DTC SUMMARY

MALFUNCTION DESCRIPTION

These DTCs indicates current sensor value is abnormal. The cause of this malfunction may be one of the following:


  1. Internal inverter malfunction


    • Inverter with converter assembly internal circuit malfunction

  2. Inverter low-voltage circuit malfunction


    • The connectors are not connected properly

DESCRIPTION

The MG ECU, which is built into the inverter with converter assembly, monitors the main and sub sensors of the motor inverter current sensor. P0A60 and P0A63 indicate malfunctions in current sensors, and do not indicate malfunctions in the high-voltage system.

Tech Tips

The term "drive motor A" indicates motor (MG2).

MONITOR DESCRIPTION

The MG ECU monitors the motor inverter current sensor. If the MG ECU detects a current sensor malfunction, it sends a signal to the power management control ECU which will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

A01I3JNE02

  1. Connect the Techstream to the DLC3.

  2. Turn the power switch on (IG) and turn the Techstream on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for 30 seconds or more.

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

  6. Turn the Techstream on.

  7. Turn the power switch on (READY) with the shift lever in P, and wait for 5 seconds or more.

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

  9. Depress the accelerator pedal of the vehicle with the engine stopped and the shift lever in P to start the engine.

  10. Drive the vehicle forward with the shift lever in D for 5 m (16 ft.) or more. [A]

  11. Drive the vehicle backward with the shift lever in R for 5 m (16 ft.) or more. [B]

  12. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [C]

  13. Read the current DTCs.

    Tech Tips


    • If a current DTC is output, the system is malfunctioning.

    • If current DTCs are not output, perform the following steps to check for permanent DTCs.

  14. Check that permanent DTCs are cleared.

  15. If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.

INSPECTION PROCEDURE

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 the shift lever in P 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 the shift lever in P to start the engine.

  5. Drive the vehicle forward with the shift lever in D for 5 m (16 ft.) or more.

  6. Drive the vehicle backward with the shift lever in R for 5 m (16 ft.) or more.

PROCEDURE

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

    CAUTION:

    Be sure to wear insulated gloves.


    1. 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.

    2. Check the connection condition of the low voltage connector of the inverter with converter assembly and the contact pressure of each terminal. Check the terminals for deformation, and check the connector for water ingress and foreign matter Click here.

      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.

      A01I3MYE01
      OK
      - The connector is connected securely.
      - The terminals are not deformed and are connected securely.
      - No water or foreign matter in the connector.

      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.
