Frequently Asked Questions
Do I need to do any programming after I receive it?
No. This ECM is pre-programmed to your vehicle’s VIN before we ship it. However, you will likely need to perform a simple security relearn procedure, which can typically be done in your driveway without any special tools. We can provide instructions for this process.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We will contact you with instructions on how to provide this information so we can program the module accurately.
Will this fix my check engine light?
If the check engine light and associated codes are being caused by a faulty ECM, this part will resolve the issue. It’s crucial to ensure your vehicle has been properly diagnosed before ordering, as other sensors or wiring issues can cause similar symptoms.
What if my original part number doesn’t match 12597883 exactly?
This module is a direct replacement for several service numbers, including 12578554, 12596771, 12597191, 12597883, and 19210071. As long as your original part number is on this list, this unit is the correct replacement.
Is a security relearn procedure difficult?
Not at all. For most GM vehicles of this era, the procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the new ECM to synchronize with your vehicle’s anti-theft system.
Does this fit vehicles other than the Envoy?
Yes, this ECM is compatible with a range of 2005 GM models equipped with the 5.3L V8, as well as the Corvette, GTO, and SSR. Please check the detailed fitment list on this page to confirm it matches your specific vehicle.
