Your auto mechanic’s diagnoses have determined that a control module is the culprit causing the issues you’ve experienced with your vehicle. You’re faced with having to purchase a Control Module. There are many options, how do you choose? To make an educated decision, you first need to know the differences.

Genuine, OEM, Aftermarket, Used, Remanufactured. What’s the difference?

  • Genuine: A Genuine part is the part that was originally put in your car when it was new. It comes with the car maker’s logo so you will think your car manufacturer made it. It was actually made by another company. These are the most expensive types of parts you can purchase mainly because you are paying for the logo.
  • OEM: OEM stands for Original Equipment Manufacturer. This part was built by the company that originally made it for the car company. It is the exact same part that came in the vehicle. It simply doesn’t have the car maker’s logo on it.
  • Aftermarket: Aftermarket parts are made by a company other than the original manufacturer. These parts are made to fit and perform as well as, and in some cases better than the original.
  • Used: A used control module is one that was likely pulled out a vehicle that was wrecked or had damage to one of its mechanical systems that ended up sending the car to the junkyard. It has been subjected to previous use on the vehicle and is not new. Nothing has been done to repair it or correct any problems it may have. Therefore, its useful life and degree of serviceability are unknown. Most used modules will be sold “as is,” meaning no return, no exchange, no refund!
  • Remanufactured: Remanufacturing is the rebuilding of a product to specifications of the original manufactured product using a combination of reused and new parts. It requires the repair or replacement of worn out or obsolete components. It is then tested to ensure it performs as well as a new part.
