Restore Peak Performance to Your Cadillac SRX
Is your 2010-2011 Cadillac SRX suffering from perplexing issues like stalling, rough idling, poor fuel economy, or a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifts and emissions control. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose, leading to frustrating and expensive trips to the mechanic.
This replacement Engine Control Module, part number 12650256, is the definitive solution to restore your vehicle’s factory performance and reliability. We take the guesswork out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). This ensures seamless communication with all other onboard computers and sensors, eliminating compatibility issues and the need for costly dealership programming.
From the Diagnostic Bay
We had a 2011 SRX come in with a complaint of intermittent stalling at stoplights and a P0606 (ECM/PCM Processor Fault) code that would come and go. The owner had already replaced the spark plugs, ignition coils, and even the throttle body with no success. The symptoms were so random it was a real head-scratcher. After confirming all power and ground circuits to the ECM were solid, we connected a scope and saw erratic voltage signals from the module itself. We installed one of our VIN-programmed ECMs, and the vehicle immediately ran like new. The customer was thrilled to finally have a reliable vehicle again after months of chasing ghosts. It’s a classic case where the root cause was the central computer, not the components it controls.
Common Symptoms of a Failing 2010-2011 SRX Engine Module
- ✔ Check Engine Light is illuminated with various trouble codes (DTCs), especially those related to internal processor errors (e.g., P0601-P0606).
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained stalling or shutting off while driving.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or erratic engine idling.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Automatic transmission shifts harshly or at the wrong times.
- ✔ Inability to pass an emissions test.
A Simple, Plug-and-Play Solution
Replacing your ECM shouldn’t be complicated. Our process is designed for both professional technicians and savvy DIYers. Here’s how it works:
- Place Your Order: Purchase this module for your 2010-2011 SRX.
- Provide Your VIN: After your purchase, simply send us your vehicle’s 17-digit VIN. You can find this on your dashboard, driver’s side door jamb, or on your vehicle’s registration.
- We Program It: Our technicians will flash the module with the latest, most stable GM-certified software specific to your VIN. This ensures all factory settings and vehicle-specific parameters are correctly loaded.
- Install and Drive: Once you receive the module, installation is straightforward. Disconnect the battery, unplug the old ECM, plug in your new one, and reconnect the battery. In most cases, no additional security relearn or programming is required.
This module is a direct replacement for a wide range of GM part numbers, including 12616889, 12630908, 12637106, 12642665, 12650256, and 12651993, making it a versatile solution for many vehicles beyond the SRX, such as the CTS, Equinox, Terrain, Impala, and more. Please verify your part number or consult the fitment list to ensure compatibility.
Frequently Asked Questions
What information do you need from me to program the ECM?
We only need your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to load the exact software and calibrations your vehicle had when it left the factory, plus any subsequent GM updates.
Will I need to have this programmed by a dealer after I receive it?
No. This module arrives pre-programmed and ready for installation. It is a true plug-and-play solution, saving you the time and expense of a trip to the dealership.
Is a security relearn procedure required?
For most GM vehicles of this era, the security information is stored in the Body Control Module (BCM), not the ECM. Therefore, a security relearn is typically not necessary. The vehicle should start and run immediately after installation.
How do I find my original part number?
Your original part number is printed on a sticker on the case of your current ECM. While this module replaces several part numbers, matching it is the best way to confirm compatibility if you are unsure.
What if my problem isn’t fixed after installing this module?
While this ECM will solve issues directly caused by a faulty module, it cannot fix underlying mechanical or electrical problems (e.g., bad sensors, wiring shorts). We recommend proper vehicle diagnostics before ordering. However, you can be confident you are receiving a fully tested and correctly programmed component.
