DFM was primarily introduced in the 2019 Silverado 1500 models with certain engines. If your Silverado is a 2019 or newer, check if it has the 5.3L or 6.2L V8 engine, as those are often equipped with DFM.

3. VIN Lookup

You can run your Vehicle Identification Number (VIN) through an online database or your local dealership. This will give you extensive details about the specific features and configurations of your vehicle.

4. Community Discussions

Sometimes the best answers come from fellow Silverado owners. Check out forums or online communities dedicated to Chevrolet Silverado discussions. Many users share their own experiences and insights regarding DFM and how to confirm its presence.
