Restore Peak Performance to Your GM Vehicle
Is your 2012-2013 Chevrolet Captiva Sport, Cadillac CTS, or Buick LaCrosse suffering from mysterious and frustrating engine problems? Issues like a persistent check engine light, rough idling, stalling, or a complete failure to start can often be traced back to a single, critical component: the Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the entire system can be compromised, leaving you with an unreliable and inefficient vehicle.
This replacement ECM, identified by part numbers 12651994, 12643248, and 12652814, is the definitive solution to get your vehicle running like new again. We take the guesswork and high cost out of the repair process. Unlike a generic part from a local store, this module comes fully programmed to your specific vehicle using your VIN. This means it arrives ready for installation, with the latest GM software updates already loaded. You can bypass the expensive trip to the dealership for programming and get back on the road faster.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication, sensor circuits, or processor faults.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly time spark or fuel delivery, leading to rough running and stalling.
- ✔ Poor Fuel Economy: Incorrect air/fuel mixture calculations can cause your vehicle to consume significantly more gasoline.
- ✔ No-Start Condition: A completely failed ECM will not be able to activate the fuel pump or ignition system, preventing the engine from starting.
- ✔ Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh shifting or getting stuck in gear.
- ✔ Intermittent Electrical Issues: Seemingly random problems that come and go can sometimes be traced back to a failing internal processor in the module.
The Importance of a Programmed 2012-2013 Captiva Sport ECM
Modern vehicles are complex systems, and the ECM is tailored specifically to the vehicle it came from. It contains data for the engine size, transmission type, emissions equipment, and even the security system (anti-theft). Simply swapping a used module from another vehicle will not work; the vehicle will not start due to a VIN mismatch and security lockout. Our professional programming service ensures that the replacement ECM is a perfect digital match for your car. We flash it with the most current GM-approved software for your VIN, which can often resolve underlying drivability issues that were present even before the original module failed.
Simple, Hassle-Free Process
Ordering is straightforward. After you complete your purchase, simply provide us with your vehicle’s 17-digit VIN. Our technicians will handle the rest, programming the module to your exact specifications before shipping it out. This plug-and-play approach minimizes your vehicle’s downtime and eliminates the need for specialized diagnostic tools for programming.
Broad Compatibility Across the GM Lineup
While this is a perfect solution for the 2012-2013 Captiva Sport ECM, this module is also a direct replacement for a wide range of other GM vehicles. Please verify your original part number and check the comprehensive fitment list below to ensure compatibility with your specific make, model, and year. This unit fits models such as the Cadillac CTS, Chevrolet Impala, Buick LaCrosse, GMC Terrain, and many more, making it a versatile and reliable choice for many owners.
Frequently Asked Questions
Do I need to do 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 security relearn procedure, which can typically be done without special tools and takes only a few minutes. Instructions can be provided if necessary.
How do I provide my VIN?
After you place your order, you can send us a message with your 17-digit Vehicle Identification Number (VIN). You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Is this compatible with part number 12643248?
Yes. This ECM is a direct replacement for several part numbers, including 12651994, 12643248, and 12652814. As long as your original module carries one of these numbers, this unit will be a compatible replacement once programmed to your VIN.
What if I install it and my problem doesn’t go away?
While a faulty ECM is a common cause for the symptoms listed, proper vehicle diagnostics are essential. If the new module does not solve your issue, it’s likely the problem lies with another component, such as a sensor, wiring harness, or fuel pump. We guarantee our programming and the functionality of the module itself.
Where is the ECM located on a 2012 Captiva Sport?
On the 2012-2013 Chevrolet Captiva Sport, the Electronic Control Module (ECM) is typically located in the engine compartment on the driver’s side (LH), often near the air filter housing or firewall.
