Rod Adjustment Procedure Flowchart
- Check that the waste gate turbocharger is cool enough to work on.
Information
- Switch "OFF" the ignition.
- Connect the diagnostic tool to DLC connector.
- Switch "ON" the ignition.CAUTION:
- Do not start the engine.
- Select VIN or Vehicle on the initial screen.
- Enter "Engine Control" menu after selecting vehicle information (Vehicle model, Model year, Engine type) or entering the VIN number.
- Access to diagnostic tool Engine > Current Data
- Without starting the engine, repeatedly turn the ignition ON for 5 seconds and OFF for 5 seconds, and then check the "Adaptation value for low mechanical stop of EWGA" on the diagnostic tool.
Repeat this step until the amount of difference in the adaptation value from the previous cycle is below 0.05 V.
- Check that the "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage range.
Coolant Temperature [°C (°F)] Specification 50 - 60 (122 - 140) 3.6 - 3.8 30 - 40 86 - 104) 3.65 - 3.95 Below 25 (Below 77) 3.7 - 3.9 - If the measured voltage is not within the specified voltage range, adjust the EWGA rod length. Otherwise, no further procedure is required.
- Loosen the rod end lock nut (A) on the turbo side and remove the C-ring (B).
- 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 (77°F), 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 NOTE:- The lower limit of the adaptation value for the mechanical stop of EWGA is between 3.2V and 4.85V (based on the cooling water temperature of 25°C). If the adaptation value is below 3.2V or above 4.85V, the ECM will recognize it as EWGA failure and adjustment of the previous adaptation value becomes impossible.
- When it becomes impossible to make adjustments, replacement of EWGA is necessary. So, be careful not to exceed the limit value when adjusting the load.
Information
Turning angle Changing level of the adaptation value (V) 0.5 turn (180°) 0.08 - 0.11 1 turn (360°) 0.16 - 0.22
- Install the rod end (B) to the turbocharger lever (A). But, do not tighten the locking nut (C) and do not install the C-ring (D).
- 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.
- If the measured voltage is not within the specified voltage range, repeat procedures 9-11 until the voltage is within the specified voltage range
- Check that the "Adaptation value for the lower mechanical stop of EWGA" is within the specified voltage range.
- If it is within the specified voltage range, install the rod end to the turbocharger lever.
- Temporarily install the load end (B) to the turbocharger lever (A).
- Tighten the rod end lock nut (C).
- Install the C-ring (E).NOTE:
- Be careful not to remove the washer (D).
