how do I reset the check engine light on my Ram 1500 DT (2019-Present)?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, wrench set
• Ensure the vehicle is parked on a flat surface with the engine off.

2. Use OBD-II Scanner

1. Connect the Scanner: Plug the OBD-II scanner into the diagnostic port, usually located under the dashboard near the driver's seat.
2. Turn on Ignition: Turn the vehicle's ignition to the "ON" position without starting the engine.
3. Select 'Read Codes': Follow the scanner’s instructions to read any stored error codes.
4. Clear Codes: If error codes are present and have been addressed, select the option to clear the codes. This will reset the check engine light.

3. Reconnect Battery (if applicable)

1. Disconnect Battery: If you opted to disconnect the battery, use a socket or wrench to remove the negative terminal.
2. Wait: Leave the battery disconnected for 10-15 minutes to allow the vehicle's computer to reset.
3. Reconnect Terminal: Reattach the negative battery terminal and tighten it securely.
