Is Your Cadillac, Buick, or GMC Running Rough?
A failing Engine Control Module (ECM) can be the source of countless frustrating and hard-to-diagnose issues. If you’re experiencing a persistent check engine light, erratic engine behavior, poor fuel economy, or even a no-start condition, the very brain of your vehicle could be the culprit. Don’t let a faulty computer keep you sidelined. This is the direct, reliable solution to get your vehicle back on the road, running exactly as it should.
Common Failure Symptoms & Your Direct Solution
When an ECM begins to fail, it can manifest in various ways. You might be dealing with one or more of the following problems:
- Persistent Check Engine Light (CEL) with communication-related codes (e.g., U0100)

- Poor or inconsistent automatic transmission shifting

Expert Insight: The Critical ‘Digital Handshake’
“In modern vehicles like your CTS or Enclave, the ECM doesn’t just manage the engine—it constantly ‘talks’ to dozens of other modules, from the transmission and ABS to the instrument cluster and anti-theft system. We call this the ‘digital handshake.’ When you install a generic, un-programmed module, that handshake fails. It’s like putting a stranger in a room of old friends; they don’t know how to communicate. By programming the ECM to your specific VIN before we ship, we ensure it knows exactly how to greet and work with every other module in your car from the moment you plug it in. This is the secret to a successful, hassle-free repair.”
Take control of your repair and restore your vehicle with a reliable, expertly prepared component. This Programmed 2010-2011 Cadillac CTS ECM is your path to a smooth-running engine and renewed driving confidence.
Frequently Asked Questions
Do I need to do any programming myself?
For most listed vehicles (CTS, Acadia, Enclave, Traverse, etc.), no additional programming is required. The unit is ready for installation. For the Camaro and LaCrosse models, we will need your original ECM to transfer specific immobilizer data to make the new one plug & play. We will contact you with instructions if you purchase for one of these models.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email. We will not ship the part until we have the VIN to ensure perfect programming.
What if my original part number isn’t 12636355?
That’s okay. This ECM is a direct replacement for a range of part numbers, including 19300015, 19300014, 12617230, and 12635019. As long as your vehicle make, model, year, and engine are on our compatibility list, this module will work for you.
