S34 - - 40 00 001177
- - - Meaning / Cause
:
The communication with the instrument panel / E-tachometer
has malfunctioned or is interrupted. The connection between
the instrument panel / E-tachometer and EFAS is monitored by
the tachograph cyclically by means of a life sign message trans-
mitted by the instrument panel / E-tachometer every second.
Measures
:
y First check whether any of the faults listed above (service
ID 32 and 33) are reported and initiate the corresponding
measures listed against them.
y Check the CAN connection to the instrument panel /
E-tachometer.
y Check that the instrument panel / E-tachometer is working
properly.
y Check the specifications of the instrument panel or E-ta-
chometer of the given vehicle type.
y Deactivate the monitoring of the life-sign messages
with the help of parameter configuration (see parameter
RDI=0xF90C). (If other data are displayed correctly on the
instrument panel or on the E-tachometer, then apparently
the handshake message is not supported by this device.
Remarks
:
Depending on the configuration of the CAN fault management
system, the detection of these malfunctions is suppressed for
a maximum of 25 seconds (smaller values are common) after
switching on the ignition. This means that only malfunctions
that continue to persist after this time has elapsed or those that
occur thereafter are reported within a few seconds. Please wait
for the corresponding period of time in order to be sure that
there is no malfunction.

Internal Device
malfunction
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. Proper functioning of the
device is probably no longer ensured. This fault is displayed, in
general, a few minutes after leaving the standby mode, e.g. after
turning on the ignition, when a memory error is detected during
the POST (Power-On Self Tests).
Measures
:
y If this fault continues to occur, the tachograph must be
replaced.

Security
violation
Meaning / Cause
:
EFAS has detected a checksum error in the calibration data after
being turned on. Proper functioning of the device is probably no
longer ensured.
Measures
:
y
Acknowledge the message and turn off the ignition. Wait
until the device turns off and then turn on the ignition
again (alternatively: Send an ECU Reset command with the
sub-function 0x03 (“Soft Reset”) via the diagnostics inter-
face). EFAS must be replaced if this error message appears
again after restarting.
y
Check the calibration data for validity and re-calibrate the
device.
17 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.
