DESCRIPTION

The MG ECU located in the inverter with converter assembly monitors the motor inverter current sensors. P0A60 and P0A63 indicate malfunctions in current sensors, and they do not indicate malfunctions in the high-voltage system.

Tech Tips

The term "drive motor A" indicates MG2.

290 Malfunction in motor inverter current sensor (phase V main sensor)
294 Malfunction in motor inverter current sensor (performance problem or open phase V)
501 Malfunction in motor inverter current sensor (phase V main and sub sensors offset)
P0A63 296 Malfunction in motor inverter current sensor (phase W sub sensor)
298 Malfunction in motor inverter current sensor (phase W main sensor)
302 Malfunction in motor inverter current sensor (performance problem or open phase W)
502 Malfunction in motor inverter current sensor (phase W main and sub sensors offset)

CAUTION / NOTICE / HINT

CAUTION:


  • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work Click here.

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

Note

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Turn the power switch on (IG) and wait for 5 seconds or more.

  2. Turn the power switch on (READY) with park (P) selected and wait for 5 seconds or more.

  3. Move the shift lever to N and wait for 5 seconds or more.

  4. Depress the accelerator pedal of the vehicle with the engine stopped and park (P) selected to start the engine.

  5. Drive the vehicle forward with drive (D) selected for 5 m or more.

  6. Drive the vehicle backward with reverse (R) selected for 5 m or more.

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Check if DTCs are output.

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

    CAUTION:

    Be sure to wear insulated gloves.


    1. A005CAR

      Check that the service plug grip is not installed.

      Note

      After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.

      Note

      Before disconnecting the connector, confirm that it is properly connected by checking that the locking claws are engaged and that the connector does not pull out.

    2. 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.
