Frequently Asked Questions
Do I need to have this programmed by a dealer or mechanic?
Absolutely not. The main benefit of our service is that the module arrives fully programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, saving you hundreds of dollars in dealership programming fees.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN, as this is crucial for correct programming.
My original part number is different. Will this still work?
Yes. This module is a direct replacement for several part numbers, including 12589297, 12597121, 12603892, and 19210738. As long as your vehicle is listed in the compatibility chart, this module will function correctly.
Is any other procedure required after installation?
In many cases, no. However, some GM vehicles may require a simple, key-on/key-off security relearn procedure to sync the new ECM with the vehicle’s anti-theft system. This procedure does not require any special tools and instructions can be easily found online or in your owner’s manual.
What if this doesn’t fix my problem?
This module is guaranteed to fix any issues directly caused by a faulty ECM. However, it’s essential that your vehicle has been properly diagnosed. If your issues are caused by other components (like a bad sensor or wiring), replacing the ECM will not solve them. We recommend a thorough diagnosis before purchase.
