DESCRIPTION

The MG ECU located in the inverter with converter assembly monitors the generator inverter current sensors. P0A72 and P0A75 indicate malfunctions in the current sensors. They do not indicate malfunctions in the high-voltage system.

DTC No. INF Code DTC Detection Condition Trouble Area
P0A72 326 Malfunction in generator inverter current sensor (phase V sub sensor)

  • Inverter with converter assembly

  • Service plug grip
P0A72 328 Malfunction in generator inverter current sensor (phase V main sensor)
P0A72 333 Malfunction in generator inverter current sensor (performance problem or open phase V)
P0A72 515 Malfunction in generator inverter current sensor (phase V main and sub sensors offset)
P0A75 334 Malfunction in generator inverter current sensor (phase W sub sensor)
P0A75 336 Malfunction in generator inverter current sensor (phase W main sensor)
P0A75 341 Malfunction in generator inverter current sensor (performance problem or open phase W)
P0A75 516 Malfunction in generator inverter current sensor (phase W main and sub sensors offset)

PROCEDURE


  1. CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CONNECTOR)

    Note

    Before disconnecting the connector, confirm that it is properly connected by checking that the locking claws are engaged and that the connector cannot be pulled out.


    1. Check the connection of the low voltage connector of the inverter with converter assembly.

      OK
      The connector is connected securely and there are no contact problems.

      Tech Tips


      • When connecting the connector, insert it with the locking lever in the raised position. Rotate the lever downward and make sure that the connector is pulled into its socket. When the locking lever is in its fully closed position, a click will be heard as its locking claws engage. After the click is heard, pull up on the connector to confirm that it is properly connected.

      • If any DTCs indicating malfunctions in the current sensor circuit are output, overcurrent to the electric battery fuse may be the cause. In this case, be sure to replace the service plug grip after troubleshooting and performing repairs for all output DTCs.
