Is Your Captiva Sport Running Rough? The ECM Might Be the Culprit.
If your 2013, 2014, or 2015 Chevrolet Captiva Sport is experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or erratic engine behavior, a failing Engine Control Module (ECM) is a very likely cause. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions control. When it starts to fail, it can create a cascade of problems that are difficult to diagnose and can leave you stranded. Don’t let a faulty computer dictate your vehicle’s reliability. This genuine, used OEM ECM, part number 12644446, is the definitive solution to restore your vehicle’s performance and peace of mind.
Expert Pro Tip: Before replacing your ECM, always verify your vehicle’s battery health and check the main engine ground connections. A weak battery or a corroded ground strap can cause voltage issues that mimic the symptoms of a failing ECM. Cleaning the connection points and ensuring the battery is fully charged is a simple diagnostic step that can save you time and money.
The Right Solution: A Programmed 2013-2015 Captiva Sport ECM
Finding a replacement ECM is only half the battle. A module from another vehicle won’t work correctly unless it is properly programmed to your specific Captiva Sport.

What exactly does the ECM do in my Captiva Sport?
The Engine Control Module (ECM) is your vehicle’s main computer. It processes data from dozens of sensors to control critical engine functions like the air-fuel mixture, ignition timing, idle speed, and variable valve timing. A properly functioning ECM is essential for optimal performance, fuel economy, and emissions.

Will this part require any additional relearn procedures?
