Since 1996, all new cars sold in the United States have been equipped with the OBD II diagnostic port that makes figuring out computer-related problems much simpler but for pre-96 Ram pickups, you can “pull” and read any computer codes with just your ignition key. Checking your own codes will allow you to figure out if there are any problems with the engine computer system in your Ram and if you have a check engine light – this trick will allow you to figure out why.
This “trick” actually works for the vast majority of modern cars, trucks and SUVs built prior to the OBD II era but this relates specifically for DodgeForum purposes to the early 2nd gen and all 1st gen Dodge Ram pickups. DF member Seal put together a brief yet comprehensive DIY of how to pull the codes in your pre-96 Ram truck complete with a list of applicable codes for 1st and 2nd gen Ram trucks – explaining how to pull the codes, how to read the codes and what each numeric code means.
