F.B OUT OF
RANGE
This alarm occurs for a fault on the
feedback potentiometer (CPOT on
CNB#6). This alarm occurs if CPOT
exits the range from 0.3 Vdc to 4.7
Vdc.
Check the connections of the
feedback potentiometer. This alarm
occurs when one connection of the
feedback potentiometer is broken.
250 MICRO SLAVE
It occurs when the information on the
status bus between the main uC and
the slave uC is frozen to the 0xFF
value (the slave uC does not update
the status bus configuration).
It is necessary to replace the
controller.
251 KM OPEN
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.
252 KS OPEN
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.
253 KM CLOSED
This alarm occurs at key on if the
slave uC detects the safety contact,
of the main uC, closed prior to be
commanded.
This alarm occurs if the connection
CNA#5 (K1) is around a voltage of 12
Vdc when switching on the key. In
fact, when the safety contacts are
open, K1 is expected being connected
to a battery voltage (not 12 V). Search
for a harness problem or replace the
controller.
254 KS CLOSED
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.
