Rod Adjustment Procedure Flow Chart

  1. Cool down the heat of the turbo charger sufficient enough so that the temperature of the coolant drops below 25°C (77°F).
  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. Check "Adaption value for the lower mechanical stop of EWGA" after selecting "Current Data" menu.

    Specified voltage value:  3.8 ± 0.1V

  8. If the coolant temperature is below 25°C (77°F) and the EWGA's adoption value for the lower mechanical stop is out of the specification, readjust the length of the rod as shown below.
    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.
      • If output voltage > 3.9V: 

        Turn it clockwise (D)

      • If output voltage > 3.7V: 

      Turn it counterclockwise (E)

    Turning angle Changing level of the adoption value (V)
    0.5 turn (180°) 0.15 - 0.20
    1 turn (360°) 0.30 - 0.40

  9. Install the rod end part (C) to the turbo charger lever (D) temporarily. Don't tighten the rod end lock nut (A).
  10. Turn the ignition switch ON/OFF 5 times. But hold 5 seconds at each IG ON or OFF state.
    NOTE:
    • Turn the ignition switch ON/OFF repeatedly until the changing value of "Adaption value for the lower mechanical stop of EWGA" is within 0.05V.

    When turning the ignition switch ON or OFF once, maximum changing level of the adoption value: 

    Max. ± 0.05V

  11. If the voltage value measured is not within the specified voltage value, repeat 8-10 procedures until the voltage value is within the specified voltage value.

    Specified voltage value:  3.8 ± 0.1V

  12. Check that "Adaption value for the lower mechanical stop of EWGA" is within the specified voltage value.
  13. If it is within the specified voltage value, install the turbo charger lever (D) and the rod end part (C).
    CAUTION:
    • Be careful not to remove the washer (E).
  14. Tighten the rod end locking nut (A). The turbo charger lever (D) side and the rod end part (C) side should be parallel at this time.
  15. Install the C-ring (B).
