Description
"The controller receives from the CAN the message that
another controller in the net is in fault condition; as a
consequence the controller itself cannot enter an
operative status, but has to WAIT for the other controller
coming out from the fault status.Troubleshooting: check
the CAN network connection and verify the CAN
communication of the other modules connected to the
CAN network."
This alarm occurs only when option ENCODER
CONTROL is off. Then, if the encoder is frozen and the
steering motor is demanded for moving at higher than
40% of the maximum motor speed, this alarm occurs.
Check the encoder is right working. This alarm may be
masked (for the trouble shooting activity only) by setting
special adjustment DEBUG OUTPUT to level 11 and
recycling the key . Then it is possible to verify the reading
ENC SPEED is frozen or not meanwhile the steering
motor is turning.
Cause :
This alarm occurs when there is a short circuit of one of
the coils connected to outputs of the Combiac1 (LC coil
or EB coil). After the overload condition has been
removed, the alarm exits automatically by releasing and
then enabling a travel demand.
Troubleshooting :
A)
The typical root cause for this error code to be
displayed is in the harness or in the load coil. So the
very first check to carry out concerns connections
between controller outputs and loads.
B)
In case no failures/problems have been found
externally, the problem is in the controller, which has
to be replaced.
Cause :
At start-up the watch dog signal is already active before
the software has generated it. At standby or running
condition the watch dog signal is not active (in alarm
status).
Troubleshooting :
The WD hardware circuit or microcontroller output port
are damaged. In both cases no external component are
involved. Replace the logic board.
