Restore Peak Performance to Your Vehicle with a VIN-Programmed ECM
Is your 2006 Saturn Relay or another compatible GM vehicle suffering from perplexing issues like a persistent check engine light, poor fuel economy, rough idling, or even a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the electronic brain of your vehicle. A faulty ECM can disrupt everything from engine timing and fuel delivery to transmission shifting, making your vehicle unreliable and frustrating to drive. This replacement Engine Control Module, part number 12607096, is the definitive solution to restore your vehicle’s factory performance and reliability.

Simply provide us with your VIN after purchase, and our technicians will handle the complex programming, so you can focus on the simple installation.
From the Diagnostic Bay
We had a 2008 Chevy Impala come into the shop with a bizarre set of symptoms. The owner complained of intermittent stalling at stoplights and a transmission that seemed to shift harshly for no reason. We checked for codes and found a few communication errors that didn’t point to a specific sensor. After hours of chasing wires and testing components, we decided to inspect the ECM. We found subtle signs of internal corrosion on the board. We installed a VIN-programmed module just like this one, and the car immediately ran like new. It’s a reminder that the ECM is the central hub, and when it fails, it can cause a cascade of confusing problems that a single part replacement can solve.

Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully programmed to your vehicle’s VIN. It is ready for installation right out of the box. You will need to provide your VIN at the time of purchase so we can flash the module correctly.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can typically find it on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, then yes, this part will resolve those issues. It’s crucial to properly diagnose the problem first, as other failing sensors or components can also trigger a check engine light.
Is a security relearn procedure required after installation?
In many cases, a simple security relearn procedure may be necessary for the vehicle to recognize the new ECM and start. This procedure is straightforward and can typically be done without special tools. Instructions are readily available online or in your vehicle’s service manual.
How do I know if this part fits my vehicle?
This module fits a wide variety of GM vehicles. The best way to confirm is to match your original part’s service number to one of the numbers listed (12590032, 12602044, etc.). Providing your VIN during checkout allows us to double-check and ensure perfect compatibility.
