78 VACC NOT OK
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 more than 1 V
above the minimum value acquired
during the PROGRAM VACC
procedure.
- 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.
79
INCORRECT
START
Incorrect starting sequence.
Possible reasons for this alarm are:
- A travel demand active at key-on.
- Man-presence sensor active at
key on.
- Check wirings.
- Check microswitches for failures.
- Through the TESTER function,
check the state of the inputs is
coherent with microswitches
states.
- If the problem is not solved,
replace the logic board.
80 FORW + BACK
This alarm occurs when both the
travel requests (FW and BW) are
active at the same time.
- Check that travel requests are
not active at the same time.
- Check the FW and BW input
states through the TESTER
function.
- Check the wirings relative to the
FW and BW inputs.
- Check if there are failures in the
microswitches.
- If the problem is not solved,
replace the logic board.
226
VACC OUT OF
RANGE
The CPOT input read by the
microcontroller is not within
the MIN VACC ÷ MAX VACC
range, programmed through the
PROGRAMM VACC function
- 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.
86 PEDAL WIRE KO This is not implemented in ACE3.
- Ask for help to your dealer
technician.
