  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS 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 2 minutes or more.

  5. Turn the power switch on (IG) and turn the GTS on.

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

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

  8. Check the DTC judgment result.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.

PROCEDURE


  1. CLEAR DTC


    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. Read and record the DTCs and freeze frame data.


      Powertrain > Hybrid Control > Trouble Codes

    5. Clear the DTCs and freeze frame data.


      Powertrain > Hybrid Control > Clear DTCs

    6. Turn the power switch off.

  2. READ VALUE USING GTS (OPM TEMPERATURE))


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Data List / OPM Temperature.

    4. Read the Data List.

      Result
      Result Proceed to
      -40°F (-40°C) (open or short to +B) A
      Approximately equal to the actual temperature B

    5. Turn the power switch off.

      *a

      Rear view of wire harness connector

      (to Hybrid Vehicle Control ECU Assembly)

      Disconnect the hybrid vehicle control ECU assembly connector.

    2. Turn the power switch on (IG).

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A22-30 (TOPM) - A22-31 (ETOP) or Body ground Power switch on (IG) Below 1 V

      Note

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

    4. Turn the power switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A22-30 (TOPM) - A22-31 (ETOP) 68°F (20°C) 11.94 to 12.22 kΩ
      A22-30 (TOPM) - A22-31 (ETOP) 104°F (40°C) 5.75 to 5.92 kΩ
      A22-30 (TOPM) - A22-31 (ETOP) 176°F (80°C) 1.63 to 1.71 kΩ

    6. Reconnect the hybrid vehicle control ECU assembly connector.

      Result

  4. CHECK OIL WITH MOTOR PUMP ASSEMBLY (OIL PUMP MOTOR TEMPERATURE SENSOR)


    1. B000TK4

      Disconnect the oil pump motor temperature sensor connector.

    2. Turn the power switch on (IG).

    3. B000R79C08
      *1 Oil Pump Motor Temperature Sensor

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      G37-1 (OMT) - G37-2 (OMTG) Power switch on (IG) Below 1 V
      G37-2 (OMTG) - Body ground Power switch on (IG) Below 1 V

      Note

      Turning the power switch on (IG) with the oil pump motor temperature sensor connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    4. Turn the power switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      G37-1 (OMT) - G37-2 (OMTG) 68°F (20°C) 11.94 to 12.22 kΩ
