\n Quick Answer<\/span><\/p>\n

Remanufactured ECMs are recycled, repaired, and reprogrammed with the latest OEM software<\/strong> \u2014 performing identically to brand-new units at a fraction of the cost. They’re matched to your VIN for true plug-and-play installation. Find a remanufactured ECM for your vehicle<\/a>.<\/p>\n<\/div>\n

Electronic (also called engine) control modules are highly advanced pieces of technology \u2014\u00a0are computers that control, monitor, and regulate all the vital functions of your engine. From gear shifting to fuel injection, to the engine starting and fuel economy, the ECM is constantly making changes and adjustments to your engine to produce peak performance under varying conditions.<\/p>\n

What is a Remanufactured ECM?<\/h2>\n

Remanufactured engine control modules (ECMs) are car computers that have been repaired, refurbished, reprogrammed, and are good as new. In fact, because they contain all the latest manufacturer software updates, they are on par with ECMs in new vehicles that are rolling fresh off the line.<\/p>\n

Remanufactured ECMs are computers that have been recycled from a previous vehicle and programmed to work with a new one. Here\u2019s a look at the remanufacturing process for a recycled engine control module:<\/p>\n

    \n
  1. Finding a Suitable ECM to Reuse<\/strong> \u2013 Quality ECMs are obtained from a variety of sources, including auction vehicles or cars that just don\u2019t need them anymore. Examples include vehicles that can\u2019t be driven due to frame damage or insurance losses.<\/li>\n
  2. Examining and Testing the ECM<\/strong> \u2013 Once a quality ECM is found, the next step in the remanufacturing process is to make sure the hardware is all functioning properly. This involves visually inspecting the module for any signs of damage, and testing the circuits to make sure information and electricity can both run smoothly.<\/li>\n
  3. 3<\/strong>. Clean the Slate<\/strong> \u2013 Once the ECM is found, inspected, and determined to be in top working order, the next step in the process is to wipe it clean of all its previous software and data. Think of this as the same as if you buy a used laptop. All the files and software from the last owner are removed and you start fresh as if it is a new computer.<\/li>\n
  4. Upload the Latest Software<\/strong> \u2013 After the ECM is wiped clean of all previous data, it comes time to add the new software. This is where the remanufacturing process gets interesting. By matching the software with your vehicle\u2019s make, model, year, and VIN<\/a>, your ECM is able to get the latest and best OEM software and data right from the manufacturer. This means your car computer will have all the updates and information as the ones in brand new vehicles. Plus, because it is matched with your car\u2019s VIN number, it is tailored to work with your specific vehicle and allow it to function at its optimal level.<\/li>\n
  5. The Cycle Repeats<\/strong> \u2013 Once you receive your remanufactured and reprogrammed ECM, then you send in your malfunctioning or out of date module so it can be determined to be viable for reuse or not. This is where a core charge comes in\u2014a sort of deposit you pay when purchasing an ECM that you\u2019ll get back once you turn in your previous one.<\/li>\n<\/ol>\n

    And that\u2019s about it. Pretty simple right?<\/p>\n

    If you\u2019re looking to replace your ECM then all you have to do is put in your car\u2019s info (make, model, year, VIN)<\/a>, order the module, and send in your current engine module. All the wiping, reprogramming, flashing, and testing is done for you!<\/p>\n","protected":false},"excerpt":{"rendered":"
