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 (READY) and wait for 5 seconds or more.

  2. Perform a road test according to the freeze frame data and item "Vehicle Spd" for approximately 10 minutes.

      Motor Cable

      (Inverter with Converter Assembly Side)

      Check motor (MG2) for an interphase short using a milliohmmeter.


      1. Using a milliohmmeter, measure the resistance according to the value(s) in the table below.

        Tech Tips

        If the motor (MG2) temperature is high, the resistance will vary greatly from the specification. Therefore, measure the resistance at least 8 hours after the vehicle is stopped.

        Standard Resistance
        for LHD
        Tester Connection Switch Condition Specified Condition
        u1-3 (W) - u1-1 (U) Power switch off 47.0 to 51.8 mΩ
        u1-2 (V) - u1-3 (W) Power switch off 47.3 to 52.1 mΩ
        u1-1 (U) - u1-2 (V) Power switch off 47.1 to 51.9 mΩ
        for RHD
        Tester Connection Switch Condition Specified Condition
        u3-1 (W) - u3-3 (U) Power switch off 47.0 to 51.8 mΩ
        u3-2 (V) - u3-1 (W) Power switch off 47.3 to 52.1 mΩ
        u3-3 (U) - u3-2 (V) Power switch off 47.1 to 51.9 mΩ

        Tech Tips

        To correct the variation of the measured resistance due to temperature, use the following formula to calculate the resistance at 20°C (68° F).


        • R20 = Rt / {1 + 0.00393 X (T - 20)}

        The calculation is based on the following:


        • R20: Resistance at 20°C (68° F) (mΩ)

        • Rt: Measured resistance (mΩ)

        • T: Temperature when the resistance is measured (°C)

    6. When checking for a short circuit between motor phases without using a milliohmmeter.

      Note

      The motor generates current when wheels are rotated by hand. Before performing the inspection, wrap the motor cable terminals with insulation tape.

      Tech Tips

      A short circuit between the motor phases can be checked simply without using a milliohmmeter.


      1. Connect the cable to the negative (-) auxiliary battery terminal.

      2. Turn the power switch on (IG).

        Note

        Turning the power switch on (IG) with the service plug grip removed causes other DTCs to be stored. Clear the DTCs after performing this inspection.

      3. Move the shift lever to N.

      4. Lift up the vehicle.

      5. Rotate the rear wheels in the same direction simultaneously by hand.

        Standard
        Left and right wheels rotate smoothly (No short circuit between phases)

        Tech Tips

        If a short circuit exists between the motor phases, the rear wheels do not rotate smoothly (some resistance is felt).

      6. Lower the vehicle.

      7. Move the shift lever to P.

      8. Turn the power switch off.

      9. Disconnect the cable from the negative (-) auxiliary battery terminal.

    7. Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below.

      Note

      Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.

      A74-30 (HSDN) or A74-25 (HSDN) - Body ground Power switch on (IG) Below 1 V

      Note

      Turning the power switch on (IG) with the power management control ECU and inverter with converter assembly connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    7. Turn the power switch off.

    8. Disconnect the cable from the negative (-) auxiliary battery terminal.

    9. Measure the resistance according to the value(s) in the table below.

  10. CHECK INVERTER WITH CONVERTER ASSEMBLY

    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. Disconnect the A38*1 or A74*2 inverter with converter assembly connector.
