Speed meter indication error Speed Meter indicates speed and actual speed according to formula :
O less than or equal to Vn-VZ less than or equal to (V: + 10) + 4
V1- speed meter indicates speed in km/h
V2- an actual speed in kilometers per hour (km/h).
The vehicle speed correction is based on 100km/h.
The error of the vehicle in the low speed state is the reason why the original vehicle meter is not linearly displayed.
