Is Your Cadillac’s Brain on the Fritz?
Is your 2010-2011 Cadillac CTS, or another compatible GM vehicle, suffering from perplexing issues like poor fuel economy, intermittent stalling, a persistent check engine light, or a complete no-start condition? These are classic signs that the very core of your vehicle’s management system—the Engine Control Module (ECM)—may be failing. The ECM is the central computer responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it falters, the entire vehicle’s performance and reliability are compromised.
Don’t let a faulty computer keep your car off the road. This direct-fit Engine Control Module, part number 19300015, is the definitive solution to restore your vehicle’s factory performance and operational integrity. We take the guesswork and hassle out of the replacement process by professionally programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ever leaves our facility. This ensures seamless communication with all other onboard systems, just as the original did.
From the Diagnostic Bay
We recently had a 2011 Buick Enclave come into the shop with a complaint of random misfires and a transmission that seemed to shift harshly at odd times. The owner had already replaced spark plugs, coils, and even a MAP sensor at another shop, but the problems persisted. After hooking up our professional scan tool, we noticed erratic data readings from the ECM. Instead of just throwing more parts at it, we tested the circuits and confirmed the module itself was the culprit. We installed a VIN-programmed ECM just like this one, and the Enclave immediately ran like it just rolled off the showroom floor. It’s a powerful reminder that sometimes the issue lies with the conductor of the orchestra, not the individual instruments.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication or sensor circuits.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly time spark or fuel delivery, leading to rough running.
- ✔ Poor Performance & Fuel Economy: Inaccurate calculations for the air-fuel mixture can drastically reduce power and efficiency.
- ✔ No-Start Condition: A completely failed ECM can prevent the fuel pump or ignition system from activating, leaving you stranded.
- ✔ Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh or erratic gear changes.
- ✔ Intermittent Electrical Issues: Seemingly unrelated problems can sometimes be traced back to a failing central computer.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), also known as the Engine Control Unit (ECU), is your vehicle’s main computer. It controls and monitors the engine’s performance, emissions, and other critical functions to ensure optimal operation.
Is this ECM ready to install when I receive it?
Yes, for most vehicles. We program the module with the latest GM software using the VIN you provide. This makes it a plug-and-play installation for the majority of compatible models. For the Camaro and LaCrosse, an extra step involving your old module is required for immobilizer programming.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) contains specific information about your car’s engine, transmission, emissions system, and other options. Programming the ECM with your VIN ensures it has the correct software to work perfectly with your exact vehicle configuration.
What if I have a Camaro or LaCrosse?
Due to the specific anti-theft (immobilizer) systems in the 2010-2011 Camaro and LaCrosse, we need to read the data from your original ECM. After you purchase, we will contact you with simple instructions for sending your old module to us so we can make the new one fully compatible.
Will this fix my check engine light?
If the check engine light is on due to a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to have your vehicle properly diagnosed to ensure the ECM is the root cause and not a separate sensor or wiring problem.
How can I be sure this is the right part?
Please check the part numbers listed (19300015, 19300014, 12617230, 12636355, 12635019) against your original module. You can also verify your vehicle’s make, model, year, and engine size against our compatibility list. If you’re still unsure, feel free to contact us with your VIN.
