Restore Peak Performance to Your Vehicle
Is your Chevrolet Captiva Sport, or another compatible GM vehicle, suffering from frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition?

This pre-programmed ECM, part number 12651994, is the direct, reliable solution to get your vehicle running smoothly and dependably again.

An Expert’s Note on Programming: With over two decades of hands-on diagnostics, I’ve seen countless drivers waste time with generic, un-programmed modules. The ECM is the central command center; it must be perfectly synced to your vehicle’s specific systems, which is all tied to the VIN. Our professional programming service bridges that gap, ensuring the ‘brain’ we send you is a perfect match for the ‘body’ of your car. This is why this pre-programmed 2012-2013 Captiva Sport ECM is the ideal solution for a successful, hassle-free repair.
