Global OBD II Diagnostics

Calibration Verification Numbers (CVNs) are calculated values required by OBD II regulations. CVNs are reported to determine if emission-related calibra- tions have been altered. Multiple CVNs may be reported for a control module.

The calculation may take several minutes the first time the CVNs are requested.
