    NOTE:
    • Do not spray cleaner directly onto ETC module.
    • Do 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 material getting into the bearing of the shaft.
