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

    Information 

    • It helps to cool engine down if an electric fan is used.
    • Place electric fan and flow direction as shown in the image below (A) and (B).

  2. Turn the ignition OFF position.
  3. Connect the diagnostic tool to DLC connector (16 pin) under the driver side instrument panel.
  4. Turn the ignition 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 5seconds then ignition OFF for 5seconds then check the "Adaption value for the low mechanical stop of EWGA" on the KDS.

    Repeat this step until the amount of the adaption 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 adaption value.
  9. Check that "Adaption 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. Slightly loosen the rod end lock nut (A).

    2. Remove the rod (A) after removing the retaining rings.

    3. Adjust the rod end part by rotating it clockwise (A) or counterclockwise (B) to set within the specification.

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

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

      Information 

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

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

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

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

    NOTE: Turn the ignition 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 "Adaption 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 retaining ring after tightening the lock nut (A).
