Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This ECM will arrive at your door fully programmed to the VIN you provide. The only thing you need to do is install it. In some cases, a CASE relearn or security relearn may be required, which can be done with a capable scan tool or by following a simple key-cycle procedure.
Where and when do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this a new part?
No, this is a thoroughly inspected and tested used OEM part sourced from a salvaged vehicle. This allows us to provide a reliable, factory-correct part at an excellent value.
How do I know if this will fit my vehicle?
Please check the compatibility list provided in this listing. The most important step is to match your original ECM’s service number to one of the compatible numbers listed (12581144, 12588472, 12592124, 19260507). If you are unsure, please contact us with your VIN before ordering.

This unit is backed by our one-year replacement warranty. This gives you peace of mind that you are receiving a quality, tested part.
Will this Programmed 12592124 ECM fix my exact problem?
This module is the direct solution for a failed ECM. However, it’s crucial that your vehicle has been properly diagnosed. This part will not fix issues related to other faulty components like sensors, wiring, or fuel system parts. A correct diagnosis is the key to a successful repair.
