Is Your 2009 Cadillac SRX Running Rough or Not Starting?
A failing Engine Control Module (ECM) can be the source of countless frustrating and difficult-to-diagnose issues. As the central computer of your vehicle, the ECM is responsible for managing everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it starts to fail, it can manifest as poor engine performance, random warning lights, stalling, or even a complete no-start condition. Don’t let a faulty computer keep your luxury SUV off the road. This direct-fit replacement Engine Control Module, part number 12630464, is the definitive solution to restore your vehicle’s performance and reliability.
Symptoms of a Failing 2009 SRX Engine Module
If you’re experiencing any of the following issues, a faulty ECM could be the culprit. A proper diagnosis is always recommended, but these are the classic signs of a computer on its way out:
- ✔ Check Engine Light: The light may be on constantly or illuminate intermittently. You might see codes related to sensor circuits, processor faults, or communication errors.
- ✔ Engine Performance Problems: Noticeable loss of power, poor acceleration, rough idling, stuttering, or misfires.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s gas mileage can be caused by the ECM failing to properly regulate the air-fuel mixture.
- ✔ Intermittent Stalling: The engine may cut out unexpectedly while driving or when coming to a stop.
- ✔ No-Start Condition: The engine cranks but refuses to start. This can happen if the ECM is not properly controlling the fuel injectors or ignition coils.
- ✔ Transmission Shifting Issues: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifting. A failing ECM can cause hard shifts, delayed engagement, or getting stuck in one gear.

Frequently Asked Questions
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) is essential for us to program the ECM with the exact software and calibrations for your specific vehicle. This includes engine size, transmission type, and other factory options. This ensures a seamless installation and proper vehicle operation.
Is this ECM difficult to install?
The physical installation is typically straightforward. It involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and installing the new one in its place. However, after installation, you will likely need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn), which can usually be done without special tools. Instructions are widely available online.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this replacement part will resolve the issue. It’s crucial to have a proper diagnosis to confirm the ECM is the root cause and not a separate sensor or wiring problem.
