Restore Your Cadillac’s Peak Performance
Is your 2010-2012 Cadillac CTS plagued by a persistent Check Engine Light, rough idling, poor fuel economy, or frustrating stalling issues? These are classic signs that the very brain of your engine—the Engine Control Module (ECM)—is failing. Don’t let a faulty computer compromise the sophisticated performance and reliability you expect from your Cadillac. This is your direct, hassle-free solution to restore your vehicle’s engine to perfect factory specifications.
Common Symptoms of a Failing ECM & Your Direct Solution
A failing ECM can cause a wide range of confusing and intermittent problems. If you’re experiencing any of the following, this pre-programmed module is the definitive fix you need:
- Unexplained Check Engine Light (CEL) activation
- Diagnostic Trouble Codes (DTCs) related to internal module failure (e.g., P0601, P0606)
- Poor or erratic automatic transmission shifting
- Engine stalling, hesitation, or misfiring
- A complete no-start condition where the engine cranks but won’t turn over
- Noticeable decrease in fuel efficiency
- Communication errors with diagnostic scan tools
Instead of paying for expensive diagnostics and programming fees at a dealership, you can solve the problem yourself. We provide a professionally programmed 2010-2012 Cadillac CTS ECM 12637106 that is ready for installation right out of the box.

Expert Insight: From Code to Confidence
We recently worked with a 2011 CTS owner who was chasing a ghost. His car would intermittently refuse to start and threw a P0601 ‘Internal Control Module Memory Check Sum Error’ code that his local shop couldn’t solve. They suggested a new module from the dealer for over $1,200. He ordered our pre-programmed 2010-2012 Cadillac CTS ECM 12637106 instead. After a 15-minute installation and a quick security relearn, the car started flawlessly. The code vanished, and the owner had his premium driving experience back for a fraction of the cost. This isn’t just a part; it’s a permanent solution.
Frequently Asked Questions
Do I need to do any additional programming?
No. This ECM comes fully programmed to your vehicle’s VIN. The only step you may need to perform is a security relearn procedure (also known as a key relearn or anti-theft relearn), which can typically be done in your driveway in about 30 minutes without any special tools. We can provide instructions for this simple process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.

Yes. This ECM is a direct replacement for multiple part numbers, including 12616889, 12630908, 12637106, 12642665, 12650256, and 12651993. As long as your vehicle is listed in the compatibility chart, this module will work perfectly.
What is the warranty on this ECM?
This unit is backed by our one-year replacement warranty. This gives you confidence and protection for your purchase.
Is this a guaranteed fix for my car’s problems?
While this 2010-2012 Cadillac CTS ECM 12637106 is the solution for the symptoms listed, it’s crucial that your vehicle has been properly diagnosed. We recommend confirming with a qualified mechanic that the ECM is the point of failure before ordering to ensure this part resolves your issue.
