OBD II Fault Code


    OBD-II Code High voltage system may not operate is defined as a Drive Motor "A" Phase U-V-W Current Sensor Correlation

    The Drive Motor Generator Power Inverter Control Module consists of two Motor Control Modules and the Hybrid Powertrain Control Module. Because the two Motor Control Modules are wired together, the current flowing through both modules should be the same. If they are not, code P0BFD is set. The High Voltage System will be disabled.
