Rod Adjustment Procedure Flowchart

  1. Check that the waste gate turbocharger is cool enough to work on.
    IMPORTANT:
    • Use an electric fan to help cool down fast.
    • The area to be cooled (A) and the wind direction (B) are as shown in illustration below.

  2. Switch "OFF" the ignition.
  3. Connect the diagnostic tool to DLC connector (16 pin) under the driver side instrument panel.
  4. Switch "ON" the ignition.
    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 GDS Engine > Current Data.
  8. Without starting the engine, cycle the ignition "ON" for 5 seconds then "OFF" for 5 seconds to check the "Adaptation value for the low mechanical stop of EWGA" on the GDS.

    Repeat this step until the change in adaptation value from 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 the "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage range.
    Coolant temperature (°C) Specified voltage range (V)
    50 - 60 3.6 - 3.8
    30 - 40 3.65 - 3.95
    Below 25 3.7 - 3.9
  10. If the measured voltage is not within the specified voltage range, adjust the EWGA rod length. Otherwise, no further procedure is required.
    1. Loosen the rod end lock nut (A) and remove the C-ring (B).
    2. Adjust the rod end (C) by rotating it clockwise (D) or counterclockwise (E) to satisfy the specification.

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

    Adaptation value for the lower mechanical stop of EWGA (V) Adjustment direction of rod end Rod length variation (After adjustment)
    > 3.9 clockwise Shorter
    < 3.7 counterclockwise Longer

    Information 

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

  11. Install the rod end (B) to the turbocharger 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.

    Switch ON/OFF the ignition repeatedly until the change in "Adaptation value for the lower mechanical stop of EWGA" is within 0.05V.

    NOTE:
    • Switch ON/OFF the ignition pausing for 5 seconds in each ignition status.

  13. If the measured voltage is not within the specified voltage range, repeat procedures  9-11 until the voltage is within the specified voltage range.
  14. Check that the "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage range.
  15. If it is within the specified voltage range, install the rod end to the turbocharger lever.
    1. Install the rod end (B) to the turbocharger lever (A).
    2. Tighten the rod end lock nut (C).
    3. Install the C-ring.
    NOTE:
    • Be careful not to remove the washer (D).
