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.
| 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), not printed on label. Obtained through scan tool |
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.
