Screen Used Cars for Mileage Inconsistencies
The CS310 reads mileage values from supported engine, transmission, ABS and instrument modules and compares them with the dashboard odometer, adding VIN, fault-code and port-voltage context to a used-car inspection. It reads and compares mileage only; it cannot change or correct it, and supported modules vary by vehicle.

- Porsche history and high-RPM records are references only and do not by themselves prove fraud, abuse or mechanical condition.
FAQ
Can the CS310 change or correct odometer mileage?
No. It reads and compares mileage data only.
Do matching mileage values prove the odometer is original?
No. They only show that the values read did not reveal a difference. Review unavailable modules, service history, body and mechanical condition, and an independent inspection.
Does the voltage display test battery health?
No. It shows voltage at the OBD connector. A full 12 V battery assessment needs a proper battery test.
