VEHICLE INFO
The Vehicle Info function allows scan tool to request 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.
Vehicle Info function applies to model year 2000 and newer OBD II
compliant vehicles.
The Scan Tool cannot verify if data is correct for scanned vehicles.
Calibration Verification Numbers (CVNs) are calculated values
required by OBD II regulations.
The CVN calculation may take several minutes.
CVNs are reported to determine if emission-related calibrations have
been changed. Multiple CVNs may be reported for a control module.
In-Use Performance Tracking, tracks performance of key Readiness
Monitors.
The calculation may take several minutes first time CVNs are requested.
