DTC P0BFD
- Drive Motor 1 Phase U-V-W Correlation
DTC P0BFE
- Drive Motor 2 Phase U-V-W Correlation
Circuit/System Description
The drive motor generator power inverter control module (PIM) contains two motor control modules (MCMs) and the hybrid powertrain control
module (HPCM). Each MCM operates its respective drive motor generator based upon HPCM commands. Each MCM controls the speed, direction
and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate
bipolar transistors (IGBTs). Each drive motor generator operates utilizing 3-phase alternating current (ac) electricity. Each IGBT operates a single
phase of the drive motor generator. Each phase is individually identified as U, V and W. Each MCM monitors the current of each phase in order to
detect PIM overcurrent conditions.
Because all the motor generator phase circuits are electrically joined together, they should each flow about the same amount of current. The MCM
performs a mathematical calculation to verify that the phase current sensors are accurate. If the U-V-W phase current sensors indicate about the
same amount of phase current, the sum of the calculation should be near zero. If the U-V-W phase currents are not similar, this DTC will set.
Conditions for Running the DTC
* The ignition is ON.
* The High Voltage contactor relays are closed.
Conditions for Setting the DTC
The sum of the 3 phase current sensors is greater than 75 A.
Action Taken When the DTC Sets
* DTCs P0BFD and P0BFE are Type A DTCs.

DTC Descriptor
DTC P0BFD
- Drive Motor 1 Phase U-V-W Correlation
DTC P0BFE
- Drive Motor 2 Phase U-V-W Correlation
Circuit/System Description
The drive motor generator power inverter control module (PIM) contains two motor control modules (MCMs) and the hybrid powertrain control
module (HPCM). Each MCM operates its respective drive motor generator based upon HPCM commands. Each MCM controls the speed, direction
and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate
bipolar transistors (IGBTs). Each drive motor generator operates utilizing 3-phase alternating current (ac) electricity. Each IGBT operates a single
phase of the drive motor generator. Each phase is individually identified as U, V and W. Each MCM monitors the current of each phase in order to
detect PIM overcurrent conditions.
Because all the motor generator phase circuits are electrically joined together, they should each flow about the same amount of current. The MCM
performs a mathematical calculation to verify that the phase current sensors are accurate. If the U-V-W phase current sensors indicate about the
same amount of phase current, the sum of the calculation should be near zero. If the U-V-W phase currents are not similar, this DTC will set.
Conditions for Running the DTC
* The ignition is ON.
* The High Voltage contactor relays are closed.
Conditions for Setting the DTC
The sum of the 3 phase current sensors is greater than 75 A.
Action Taken When the DTC Sets
* DTCs P0BFD and P0BFE are Type A DTCs.
* The PIM commands the battery energy control module (BECM) to open the high voltage contactor relays.
Conditions for Clearing the DTC
DTCs P0BFD and P0BFE are Type A DTCs.
