the manual says,
TRACTION LOGIC UNIT: steering potentiometer out of
range.
This alarm signals that the steering potentiometer is out of range. There is a fault in the following
conditions:
- the "Set steer 0 pos" (straight wheels programmation) parameter is wrong (lower than "Set steer min" or
higher than "Set steer max") in the MATCHING MENU.
- the feedback signal of the steering potentiometer is outside the window defined by the "Set steer min"
and the "Set steer max" parameters.
In the first case, repeat the steering potentiometer acquisition. In the second case, check the steering
potentiometer and its wiring again. In case, repeat once again the steering potentiometer acquisition
as a rule, this error ends with me replacing the sensor
