Hi there:

In most newer trucks, like your 2014 Ram, if an error light is triggered and the repairs are made, you’ll have to clear those stored error codes in the ECU with a digital scanner or they will stay illuminated. If you have access to this equipment, you can do it yourself. However, if not, contact a professional local mechanic and ask them to complete a check engine light inspection. This will allow them to verify there are no further issues and clear those stored codes.
