224 WAITING FOR NODE
"The controller receives from the
CAN bus the message that another
controller in the net is in fault
condition; as a consequence the
controller itself cannot enter into an
operative status, but it has to wait
until the other node
comes out from the fault status."
Check if any other device on the
CAN bus is in fault condition.
226 VACC OUT RANGE
"1- The CPOT input read by
the microcontroller is not within
the MIN VACC ÷ MAX VACC
range, programmed through the
PROGRAMM VACC function .
2- The acquired values MIN VACC
and MAX VACC are inconsistent."
"1- Acquire the maximum and
minimum potentiometer values
through the
PROGRAM VACC function. If the
alarm is still present, check the
mechanical calibration and the
functionality of the accelerator
potentiometer.
2- If the problem is not solved,
replace the logic board."
227 HW FAULT
At start-up, some hardware circuit
intended to enable and disable
the power bridge or the LC driver
(output A12) is found to be faulty.
The hexadecimal value “XX”
facilitates EP technicians debugging
the problem.
This type of fault is related to
internal components. Replace the
logic board.
228 TILLER OPEN
Tiller/seat input has been inactive
for more than 120 seconds.
"1- Activate the tiller/seat input.
2- Check the tiller/seat input state
through the TESTER function.
3- Check the wirings.
4- Check if there are failures in
the microswitches.
5- If the problem is not solved,
replace the logic board."
229 HW FAULT EB.
At start-up, the hardware circuit
dedicated to enable and disable
the EB driver (output A4) is found
to be faulty. The hexadecimal value
“XX” facilitates EP technicians
debugging the problem.
"This type of fault is not related to
external components. Replace the
logic
board."
230 LC COIL OPEN
This fault appears when no load
is connected between the NMC
output A12 and the positive voltage
(for example the KEY voltage).
"1- Check the wiring, in order to
verify if LC coil is connected to the
right
connector pin and if it is not
interrupted.
2- If the alarm is still present, than
the problem is inside the logic
board;
replace it."
