Code P1E2D Description

The power inverter module, often referred to as the drive motor generator power inverter module, contains three motor control modules and the hybrid powertrain control module. Two of the motor control modules operate their respective drive motor generator based upon power inverter module commands. The third motor control module controls the auxiliary transmission fluid pump motor. This is an internal fault detection of the power inverter module. This fault is handled inside the power inverter module and no external circuits are involved.
Each motor control module operates its respective drive motor based upon hybrid powertrain control module commands. Each motor control module controls its respective motor through the sequencing actuation of high-current switching transistors called insulated gate bipolar transistors. Each motor operates utilising 3-phase alternating current AC electricity. Each insulated gate bipolar transistor operates a single phase of the drive motor generator. Each phase is individually identified as U, V and W. Each motor control module monitors the current of each phase in order to detect out of range current conditions.
Because each individual motor's phase circuits are electrically joined together, the phases normally flow about the same amount of current. The motor control module 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.
