4.6 Request Vehicle Information
Vehicle Information allows to request the vehicle’s VIN number, calibration ID(s) which identifies
software version in vehicle control module(s), calibration verification numbers (CVN(s)) and
in-use performance tracking on model year 2000 and newer OBD II compliant vehicles.
CVNs are calculated values required by OBD II regulations. They are reported to check if
emission-related calibrations have been changed. Multiple CVNs may be reported for a control
module. It may take several minutes to do the CVN calculation. In-use performance tracking
tracks performance of key readiness monitors.

Available options will vary depending on the vehicle under test.
