Can the Total Mileage of a Car Be Reset?

Can the total mileage of a car be reset. Mechanical odometer: The mechanical odometer consists of worm gear mechanisms and numeral wheels. When the car is in motion, the drive shaft rotates the rightmost first numeral wheel through three sets of worm gears, displaying 1/10km on the first numeral wheel. From the first numeral wheel to the left, every two adjacent numeral wheels are connected through their internal teeth and carry-over gears, forming a 10:1 gear ratio. Electronic odometer: The electronic speedometer and odometer system consists of a speed sensor (installed on the worm gear assembly of the transmission on the wheel, utilizing either photoelectric or magnetoelectric principles), a microprocessor system, and a display unit. The photoelectric or magnetoelectric pulse signals transmitted by the sensor are processed by the internal microprocessor of the instrument, displaying the vehicle speed on the screen. The odometer calculates and displays the mileage based on the vehicle speed and accumulated operating time, processed by the microprocessor.
I'm quite qualified to speak on this, as I've seen many similar cases during my time at the repair shop. While a car's total mileage can theoretically be reset, the actual process is extremely complex and illegal. Modern vehicle odometer data is stored in tamper-proof chips that require specialized equipment to rewrite. My neighbor learned this the hard way after purchasing a rolled-back used car - they later discovered severe engine wear and spent over ten thousand on major repairs. Even if the numbers are altered, telltale signs of wear on the chassis and tires can't be hidden. Used car dealers often employ odometer fraud, so always check official maintenance records or use diagnostic tools to read the transmission's actual mileage when buying used. Remember, odometer tampering is illegal and can lead to serious legal consequences if discovered.
