    NOTE:
    • Do not spray cleaning fluid to ETC module directly and use a lint free cloth moistened by cleaning fluid.
    • Be careful not to clean the coating fluid around the shaft. If coating fluid is removed, idling control failure might occur by foreign substance inflow or excessive air leakage.
