Frequently Asked Questions
What do I need to do after I order?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN. We cannot program and ship your ECM without it. You can typically add this as a note during checkout or send it to us in a message referencing your order number.
What is a ‘theft relearn’ and will I need to do one?
The theft deterrent relearn (also known as a security relearn) syncs the new ECM with your vehicle’s anti-theft system and keys. In many cases, the vehicle will start and run without this step. However, if it does not start after installation, this procedure will be required. It must be performed by a technician with access to GM’s TIS2WEB programming system.
Is this a new part?
No, this is a genuine, used OEM part that was carefully removed from a salvaged vehicle. Each unit is inspected and tested before being programmed and shipped to you.
Will this ECM fix my check engine light?
If the check engine light is caused by an internal failure of your old ECM (common codes P0601-P0606), then this programmed 12669908 ECM is the correct solution. However, if the light is on for other reasons (e.g., a bad oxygen sensor), you will still need to repair those separate issues.
Are there any other ‘relearn’ procedures I need to know about?
Yes, depending on your vehicle, additional procedures like a crankshaft position variation relearn or injector flow rate programming may be necessary for optimal performance. These are standard procedures after an ECM replacement and are the responsibility of the installer.
