Can a 4S shop detect odometer rollback?

[Ken]

4S shops can detect odometer rollback. They can determine whether the odometer has been tampered with based on maintenance records and professional diagnostic computer tests. For some automatic transmission models, the diagnostic computer can also check the transmission mileage to verify if the odometer has been rolled back. This can be done by connecting the diagnostic computer to the OBD interface. Odometer rollback is a common phenomenon in the used car market, as some buyers place great importance on a car's mileage, leading to this practice. When purchasing a used car, it's not necessary to focus too much on the mileage. What's more important than the mileage is the vehicle's maintenance condition and its usual operating environment.
