Overview
CS310 Used Car Odometer Scanner
The AUTOOL CS310 Used Car Odometer Scanner is an OBD-II mileage inspection tool designed specifically for the used-car industry. It reads original mileage data from multiple electronic control modules through the vehicle’s OBD interface and compares it with the dashboard mileage to quickly identify potential odometer tampering. It is an essential tool for used-car dealers, auto repair shops, and private buyers.
Working Principle
While dashboard mileage can be modified, multiple electronic control units, such as the engine ECU, transmission TCU, and ABS control unit, can retain original mileage data, making it difficult to alter or reset all mileage records simultaneously.
1.Connect the scanner to the vehicle’s OBD-II diagnostic port. Through the CAN bus, it reads original mileage data stored in the ECU, TCU, ABS, and body control modules.
2.Automatically compare multiple mileage records with the dashboard mileage. Any inconsistency between the readings can indicate possible odometer tampering.
3.Read the vehicle VIN, fault codes, and battery voltage at the same time to provide a more comprehensive view of the vehicle’s condition.
Features
Multi-Module Mileage Reading:Simultaneously reads mileage data from multiple modules, including the engine ECU, transmission TCU, ABS, and instrument cluster. By comparing the data, inconsistent mileage readings can quickly reveal potential odometer tampering, helping prevent buyers from relying solely on the dashboard mileage. For Porsche vehicles, the scanner additionally supports historical mileage records and aggressive driving record retrieval.
One-Touch VIN Reading:Automatically reads the vehicle identification number (VIN) to verify vehicle information and help identify accident-damaged or improperly assembled vehicles, reducing vehicle condition risks.
One-Touch OBD Fault Code Clearing:Reads full-vehicle fault codes and freeze-frame data and clears fault codes with one touch after repairs. It quickly clears the check engine light, making the scanner suitable for both used-car inspection and automotive repair.
Real-Time Battery Voltage Testing:Reads battery voltage directly through the OBD interface to quickly assess battery condition and identify low-voltage or battery discharge issues.
Practical Hardware Configuration:
2.8-inch TFT HD Color Display
Standard OBD-II Connector
USB Type-C Port for Firmware Updates
17 Languages, Including Simplified Chinese
Compact, Handheld Design for easy storage in an automotive tool case
Extensive Vehicle Coverage:Supports 47 major vehicle brands across Europe, America, and Asia, including Audi, BMW, Mercedes-Benz, Volkswagen, Toyota, Honda, Nissan, Ford, Buick, and Porsche. Compatible with OBD-II-equipped gasoline vehicles manufactured from 1996 onward.
Applications:
Used-Car Dealers: Inspect vehicles before purchase, identify potential odometer tampering, and reduce the risk of mileage fraud.
Auto Repair Shops: Combine mileage verification and fault diagnosis in one tool for versatile service applications.
Rental Car Companies: Monitor actual vehicle mileage for more accurate fleet management.
