  • Use an OBD-II scanner: You can also use an OBD-II (On-Board Diagnostic) scanner to read the check engine light codes. These scanners are designed to be plugged into the vehicle’s diagnostic port and can read the codes stored in the vehicle’s computer. They are widely available at auto parts stores and are relatively inexpensive.
  • Check the dashboard lights: Some vehicles may also display the check engine light codes on the dashboard using a series of flashing lights or symbols. In this case, you can try to decode the codes by counting the number of flashes or by looking for specific patterns in the flashing lights.

Regardless of which method you choose, it is important to remember that the check engine light codes are only a starting point in diagnosing the problem with your 2019 Dodge RAM. You will still need to have the vehicle properly diagnosed and repaired by a mechanic or dealership to fix the issue and turn off the check engine light.
