Is Your Cadillac or GM Vehicle Running Rough?
If you’re dealing with a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition on your Cadillac CTS, SRX, or Buick, a failing Engine Control Module (ECM) is often the culprit. In my 20+ years as a diagnostic technician, I’ve seen these symptoms countless times. Drivers often spend hundreds on new sensors and coils, only to discover the brain of the engine was the issue all along. This isn’t just a part; it’s the central command for your vehicle’s performance and efficiency.

Forget expensive dealership visits and the headache of finding a shop that can program a replacement module. We offer a straightforward solution. This is a thoroughly tested, used OEM Engine Control Module, part number 12592124, that comes pre-programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we’ll flash the module with the latest, most stable software updates directly from GM. When it arrives, it’s ready for installation.
A Technician’s Real-World Experience
“A customer’s 2006 Cadillac SRX with the 3.6L engine came into the shop last month. It had intermittent stalling and a random misfire code that would jump between cylinders. The owner had already replaced three ignition coils and all the spark plugs with no success. After hooking up the scope, we saw the injector pulse width was erratic. The issue wasn’t the injectors or coils; it was the driver circuit inside the original ECM failing under heat. We installed one of these VIN-programmed modules, and the SRX ran perfectly. It’s a classic case where chasing symptoms can be costly, while addressing the root cause is the true fix.”

Simple Plug-and-Play Installation Guide
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.

- Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be released. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Reconnect the wiring harnesses, ensuring they click securely into position.
- Reconnect and Start: Reconnect the negative battery terminal. Your vehicle is now ready to start. The security system will automatically relearn the new module.
