STEP 1. Check of harness damage in WGM+ line between turbocharger wastegate actuator connector and ECM connector.
STEP 2. Check of harness damage in WGM- line between turbocharger wastegate actuator connector and ECM connector.
STEP 3. Check of harness damage in WGMG line between ECM connector and ground.
STEP 4. Check of harness damage in WGP5 line between turbocharger wastegate actuator connector and ECM connector.
STEP 5. Check of harness damage in WGPS line between turbocharger wastegate actuator connector and ECM connector.
STEP 6. Check of harness damage in WGPG line between turbocharger wastegate actuator connector and ECM connector.
STEP 7. Check turbocharger wastegate actuator.
STEP 8. Check turbocharger assembly.
(1) Visually check the turbine wheel and the compressor wheel for cracking or other damage.
(2) Check whether the turbine wheel and the compressor wheel can be easily turned by hand.
(3) Check for oil leakage from the turbocharger assembly.note | When the wastegate valve is usual, it controls it as follows. Ignition switch "Lock" (OFF) position: Open Ignition switch "ON" position: Close |
Are there any abnormalities?
Replace the turbocharger assembly. Then go to Step 10. Go to Step 9.
STEP 9. Check the trouble symptoms.
STEP 10. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P226C set?
Retry the troubleshooting. The inspection is complete.
