
