So in the case that this part is out of stock, you may check the following which are 100% compatible.:






This ECM has been refurbished and programmed with the latest calibration version available for these units directly from Toyota.




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 with your keys. No programming needed.




When you order, at checkout we provide a form for you to enter your vehicle’s VIN so we can program it in the ECM before it is shipped to you.


If you do not provide your vehicle’s VIN in the provided order form or in an email within 24 hours after placing the order, we will ship the ECM without the VIN number. In this condition, the car will still start and function as normal, but check engine light will be lit for the “VIN Mismatch” error code.


Please, be accurate when entering the VIN. The VIN must have 17 alphanumeric characters. If you provide wrong or mistaken VIN, please contact us with the correct number within 24 hours after the order is placed. Otherwise, we cannot be held liable for programming no VIN, or the incorrect VIN.


We understand that mistakes do happen. So if you send the wrong VIN or do not provide it, maybe you forgot to do so, you may send back the ECM and let us know the VIN so we can program it in the ECM. In this case, the service will not be charged, but the exact shipping expenses determined by USPS or FedEx (your choice) will need to be charged.




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 or the VIN is entered, and neither they are programmed to start your car. 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.
