Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Powertrain Calibration Information
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 line |
| 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 - US federal |
| 7 | Revision level (will advance as revisions occur), not printed on label but may be 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
