Restore Peak Performance to Your Vehicle’s Engine
Is your 2010-2011 Cadillac SRX, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that governs your vehicle’s engine performance, fuel economy, and emissions. A faulty ECM can disrupt communication between critical sensors and systems, leading to frustrating and often misdiagnosed problems. This replacement Engine Control Module, part number 12630908, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We once had a 2011 Equinox in the shop with a laundry list of issues: erratic shifting, poor fuel mileage, and a check engine light that multiple shops couldn’t solve. The owner had already replaced the MAP sensor, two oxygen sensors, and the throttle body based on generic code readings. The problems persisted. When we hooked up our professional scan tool, we noticed the live data stream from the ECM was lagging and occasionally dropping out. The computer itself was the source of the phantom codes. We installed a VIN-programmed ECM just like this one, performed the security relearn, and the vehicle ran perfectly. It’s a powerful reminder that the ECM is the foundation of the entire engine management system, and when it fails, it can create a cascade of misleading symptoms.
Is Your Vehicle Showing Signs of ECM Failure?
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns with various codes.
- ✔ Noticeable decrease in fuel economy for no apparent reason.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or inconsistent idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Transmission shifting issues or harsh engagement.
- ✔ Communication errors with diagnostic scan tools.
Why Choose Our Programmed 2010-2011 SRX Engine Control Module?
Don’t settle for a generic, unprogrammed module that requires an expensive trip to the dealership for flashing. Our service is designed to provide a seamless, straightforward repair. When you purchase this ECM, we take care of the critical programming for you. Simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN) during or after checkout. Our technicians will then flash the module with the latest, most up-to-date GM-certified software specific to your exact vehicle. This ensures perfect compatibility with your engine, transmission, and all related electronic systems. This VIN-matching process is what makes our module a true plug-and-play solution, eliminating the common headaches associated with computer replacement.
Simple Installation Process
Replacing the ECM is a manageable task for the experienced DIYer or any professional mechanic. On most compatible vehicles like the 2010-2011 SRX, Equinox, and Terrain, the module is located in the LH (driver’s side) engine compartment. After disconnecting the battery, you simply unbolt the old module, disconnect the wiring harnesses, and install the new one. Once installed, you will likely need to perform a simple security relearn procedure (often called a Passlock or anti-theft relearn), which pairs the new ECM to your vehicle’s keys. This procedure typically takes 10-30 minutes and does not require any special tools. Instructions for this process are widely available online or in service manuals.
Guaranteed Compatibility
This ECM is a direct replacement for a wide range of General Motors vehicles and interchanges with multiple part numbers, including 12616889, 12630908, 12637106, 12642665, 12650256, and 12651993. While it is the primary fit for the 2010-2011 SRX Engine Control Module, it also fits models like the Buick Allure/LaCrosse, Cadillac CTS, Chevrolet Camaro/Captiva/Equinox/Impala/Orlando, GMC Terrain, and Saab 9-5. Please verify your original part number or consult the detailed fitment list to ensure this is the correct component for your vehicle.
Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming involves loading your vehicle’s specific software and calibration files onto the ECM. This ensures the computer knows your engine size, transmission type, tire size, and other factory options. Without it, the vehicle may not start, run poorly, or have warning lights. We handle this for you before shipping.
Do I need to do anything after I install this ECM?
Yes, after installation, you will need to perform a security relearn procedure. This syncs the new ECM with your vehicle’s anti-theft system and keys. It’s a simple procedure that usually involves turning the key on and off in a specific sequence and does not require a scan tool.
Is this part truly plug-and-play?
Because we program it to your VIN, it’s as close to plug-and-play as possible. The only additional step is the security relearn. You will not need to take your vehicle to a dealer for expensive programming after installation.
How do I provide my VIN?
You can add your 17-digit VIN in the notes section during checkout or send it to us in a message after you place your order. We cannot ship the module until we have your VIN to program it correctly.
How can I be sure this fits my vehicle?
The best way is to match the part number from your original ECM to one of the numbers listed: 12616889, 12630908, 12637106, 12642665, 12650256, or 12651993. If you are unsure, please send us your VIN, and we can verify compatibility for you.
