On-Vehicle Inspection [08/2015 - ]: Procedure

  1. CHECK THROTTLE BODY WITH MOTOR ASSEMBLY 
    1. Before cleaning, or after cleaning the throttle body with motor assembly and installing it to the vehicle, turn the ignition switch ON without operating the accelerator pedal sensor assembly.
      NOTE:

      If the accelerator pedal sensor assembly has been operated, restart the procedure from the step above.

    2. Connect the Techstream to the DLC3 and check for DTCs. If DTCs are stored, repair them by following the repair procedure flow. If DTCs are not stored, perform the throttle body operation check.
    3. Check throttle body operation.
      1. Enter the following menus:

        Powertrain / Engine / Active Test / Control the ETCS Open/Close Slow Speed

      2. During Active Test operation, check the Data List items "Throttle Position Command" and "Throttle Position Sensor No. 1 Voltage".

        *a Correct *b Incorrect
        *c Throttle Position Command *d Throttle Position Sensor No. 1 Voltage
        *e Specified Condition *f 200 ms

        Standard Resistance

        Tester Display Condition Specified Condition
        Throttle Position Command Throttle Position Sensor No. 1 Voltage Checked during Active Test operation at a voltage of 1.3 V to 2.1 V. Response lag between Throttle Position Command and Throttle Position Sensor No. 1 Voltage is within 200 ms.
      3. Enter the following menus:

        Powertrain / Engine / Active Test / Control the ETCS Open/Close Fast Speed

      4. During Active Test operation, check the Data List items "Throttle Position Command" and "Throttle Position Sensor No. 1 Voltage".

        *a Correct *b Incorrect
        *c Throttle Position Command *d Throttle Position Sensor No. 1 Voltage
        *e Specified Condition *f 200 ms

        Standard Resistance

        Tester Display Condition Specified Condition
        Throttle Position Command Throttle Position Sensor No. 1 Voltage Checked during Active Test operation at a voltage of 1.3 V to 2.1 V. Response lag between Throttle Position Command and Throttle Position Sensor No. 1 Voltage is within 200 ms.
    4. Check the throttle control motor operating sounds.
      1. Turn the ignition switch to ON.
      2. When depressing the accelerator pedal, check the operating sound of the running motor. Make sure that no friction noises are emitted from the motor. If friction noise exists, replace the throttle body with motor assembly.
    5. Check the throttle position sensor.
      1. Connect the Techstream to the DLC3.
      2. Turn the ignition switch to ON.
      3. Turn the Techstream on.
      4. Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No. 1 Voltage %.
      5. Depress the accelerator pedal. When the throttle valve is fully opened, check that the value of "Throttle Position Sensor No. 1 Voltage %" is within the specification.

        Standard throttle valve opening percentage

        60% or more

        HINT: 

        When checking the standard throttle valve opening percentage, the shift position should be in N (neutral).

        If there was any abnormality found during the throttle body operation check or "Throttle Position Sensor No. 1 Voltage %" check, clean the throttle body, then reassemble it and perform the throttle body operation check again. If the operation returns to normal, the procedure is complete. If operation does not return to normal, replace the throttle body with motor assembly.
