6.2 Troubleshooting with displays
Structure of error messages
Meaning of the 3-digit error code
Group error:
A single fault can often cause error messages in
several modules (group error).
Example:
Short circuit at main relay (K1): Error messages
and warnings K1/131, F1/121, H1/631, Z1/631
are generated. It is decisive that the cause is
always a fault, i.e. with number group “0xx“ or
“1xx“. In this case the main relay short circuit
“K1/131“ results in the driving module (A2) not
receiving any load circuit voltage (the main relay
does not react). The driving module then signals
the self-test error “F1/121“.
– If a module supplies various errors, the re-
spective last queued error of the module con-
cerned appears in the display. The error histo-
ry of a module can be called up using the “Dia-
gnosis information“ menu item, directly or at a
later date (with error event depth 6 per modu-
le).
– If fault signals and warning messages from
various modules occur, they are then display-
ed at 4 second intervals in the order they oc-
curred. If the error buffer has been worked
through the errors are displayed again.
Note
Warnings are only displayed once. After that they disappear when the error display is repeated.

The machine can contain several
identical modules however they
control different functions (currently
max. 2 clones).

Error code Description of the error classes
0yz
Hardware error, which requires replacement of the module or a key switch reset.
y=0
y=1 Damaged/distributed supply of processor and drivers.
Peripheral errors, which can be removed using the key switch reset or by the service
technician.
1yz
y=0 Correctable memory error, watchdog error.
y=1 Communications error between modules <-> head CPU.
y=2 Failure of the voltage supply to the load circuit and/or modules.
y=3 Load output short circuited or overloaded.
Drive function
fault F1/022
Scrubbing function
fault C1/133
System function
fault K1/111
Scrubbing function
fault H1/122
y=2 Damaged/distributed power levels (FETs).
y=3 Damaged/distributed module sensors (temperature, U/I measurement).
y=4 Cable interruption for loads or external sensors.
y=5 Wiring error in external sensor <-> signal input.
y=6
Illogical external system status (e.g. accelerator pedal measurement
outside the calibrated limits).
y=7
Illogical system status determined during bus communication from
head CPU (e.g syntactically incorrect bus reply, time exceeded during
telegram transfer).
Cannot be corrected µC memory error.
