  1. Check that the waste gate turbo charger is cool enough to work.

    Information 

    • It can help cooling down fast to use a electric fan.
    • The cooling part (A) and the wind direction (B) are as follows.

  2. Turn the ignition switch to OFF position.
  3. Connect the diagnostic tool to DLC connector (16 pin) under the driver side instrument panel.
  4. Turn the ignition switch ON position.
    CAUTION: Do not start the engine.
  5. Select VIN or Vehicle on the initial screen.
  6. Enter "Engine Control" menu after selecting vehicle information (Vehicle model, Model year, Engine type) or entering the VIN number.
  7. Access to KDS Engine < Current Data
  8. Without starting the engine, cycle the ignition ON for 5 seconds then ignition OFF for 5 seconds then check the "Adaptation value for the low mechanical stop of EWGA" on the KDS.

    Repeat this step until the amount of the adaptation value change compared to previous cycle is below 0.05V.

    NOTE: Do not start the engine. This is a crucial step to read the correct adaptation value.
  9. Check that "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage value.

    Voltage:  3.5 - 3.7 V

  10. If the voltage value measured is not within the specified voltage value, adjust the EWGA rod length. But, if no, no further procedure is required.
    1. Loosen the rod end lock nut (A) and remove the C-ring (B).
    2. Adjust the rod end part (C) by rotating it clockwise (D) or counterclockwise (E) to satisfy the specification.

      For example, if the coolant temperature is below 25°C adjusted as follows.

      Adaptation value for the lower mechanical stop of EWGA (V) Adjustment direction of rod end Rod length variation (After adjustment)
      > 3.7 counterclockwise Longer
      < 3.5 clockwise Shorter

      Information 

      Turning angle Changing level of the adaptation value (V)
      0.5 turn (180°) About 0.1
      1 turn (360°) About 0.2

  11. Install the rod end (B) to the turbo charger lever (A) temporarily. Don't tighten the rod end lock nut (C) and C-ring (D).

  12. Check "Adaptation value for the lower mechanical stop of EWGA" after selecting "Current Data" menu.

    Turn the ignition switch ON/OFF repeatedly until the changing value of "Adaptation value for the lower mechanical stop of EWGA" is within 0.05V.

    NOTE: Turn the ignition switch ON/OFF. But hold 5 seconds at each IG ON or OFF state.
  13. If the voltage value measured is not within the specified voltage value, repeat 9-12 procedures until the voltage value is within the specified voltage value.
  14. Check that "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage value.
  15. If it is within the specified voltage value, install the rod end to the turbo charger lever.
    1. Install the rod end (B) to the turbo charger lever (A).
    2. Tighten the rod end lock nut (C).
    3. Install the C-ring (E).
    NOTE:
    • Be careful not to remove the washer (D).
