Car Reaction: Emergency Stop.
Troubleshooting: May be related to faulty motor field module, iBox, or invalid motor field calibration.
1. If excessive faults (fault) generated, module is disabled and should not be outputting voltage. If this is
not the case, there may be a problem with the motor field module.
2. Calibrate the motor field. During calibration, the current and voltage should start at their maximum value
and decrease as calibration proceeds. If this is not the case, there may be a problem with the iBox.
