Units:
Boolean
Description: True
The MCU has detected an IGBT switch failure.
False
The MCU has not detected any IGBT switch failures.
When an IGBT switch fails, the MCU can no longer safely operate.

MCU Bad Position Signal

msb:
13
Offset:
0
Scale Factor: 1
Min Value:
0
Max Value:
1
Units:
Boolean
Description: True
The MCU has detected an error in the leg current sensor.
False
The MCU has not detected any errors in the leg current sensor.
This situation may be transitory or persistent. If this situation is persistent, the MCU is unable to
determine the motor’s position and will cease producing torque. When this occurs, the TCU will
shift to Neutral and cease supplying torque to the vehicle.
7.3.2.35
MCU Phase Current Sensor Error
dbc ref:
TCUStat2_MCUPhaseCurrentSensorError
lsb:
12
msb:
12
Offset:
0
Scale Factor: 1
Min Value:
0
Max Value:
1
Units:
Boolean
Description: True
The MCU has detected an error in the leg current sensor.
False
No error has been detected in the leg current sensor.
When this occurs, the MCU will enter the open loop mode of operation and severely limits the
amount of torque the motor will produce.
