- Hesitation or Lack of Power during acceleration.
- Complete No-Start Condition where the engine cranks but won’t turn over.

Expert Insight: The Critical Role of VIN Programming
In a modern vehicle like your Cadillac, the ECM doesn’t work in isolation. It’s the conductor of an orchestra, constantly communicating with the Transmission Control Module (TCM), Anti-lock Brake System (ABS), and Body Control Module (BCM). Simply swapping a used, unprogrammed module is a recipe for disaster, leading to system conflicts, security lockouts, and a car that won’t start. Our professional VIN programming service ensures your new ECM is a perfect digital match, allowing all systems to communicate flawlessly from the moment of installation. This is why a properly programmed **2010-2011 Cadillac STS 3.6L ECM** is non-negotiable for a successful and lasting repair.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We need this to program the module specifically for your car before we ship it. We will contact you with instructions on how to send it to us.
Is this ECM really “plug and play”?
For the vast majority of compatible models listed (like the STS, CTS, Acadia, Enclave, Traverse), yes. Once programmed to your VIN, it’s a direct installation. However, for the Camaro and LaCrosse models, an additional step is required to sync the immobilizer (security) system. We will contact you with simple instructions if you purchase for one of these two vehicles.
Will this fix my car’s specific problem?
This module will correct any issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, we always recommend having a qualified mechanic perform a full diagnostic to confirm the ECM is the root cause before ordering.
Is this the correct 2010-2011 Cadillac STS 3.6L ECM for my car?
Yes, this part is the correct fit for the 2010-2011 Cadillac STS with the 3.6L engine. It also fits a wide range of other GM vehicles. Please check the compatibility list in the description to ensure it matches your make, model, and year.
What do all the compatible part numbers mean?
Manufacturers often update part numbers over time. The listed numbers (19300015, 19300014, 12617230, etc.) are all functionally identical and interchangeable. As long as your original module’s part number is on our list, this unit is the correct replacement.
