The diagnosis is made in 4 points:
1) Diagnosis on start-up that checks: watchdog circuit, current sensor, capacitor
charging, phase's voltages, contactor drives, can-bus interface, if the switch
sequence for operation is correct and if the output of the accelerator unit is
correct.
2) Standby diagnosis in standby that checks: watchdog circuit, phase voltages,
contactor driver, current sensor, can-bus interface.
3) Diagnosis during operation that checks: watchdog circuits, contactor driver,
current sensors, can-bus interface.
4) Continuous diagnosis that check: temperature of the inverter, motor
temperature.
Diagnosis is provided in two ways: the console can be used, which gives a
detailed information about the failure, but the failure code is also sent on the CAN
bus.
