Can car mileage be adjusted?
1 Answers
Car mileage can be adjusted, and general auto repair shops as well as automotive electrical repair points can perform this adjustment. Main reasons for adjusting the odometer: If the odometer itself has a malfunction and is then repaired, the mileage will naturally change as a result, which falls within the scope of normal repairs. If such a car is sold, the situation should be explained, and the previous mileage should be noted. Car odometers usually have four digits for short-term counting, which can be reset; the total mileage has six digits and cannot be reset. The accumulated mileage numbers on electronic odometers are stored in non-volatile memory, allowing the data to be preserved even without power. The vast majority of passenger cars use speedometers with electronic sensors instead of flexible shafts. A common method involves obtaining signals from the speed sensor on the transmission, where changes in pulse frequency cause the pointer to deflect or display digits indicating the car's speed. The car odometer also includes two LCD digital display windows connected to the same signal source, which respectively accumulate the current trip mileage and the total mileage. The accumulated mileage numbers on electronic odometers are stored in non-volatile memory, allowing the data to be preserved even without power.
