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

   Information 

   • It helps to cool engine down if an electric fan is used.
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 the vehicle information (Vehicle model, Model year, Engine type) or entering the VIN number.
7. Access to KDS Engine > Data Analysis
8. Without starting the engine, turn the ignition ON for 5seconds then ignition OFF for 5seconds then check the "Adaption value for the low mechanical stop of Electric Waste Gate Actuator (EWGA)" on the KDS.

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

   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 measured voltage value is not within the specified voltage value, adjust the EWGA rod length.
    1. Remove the retaining ring (B) from the EWGA rod (A).

    2. Remove the EWGA rod (A).

       NOTE: Be careful not to lose the retaining ring when removing it.
    3. Adjust the rod end part (A) by rotating it clockwise (C) or counterclockwise (B) to set within the specification.

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

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

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

    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. If it is within the specified voltage value, install the retaining ring (B) after tightening the lock nut (A).
