Rod Adjustment Procedure Flowchart
- Check that the waste gate turbo charger is coolenough to work.
Information
- Use an electric fan to cool down fast.
- The cooling part (A) and the wind direction (B) areas follows.
- Turn the ignition switch to OFF position.
- Connect the diagnostic tool to DLC connector (16pin) under the driver side instrument panel.
- Turn the ignition switch ON.CAUTION:
- Do not start the engine.
- Select VIN or Vehicle on the initial screen.
- Enter "Engine Control" menu after slelecting vehicleinformation (Vehicle model, Model year, Engine type)or entering the VIN number.
- Access to diagnostic tool Engine > Current Data
- Without starting the engine, repeatedly turn theignition ON for 5 seconds and OFF for 5 seconds, and then check the "Adaptation value for lowmechanical stop of EWGA" on the diagnostic tool.
Repeat this step until the amount of difference in theadaptation value from the previous cycle is below 0.05V.
- Check that "Adaptation value for the lowermechanical stop of EWGA" is within the specifiedvoltage value.
Coolant temperature (°C) Specified voltage value (V) 50 - 60 3.6 - 3.8 30 - 40 3.65 -3.95 Below 25 3.7 - 3.9 - If the measured voltage value is not within thespecified voltage value, adjust the EWGA rodlength. Otherwise, no further procedure is required.
- Loosen the rod end lock nut (A) and remove the C-ring (B).
- Adjust the rod end part (C) by rotating it clockwise(D) or counterclockwise (E) to satisfy thespecification.
For example, if the coolant temperature is below 25°C, adjust as follows.
Adaptation valuefor the lower mechancalstop of EWGA (V) Adjusting directionof rod end Rod length variation (After adjustment) > 3.9 clockwise Shorter < 3.7 counterclockwise Longer NOTE:- The lower limit of the adaptation value for themechanical stop of EWGA is between 3.2Vand 4.85V (based on the cooling watertemperature of 25°C). If the adaptation valueis below 3.2V or above 4.85V, the ECM willrecognize it as EWGA failure andadjustment of the previous adaptation valuebecomes impossible. When it becomesimpossible to make adjustments, replacement of EWGA is necessary. So, becareful not to exceed the limit value whenadjusting the load.
Turning angle Changing level of the adaptationvalue (V) 0.5 turn (180°) 0.15 - 0.20 1 turn (360°) 0.30 - 0.40
- The lower limit of the adaptation value for themechanical stop of EWGA is between 3.2Vand 4.85V (based on the cooling watertemperature of 25°C). If the adaptation valueis below 3.2V or above 4.85V, the ECM willrecognize it as EWGA failure andadjustment of the previous adaptation valuebecomes impossible. When it becomesimpossible to make adjustments, replacement of EWGA is necessary. So, becareful not to exceed the limit value whenadjusting the load.
- Install the rod end (B) to the turbocharger lever (A)temporarily. Do not tighten the rod end lock nut (C)and C-ring (D).
- Check the "Adaptation value for the lower mechanicalstop of EWGA" after selecting "Current Data" menu Turn the ignition switch ON/OFF repeatedly until the changing value of the "Adaptation value for the lowermechanical stop of EWGA" is within 0.05V.
- If the measured voltage value is not within thespecified voltage value, repeat procedures 9-11 untilthe voltage value is within the specified voltagevalue.
- Check that the "Adaptation value for the lowermechanical stop of EWGA" is within the specifiedvoltage value.
- If it is within the specified voltage value, install therod end to the turbocharger lever.
- Install the rod end (B) to the turbocharger lever (A).
- Tighten the rod end lock nut (C).
- Install the C-ring (E).
