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. With the engine stopped and park (P) selected, depress the accelerator pedal to start the engine.

      Check MG1 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 MG1 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
        Tester Connection Condition Specified Condition
        f1-1 (W) - f1-2 (U) Power switch off 89.5 to 98.9 mΩ

        f1-3 (V) - f1-1 (W) Power switch off 89.5 to 98.9 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)

    5. 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.

      *3 Shield ground

      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.

      Standard Resistance
      Tester Connection Condition Specified Condition
      e1-1 (W) - Body ground and shield ground Power switch off 100 MΩ or higher
      e1-2 (U) - Body ground and shield ground Power switch off 100 MΩ or higher
      e1-3 (V) - Body ground and shield ground Power switch off 100 MΩ or higher

      Note

      Wrap the terminal of the three-phase AC cable with insulating tape to prevent them from coming into contact with body ground

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      e1-1 (W) - e2-1 (W) Power switch off Below 1 Ω
      e1-2 (U) - e2-3 (U) Power switch off Below 1 Ω
      e1-3 (V) - e2-2 (V) Power switch off Below 1 Ω
      e1-1 (W) - e2-3 (U) Power switch off 100 MΩ or higher
      e1-2 (U) - e2-2 (V) Power switch off 100 MΩ or higher
      e1-3 (V) - e2-1 (W) Power switch off 100 MΩ or higher

    5. Install the motor cable.
