Restore Your Cadillac’s Peak Performance
Is your 2009 Cadillac SRX experiencing frustrating and unpredictable issues like stalling, rough idling, a no-start condition, or a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM). Your vehicle’s ECM is its brain, and when it falters, it can disrupt everything from fuel delivery to transmission shifting. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s reliability and your peace of mind. Put an end to the guesswork and get your luxury crossover running like new again with this professionally programmed engine computer.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer is the likely culprit:
- Check Engine Light: Often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606.
- No-Start or Hard-Start: The engine cranks but refuses to start, or takes an unusually long time to turn over.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.
- Erratic Shifting: The transmission may shift harshly, unpredictably, or get stuck in one gear.
- Stalling: The engine may shut off unexpectedly while driving or when coming to a stop.
This module is the definitive solution. We take the complexity out of the repair by pre-programming this Programmed 2009 Cadillac SRX ECM 12628911 specifically to your vehicle’s unique Vehicle Identification Number (VIN).

Expert Insight: The Critical Role of VIN Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners try to save a few dollars by installing a used, unprogrammed ECM from a salvage yard. This almost always leads to more problems. The ECM is tied to your vehicle’s security system, transmission, and specific engine options. Without correct VIN programming, the vehicle simply won’t start, or it will run in a reduced-power “limp mode.” Our service bridges that gap. By flashing the module with your VIN before it ships, we deliver a part that communicates seamlessly with your Cadillac’s entire electronic network, just as a new one from the factory would. This is the key to a successful, lasting repair.
Don’t let a faulty computer keep your Cadillac sidelined. Ordering this Programmed 2009 Cadillac SRX ECM 12628911 is the most reliable and efficient way to solve complex electronic issues and restore the dependable performance of your vehicle. Simply provide your VIN during checkout, and we’ll handle the rest. Your engine’s brain is just a few clicks away.
Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), also known as the engine computer, is the central processor for your vehicle’s engine. It controls critical functions like fuel injection, ignition timing, emissions systems, and transmission shifting to ensure optimal performance, fuel economy, and safety.
How do I provide my VIN for programming?
You can enter your 17-digit Vehicle Identification Number (VIN) during the checkout process. Please double-check it for accuracy, as this is essential for correct programming. Your VIN can be found on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Does this part require any additional programming after installation?
No. This ECM comes fully programmed to your vehicle’s VIN. In most cases, it is a direct plug-and-play installation. However, some vehicles may require a simple crankshaft position sensor relearn procedure, which can be performed with a compatible scan tool or by a qualified mechanic.
My original part number is not 12628911, but it’s on the list. Will this work?
Yes. The part numbers listed (like 12636659, 12639300, etc.) are interchangeable service numbers used by GM. As long as your vehicle’s year, make, model, and engine match the fitment list and your original part number is included in our cross-reference, this module is the correct, updated replacement for your vehicle.
Is this a difficult part to install?
The physical installation is typically straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. The location is noted in the fitment data (e.g., ‘LH engine compartment’). We always recommend professional installation if you are not comfortable performing the work yourself.
