    NOTE:
    • Do not spray a cleanser directly to ETC module. Use a soft and lint-free cloth to clean carbon.
    • Be careful not to wipe out coating (A) around the shaft. If the coating is removed, poor idling control can be caused by excessive air leakage or foreign materials in the bearing of the shaft.
  4. After cleaning it, reinstall the ETC module and perform ETC module learning procedure.
