The Diagnostic Tool can retrieve a list of information (provided by the
vehicle manufacturer), unique to the vehicle under test, from the
vehicle's on-board computer. This information may include:
„ The vehicle's VIN number

„ The vehicle's calibration ID(s). These IDs uniquely identify the
software version(s) for the vehicle's control module(s).
„ The Vehicle's Calibration Verification Number(s) (CVNs) required by
ODB2 regulations. CVNs are used to determine if emission-related
calibrations for the vehicle under test have been changed. One or
more CVNs may be returned by the vehicle's computer.
