Greetings all, I just got a 2014 Viking with 750 hours on it. I know nothing about what's been done to it prior to me getting it. I do know it recently had an oil change but I think that's it. The check engine light came on the first day I brought it home. Is there a way to "pull" a code out like on a regular car or what could be the causes of this light? Thanks for all y'all's help, I'm new to these and to here, I did search the forum but didn't find the light discussed. The speedometer is not registering either so I don't know if these two items are related or not.
