To clear a diagnostic trouble code (DTC) on a 2015 Ram 1500, you can follow these steps using an OBD-II scanner:
-
Connect the OBD-II Scanner:
- Locate the OBD-II port under the dashboard, near the driver’s side footwell.
- Plug the OBD-II scanner into this port.
-
Turn on the Ignition:
- Turn the ignition key to the "ON" position without starting the engine. This powers up the vehicle's systems and allows the scanner to communicate with the PCM (Powertrain Control Module).
-
Access the Scanner Menu:
- Use the scanner to navigate to the "Read Codes" or "Diagnostic" menu. This will show you the current trouble codes stored in the PCM.
-
Clear the Codes:
- Once you've reviewed the codes, select the option to "Clear Codes" or "Erase Codes" on the scanner. This will reset the PCM and clear the stored trouble codes.
- Wait for the scanner to confirm that the codes have been cleared.
-
Turn Off the Ignition and Disconnect the Scanner:
- Turn off the ignition and unplug the OBD-II scanner from the port.
-
Start the Engine:
- Start the engine to see if the check engine light has turned off. If the issue that triggered the code has been resolved, the light should stay off.
Important Note: Clearing the code does not fix the underlying issue that caused it. If the problem persists, the code will likely reappear. It’s essential to diagnose and repair the root cause before clearing codes to prevent potential damage to the vehicle.
For more detailed instructions specific to your Ram 1500’s configuration, including troubleshooting the cause of the codes, consulting a repair manual is highly recommended. The manual will guide you through both the process of clearing codes and addressing the underlying issues properly.
