Check if there are failures in the microswitches.
If the problem is not solved, replace the logic board.
TORQUE PROFILE (MDI/LED code = 98)
Cause:
There is an error in the choice of the torque profile parameters.
Troubleshooting:
Check in the HARDWARE SETTINGS list the value of those parameters.
VACC NOT OK (MDI/LED code = 78)
Cause:
At key-on and immediately after that, the travel demands have been turned off.
This alarm occurs if the ACCELERATOR reading (in TESTER function) is above
the minimum value acquired during the PROGRAM VACC procedure.
Troubleshooting:
Check the wirings.
Check the mechanical calibration and the functionality of the accelerator
potentiometer.
Acquire the maximum and minimum potentiometer value through the PROGRAM
VACC function.
If the problem is not solved, replace the logic board.
VACC OUT RANGE (MDI/LED code = 85)
Cause:
The CPOT input read by the microcontroller is not within the MIN VACC ÷ MAX
VACC range, programmed through the PROGRAMM VACC function (see
paragraph 9.1).
The acquired values MIN VACC and MAX VACC are inconsistent.
Troubleshooting:
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.
If the problem is not solved, replace the logic board.
VDC LINK OVERV. (MDI/LED code = 77)
Cause
This fault is displayed when the controller detects an overvoltage condition.
Overvoltage threshold depends on the nominal voltage of the controller (see
paragraph 2.4)
As soon as the fault occurs, power bridge and MC are opened. The condition is
triggered using the same HW interrupt used for undervoltage detection, uC
discerns between the two evaluating the voltage present across DC-link
capacitors:
High voltage  Overvoltage condition
Low/normal voltage  Undervoltage condition
Troubleshooting
If the alarm happens during the brake release, check the line contactor contact
and the battery power cable connection.
VDC OFF SHORTED (MDI/LED code = 88)
