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.

    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.

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

  4. Keep the engine running for 5 seconds or more.

  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.


  • *: Lightly wiggle the connectors and wire harnesses up and down and right and left.

    Note

    If excessive pressure is applied while the connectors and wire harnesses are wiggled, they may be damaged. After the inspection, make sure to return the wire harnesses and clamps to their original position.

      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.

      Component without harness connected

      (Motor Resolver (Hybrid Vehicle Transaxle Assembly))

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      1 (MRF) - 4 (MRFG) Power switch off 5.8 to 11.8 Ω
      2 (MSN) - 5 (MSNG) Power switch off 11.7 to 17.7 Ω
      3 (MCS) - 6 (MCSG) Power switch off 11.7 to 17.7 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      1 (MRF) - Body ground and other terminals (except 4 (MRFG)) Power switch off 1 MΩ or higher
      4 (MRFG) - Body ground and other terminals (except 1 (MRF)) Power switch off 1 MΩ or higher
      2 (MSN) - Body ground and other terminals (except 5 (MSNG)) Power switch off 1 MΩ or higher
      5 (MSNG) - Body ground and other terminals (except 2 (MSN)) Power switch off 1 MΩ or higher
      3 (MCS) - Body ground and other terminals (except 6 (MCSG)) Power switch off 1 MΩ or higher
      6 (MCSG) - Body ground and other terminals (except 3 (MCS)) Power switch off 1 MΩ or higher

      Tech Tips

      The motor resolver is not available as a supply part. If it requires replacement, replace the hybrid vehicle transaxle assembly.

    3. Reconnect the C44 motor resolver connector.
