Engine•CVT total control signal (Multi communication)
Operation or Standard value measurement condition Refer to the “EC edition ECCS C/C input/output signal reference value”
Self diagnosis function CVT warning light display Caution: For vehicles except Hyper CVT-M6, the sport display light is used to function as the CVT warning light. • If faulty, the lighting duration of its pathway displays longer.
