Traction motor temperature too high.

Possible Causes:
- Excessive pushing or stalling of traction motor.
- Operation may continue at slower duty cycle.

- Comparing the motor temperature through the display panel with a known motor temperature, such as room temperature, can check the motor temperature sensor.
- A shorted or open temperature sensor will generate a status code 43.
