End Your Engine Troubles with a VIN-Programmed ECM
Is your vehicle plagued by a persistent check engine light, erratic performance, or a frustrating no-start condition? A failing Engine Control Module (ECM) is often the culprit, acting as the brain of your engine. This isn’t just an inconvenience; it affects fuel economy, emissions, and overall drivability. We offer a direct, reliable solution: a high-quality replacement ECM, part number 12651994, that arrives at your door fully programmed to your vehicle’s specific VIN.

An Expert’s Note: We recently helped a customer with a 2012 GMC Acadia that was completely dead in their driveway. The local shop suspected the ECM but couldn’t program a new one. They ordered our Programmed 12651994 ECM, provided the VIN, and had the part in two days. Within an hour of installation, the family SUV was running perfectly again. This is the power of a VIN-specific, pre-programmed module—it turns a complex electronic repair into a simple component swap, getting you back on the road with confidence.

No dealership programming is needed. However, on most GM vehicles, you will need to perform a simple security relearn procedure, also known as the Passlock or anti-theft relearn.
