This ECM has been refurbished and programmed. This ECM has the latest calibration version available for these units directly from Toyota, which is calibration ID #30236200, and NOT the outdated #30236100 that all other sellers are offering.




You probably have learned that used ECMs need to be programmed in order to start the engine and it is true, but NOT with this ECM. Instead of needing to spare time and money to go to a shop or dealer for programming your ECM in order to start the engine of your car, this ECM only needs to be installed and it will be ready to be used. This means that the internal immobilizer system has been reset to accept and register your car keys right away (a $59.00 service for free). Your keys will be detected by the ECM as soon as installed. It will automatically register each key used to start the engine in the first few minutes after installing the ECM. After the registration cycle ends, your car will ONLY start with the registered keys. Registering more keys in the future is also possible (up to a total of 8 keys) with simple instructions we can provide upon request.




Another issue is that the VIN number is stored in these ECMs and unfortunately, it gets erased by default when the ECM is reprogrammed. This is set to behave like that by the manufacturer and there is no way to override it. That means that your ECM will lack a VIN number until it is installed in your car and the VIN number entered with a scanner. If you do not enter the VIN number, your car will be 100% functional, but the check engine light will be lit (trouble code P0630). The code will be “VIN mismatch“, which means that the VIN number is not present. This issue can not be avoided. This same thing will happen if you buy a brand new ECM.


Entering the VIN number must only be done in the target vehicle where the ECM is to be installed. That is why we cannot do it from here. If we do it, it will automatically be erased as soon as the ECM is installed. Again, it is a routine programmed to behave like that by the manufacturer.


Since your car will be 100% functional, and entering the VIN number is NOT urgent, you may enter the VIN number at your convenience. Any shop or dealer with the proper scanner can do that and only takes around 5 minutes.




We offer quality items which are backed up with a great warranty. These ECMs are offered in many marketplaces, but they are not tested, nor its calibration is updated, and neither they are programmed to start your car. On top of that, the VIN number must also be programmed anyway. You will get the best value on these ECMs when you buy from us.




The part number of your ECM is located on the label at the top of the ECM as shown below.
