Possible causes

  • Faulty Inverter With Converter Assembly
  • Inverter With Converter Assembly harness is open or shorted
  • Inverter With Converter Assembly circuit poor electrical connection
  • Tech notes

    Toyota recently released a warranty enhancement for 2010-2014 Prius, extending the coverage of the inverter/converter Intelligent Powertrain Module.

    Toyota Bulletin Information:
    Toyota has received some reports where the Intelligent Power Module (IPM) located inside the inverter assembly of the hybrid system may fail. This condition is indicated by hybrid system diagnostic trouble codes (DTCs): P0A94, P324E, P3004, and/or P0A1A. If one or more of these DTCs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter fail safe mode.
    Although the Hybrid Inverter assembly is covered by Toyota’s New Vehicle Limited Warranty for 8 years or 100,000 miles (whichever occurs first), we at Toyota care about the customers’ ownership experience. Toyota is now extending the warranty coverage for repairs related to failure of the Intelligent Power Module (IPM).

    Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • P3004 Toyota Description

    If the inverter voltage is not decreased after discharge with the ignition switch OFF, the VM sensor in the inverter is determined as defective. The ECU sets the OBDII code when HV battery voltage becomes lower than inverter voltage.
