Is your 2006 Saturn Relay suffering from mysterious engine problems, a persistent check engine light, or erratic performance? The Engine Control Module (ECM), the central computer of your vehicle, is often the root cause. This direct-fit replacement ECM, part number 12630457, is the definitive solution to restore your vehicle’s factory performance and reliability. Unlike modules that require expensive dealership visits, this unit arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), loaded with the latest GM software updates. This ensures a seamless installation process and optimal engine function right out of the box.
From the Diagnostic Bay
We had a 2006 Saturn Relay come into the shop with a classic complaint: intermittent stalling at stoplights and a check engine light with codes for multiple sensor failures. The owner had already replaced the throttle position sensor and the mass airflow sensor with no improvement. After hooking up our professional scan tool, we saw that the sensor reference voltages were fluctuating wildly. This is a tell-tale sign not of faulty sensors, but of a failing computer that can’t provide a stable power supply. We installed a VIN-programmed ECM, cleared the codes, and the van ran perfectly. It’s a reminder that when multiple, unrelated codes appear simultaneously, it’s often wise to investigate the component they all report to: the ECM.
Common Symptoms of a Failing 2006 Saturn Relay ECM
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling or hesitation during acceleration
- ✔ Rough idling or inconsistent engine RPM
- ✔ A noticeable decrease in fuel economy
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Transmission shifting problems or harsh shifts
- ✔ Communication errors with diagnostic scan tools
The Plug-and-Play Advantage: VIN Programming Included
The biggest hurdle in replacing a modern vehicle’s computer is the complex programming required to sync it with your specific vehicle’s systems, including the anti-theft immobilizer. We eliminate this obstacle completely. When you purchase this module, you simply provide us with your VIN. Our technicians will then flash the unit with the correct software and calibration files directly from GM’s database. This means the 2006 Saturn Relay ECM you receive is tailored specifically for your van’s engine, transmission, and options package. This process not only saves you hundreds of dollars in dealership programming fees but also ensures your vehicle operates exactly as the manufacturer intended, with all the latest performance and drivability improvements.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. This ECM comes fully programmed to your vehicle’s VIN before it is shipped. It is ready for installation upon arrival, saving you time and the high cost of dealership programming.
Where is the ECM located on a 2006 Saturn Relay?
On the 2006 Saturn Relay, the Engine Control Module is typically located in the engine compartment on the driver’s side, often near the firewall or air filter housing. Always disconnect the vehicle’s battery before attempting removal or installation.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot ship the module until we have this information to ensure it is programmed correctly for your specific vehicle.
Is any other setup required after installation?
In some cases, a security relearn procedure may be necessary to sync the new ECM with your vehicle’s anti-theft system. This is a simple procedure that can typically be done without special tools and instructions can be provided.
What happens if I continue driving with a bad ECM?
Continuing to operate a vehicle with a failing ECM can lead to more severe problems, including poor fuel mileage, engine damage, catalytic converter failure, and leaving you stranded. It is crucial to address a faulty module promptly to ensure safety and prevent more costly repairs down the road.
