PROCEDURE


  1. READ VALUE USING GTS (RANGE SENSOR VOLTAGE)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Enter the following menus: Powertrain / Transmission / Data List / Park Pawl Position Sensor Voltage "A", Park Pawl Position Sensor Voltage "B".


      Powertrain > Transmission > Data List
      Tester Display
      Park Pawl Position Sensor Voltage "A"
      Park Pawl Position Sensor Voltage "B"

    4. Depress the brake pedal and move the shift lever to select neutral (N).

    5. Push the P position switch (shift position indicator) to select park (P).

    6. Read the Data List according to the display on the GTS.

  2. CHECK HARNESS AND CONNECTOR (SHIFT CONTROL ECU - RANGE SENSOR (SHIFT CONTROL ACTUATOR ASSEMBLY))


    1. Disconnect the A50 shift control ECU connector.

    2. Disconnect the D32 range sensor (shift control actuator assembly) connector.

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      A50-19 (VCNS) - D32-1 (VCNS) Always Below 1 Ω
      A50-20 (NS1) - D32-2 (NS1) Always Below 1 Ω
      A50-18 (NS2) - D32-4 (NS2) Always Below 1 Ω
      A50-17 (E2NS) - D32-3 (E2NS) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      A50-19 (VCNS) or D32-1 (VCNS) - Body ground and other terminals Always 10 kΩ or higher
      A50-20 (NS1) or D32-2 (NS1) - Body ground and other terminals Always 10 kΩ or higher
      A50-18 (NS2) or D32-4 (NS2) - Body ground and other terminals Always 10 kΩ or higher
      A50-17 (E2NS) or D32-3 (E2NS) - Body ground and other terminals Always 10 kΩ or higher

    4. Reconnect the D32 range sensor (shift control actuator assembly) connector.

  3. CHECK SHIFT CONTROL ECU (VCNS VOLTAGE)


    1. Disconnect the D32 range sensor (shift control actuator assembly) connector.

    2. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      D32-1 (VCNS) - D32-3 (E2NS) Engine switch on (IG) 4.5 to 5.5 V

      Note

      Turning the engine switch on (IG) with the connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    4. Turn the engine switch off.

    5. Reconnect the D32 range sensor (shift control actuator assembly) connector.
