Code No.25 Wrong-diameter tireProbable cause
Code No.25 is output as wrong-diameter tire when one of the four vehicle
speeds is outside the range of specified values in respect to the average of the
four vehicle speed sensors, when the vehicle speed is above 20 km/h with the
steering wheel in the straight ahead position.
