Code P1E2F GMC Description
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.
What are the Possible Causes of the DTC P1E2F GMC?
- Program Power Inverter Module
- Faulty Power Inverter Module
- Power Inverter Module harness is open or shorted
- Power Inverter Module circuit poor electrical connection
