9.3.1 Troubleshooting of master-uC warnings
1) WAITING FOR NODE
Cause:
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.
Troubleshooting:
Check if any other device on the CAN bus is in fault condition.
2) TORQUE PROFILE
Cause:
There is an error in the choice of the torque profile parameters.
Troubleshooting:
Check in the HARDWARE SETTING menu the value of those parameters.
3) STEER SENS KO
Cause:
The voltage read by the microcontroller at the steering-sensor input is not within
the STEER RIGHT VOLT ÷ STEER LEFT VOLT range, programmed through
the STEER ACQUIRING function (see paragraph 8.3).
Troubleshooting:
- Acquire the maximum and minimum values coming from the steering
potentiometer through the STEER ACQUIRING function. If the alarm is still
present, check the mechanical calibration and the functionality of the
potentiometer.
- If the problem is not solved, replace the logic board.
4) DATA ACQUISITION
Cause:
Controller in calibration state.
Troubleshooting:
The alarm ends when the acquisition is done.
