Is Your Cadillac SRX Running Erratically? The ECM Might Be the Culprit.
If your 2010-2011 Cadillac SRX is experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel mixture and ignition timing to transmission shifts and emissions control. When it begins to fail, it can create a cascade of problems that are difficult to diagnose and can leave your luxury SUV feeling unreliable.
From the Diagnostic Bay
We once had a 2011 SRX come into the shop with a classic case of “parts cannon” diagnostics. The owner had replaced two oxygen sensors and a mass airflow sensor trying to clear a persistent P0171 (System Too Lean) code. The vehicle ran rough and hesitated on acceleration. After hooking up our professional scan tool, we noticed the short-term fuel trims were erratic and unresponsive to throttle input. This pointed away from the sensors and towards the processor. We swapped in a correctly programmed ECM, performed a quick security relearn, and the fuel trims immediately stabilized. The SRX ran perfectly. It’s a classic reminder that the symptoms often point to sensors, but the brain controlling them is the real source of the problem.
The Direct-Fit Solution: A Pre-Programmed 2010-2011 SRX ECM
Don’t let a faulty computer keep you off the road. This genuine GM Engine Control Module, part number 12637106, is the definitive solution for your vehicle. What sets our service apart is the critical programming we perform before shipping. When you order, you provide us with your vehicle’s 17-digit VIN. Our technicians then use official GM equipment to flash the module with the latest factory software specific to your SRX. This ensures that the ECM communicates perfectly with your engine, transmission, and all other onboard systems, restoring the performance and reliability you expect from a Cadillac.
Common Symptoms of a Failing ECM:
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Rough or erratic idling and poor engine performance.
- ✔ Difficulty starting the vehicle or a complete no-start condition.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Automatic transmission shifting issues or harsh shifts.
Why VIN Programming is Essential
An ECM is not a one-size-fits-all part. Each module must be calibrated for a specific vehicle’s engine, transmission, and options package. Simply installing a used or unprogrammed module will result in a no-start condition and can even cause damage to other electronic components. Our VIN programming service eliminates the need for an expensive trip to the dealership for flashing. Your new 2010-2011 SRX ECM arrives ready for installation, saving you time, money, and hassle. In most cases, a simple security relearn procedure (which can be done without special tools) is all that’s needed to get you back on the road.
Broad Compatibility Beyond the SRX
While this is the primary ECM for the 2010-2011 Cadillac SRX with the 3.0L engine, this versatile module (part number 12637106 and its interchanges) is also a direct fit for a wide range of other GM vehicles.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software for your specific vehicle.
What is a VIN and where do I find it?
VIN stands for Vehicle Identification Number. It’s a unique 17-digit code for your car. You can typically find it on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is any additional procedure required after installation?
In many cases, you will need to perform a security relearn procedure, also known as a Passlock or anti-theft relearn. This procedure syncs the new ECM with your vehicle’s anti-theft system and can usually be done in your driveway without any special tools. Instructions are widely available online or in your vehicle’s service manual.
Where is the ECM located on my 2010-2011 Cadillac SRX?
On the 2010-2011 SRX, the Engine Control Module is typically located in the left-hand (driver’s side) engine compartment. Always disconnect the battery before attempting to remove or install any electronic components.
How do I provide my VIN?
You can add your 17-digit VIN to the notes section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the VIN before we begin the programming process.
