Unique Calibration
The Emission/Corporate Average Fuel Economy/CO2 Compliance Department is responsible for assigning these calibration numbers. Unique identifications are assigned to cover similar vehicles to differentiate between tires, drive configurations, final drive ratios and other calibration-significant factors. These 2 characters are chosen by the analyst to provide identifiable information unique to each calibration. For example, using the number 2 to denote a 2- valve engine versus using the number 4 to denote a 4-valve engine provides an easily identifiable difference.
Powertrain Calibration Information
Note. Powertrain calibration information is limited to a maximum of 5 characters per line on the VC label. Because of this, calibration identification consisting of more than 5 characters will wrap to the second line on the VC label.
Powertrain calibration information is printed in the lower right corner of the VC label. Only the base calibration information is printed. Revision levels will not appear, however, they can be obtained through a scan tool using the most current software revision.
| Item | Description |
|---|---|
| 1 | Model year (year in which the calibration strategy was first introduced). |
| 2 | Vehicle code |
| 3 | Transmission code |
| 4 | Unique calibrations (designates different hardware to similar vehicles), example: tires or drive ratios |
| 5 | Fleet code (describes fleet to which the vehicle belongs), example: 6 - EVAP |
| 6 | Certification region (lead region where multiple regions are included in one calibration), example: A - U.S. federal |
| 7 | Revision level (will advance as revisions occur), obtained through scan tool |
