Abstract
A diagnostic system and method for detecting odometer tampering by retrieving and comparing vehicle operation data, such as mileage-related data from multiple electronic control units (ECUs) through a vehicle's diagnostic link connector (DLC). The system accesses both standardized and non-standardized parameter identifiers (PIDs), including manufacturer-specific data from modules such as the engine control module (ECM), body control module (BCM), anti-lock braking system (ABS), and gateway module. By comparing the displayed odometer reading against internally stored or alternative mileage values, the system identifies inconsistencies indicative of tampering. Cloud-based historical data may be included to further enhance verification accuracy. The invention enables reliable odometer validation using data already embedded within the vehicle's electronic architecture.
