Is Your Cadillac SRX Experiencing Engine Problems?
The Engine Control Module (ECM), often called the engine computer, is the central brain of your 2009 Cadillac SRX. It manages everything from fuel injection and ignition timing to transmission shifts and emissions control. When it begins to fail, it can cause a wide range of frustrating and often intermittent issues that can be difficult to diagnose. A faulty ECM can leave your vehicle unreliable, inefficient, or even completely inoperable. This replacement module is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2009 SRX come into the shop with a complaint of random stalling and a persistent Check Engine Light. The owner had already replaced the spark plugs and a couple of sensors with no luck. After hooking up our professional scan tool, we noticed erratic data from multiple sensors and communication errors between modules. This pointed directly to an internal failure in the ECM. Instead of a costly and time-consuming trip to the dealer, we installed one of our pre-programmed modules. The vehicle started right up, the codes were gone, and the engine ran smoother than it had in years. This is a common story, and a correctly programmed ECM is almost always the fix.
Symptoms of a Failing 2009 Cadillac SRX ECM
- ✔ Check Engine Light is on with various, often unrelated, trouble codes.
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel economy.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Poor acceleration and overall loss of engine power.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. This means it is ready for installation right out of the box, with no additional programming required.
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
What if I have an anti-theft system?
In most cases, our programming handles the security information. However, some GM vehicles may require a simple security relearn procedure after installation, which typically involves turning the key on and off in a specific sequence. Instructions can be easily found online or in your owner’s manual.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part. Each module is thoroughly inspected and then programmed with the latest software to ensure it meets or exceeds original factory performance.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty ECM. While the symptoms listed are common for ECM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause of your vehicle’s problems before ordering.
