ERRORS
In the event of a fault, attempt reprogramming, then replace INVERTER if
necessary
In the event of a fault, attempt reprogramming, then replace INVERTER if

If this error is indicated, check the electric motor temperature sensor by
allowing the motor to cool to ambient temperature and measuring the
electric motor temperature sensor resistance values as indicated in the
manual
Indicatively, the sensor operates within a range from -5°C and +110°C
(with a tolerance of ± 10°C). The self-diagnosis system identifies an "open
circuit" fault state. (In reality, the system receives no indication of a
temperature increase during use, so the temperature value remains at -4/-
5°C). In the event of short circuit, self-diagnosis is not activated and
instead, a temperature value of 130°C is indicated on the Navigator,
which does not drop even while the motor is effectively cooling. The
system nonetheless cuts out due to motor overheating, the mains charge
indicator lamp lights and the electric motor cuts out. In the event of a
fault, carry out the checks described in the service station manual.
This error is generated if electric motor phase current is higher than +45A or
lower than -45A. Check phases with a multimeter as described in the SSM
