Frequently Asked Questions
Do I need to get this programmed?
No. The main benefit of our service is that this ECM arrives at your door fully programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, saving you the time and expense of a dealership visit.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically find your VIN 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 is caused by a faulty ECM, this part will resolve the issue. However, it’s crucial to ensure that all other potential problems (like faulty sensors or wiring) have been properly diagnosed and addressed. This module will fix ECM-specific codes, such as P0601 (Internal Control Module Memory Check Sum Error).
Is this compatible with other GM vehicles besides the Saturn Aura?
Yes. This ECM, part number 12630457, is interchangeable with many other GM service numbers and fits a wide variety of makes and models from Buick, Cadillac, Chevrolet, GMC, Pontiac, Saab, and more. Please carefully review the detailed fitment list on this page to ensure compatibility with your specific vehicle and options.
What if my original part number doesn’t match 12630457 exactly?
That’s okay. GM uses many different service numbers for the same functional part. This module is a direct replacement for all the numbers listed in the description, including 12590032, 12602044, 12603530, and others. As long as your vehicle is on the compatibility list, this part will work perfectly once programmed to your VIN.
What is an ECM and what does it do?
The Engine Control Module (ECM) is your vehicle’s main computer. It controls and monitors critical systems like fuel injection, ignition timing, emissions systems, and automatic transmission shifting to ensure the engine runs efficiently and smoothly.
