Frequently Asked Questions
Do I need to do anything after I install this ECM?
In most cases, you will need to perform a simple security relearn procedure, also known as a key relearn. This process can typically be done without special tools and involves a sequence of key turns. We can provide you with instructions for this straightforward procedure.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). You can also add it as a note to the seller during the checkout process. We cannot ship your part until we receive the VIN for programming.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the ECM (often indicated by codes like P0601 or P0606), then this part is the correct fix. However, it’s crucial to have your vehicle properly diagnosed first, as many other sensors or components can also trigger a check engine light.
Is this a brand new part?
This is a high-quality, fully tested replacement component that meets or exceeds original equipment specifications. It is professionally programmed and verified to ensure reliability and performance.
What if my original part number is different?
This ECM is a direct replacement for several part numbers. As long as your original part number is on our interchange list (12668866, 12668994, 12643636, 12663405, 12670335, 22819494, 12692200), this unit will function correctly in your vehicle once programmed to your VIN.
