This alarm occurs if the slave uC detects the safety contact, of the
main uC, open when expected being closed.
It is necessary to replace the controller.
CAN Bus Code = 254
This alarm occurs if the main uC detects the safety contact, of the
slave uC, closed prior to be commanded.
This alarm occurs if the connection CNA#4 (NK1) is around a
voltage of 12 Vdc when switching on the key. In fact, when the
safety contacts are open, NK1 is expected being connected to a
minus battery voltage (not 12 V). Search for a harness problem or
replace the controller.
CAN Bus Code = 252
This alarm occurs if the main uC detects the safety contact, of the
slave uC, open when expected being closed.
It is necessary to replace the controller.
CAN Bus Code = 218
The main uC sends an analog signal towards the slave uC to reset
the slave uC on demand. When the slave uC detects this analog
signal external to a window from 2.2 to 2.8 and not in the range to
generate the reset on demand, the slave uC raises this alarm.
It is necessary to replace the controller.
CAN Bus Code = 70
This alarm occurs if the circuit to limit via hardware the current in
the motor is either always active at key-on or repeatedly active
when the motor is turning.
Check the motor is suited to work with the eps-ac0 (not oversized).
Otherwise it is necessary to replace the controller.
CAN Bus Code = 73
This alarm occurs when the current in the phase W of the motor is
zero and the motor is commanded for moving.
Check the power fuse is OK. Check the battery positive arrives to
the controller. Check the continuity of the wire in the phase W of
the motor. Otherwise it is necessary to replace the controller.
CAN Bus Code = 72
This alarm occurs when the current in the phase U of the motor is
zero and the motor is commanded for moving.
Check the power fuse is OK. Check the battery positive arrives to
the controller. Check the continuity of the wire in the phase U of
the motor. Otherwise it is necessary to replace the controller.
