  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 OFF.
  3. Connect the diagnostic tool to data link connector (DLC).
  4. Turn the ignition switch ON.
    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. Select "Current Data".
  8. Without starting the engine, cycle the ignition ON for 5 seconds then ignition OFF for 5 seconds then check the "Adaption value for the low mechanical stop of EWGA" on the diagnostic tool.

    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 mechancal stop of EWGA" is within the specified voltage value.

    Voltage:  3.5 - 3.7V

  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.
      Adaption value for the lower mechancal 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 adaption 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 "Adaption value for the lower mechancial stop of EWGA" after selecting "Current Data" menu.

    Turn the ignition switch ON/OFF repeatedly until the changing value of "Adaption value for the lower mechancal 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 untill the voltage value is within the specified voltage value.
  14. Check that "Adaption value for the lower mechancal 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).
