Restore Peak Performance to Your Vehicle with a Programmed 2017 Verano ECM
The Engine Control Module (ECM), often called the vehicle’s brain, is the central command center for your engine’s performance, fuel efficiency, and emissions. When it begins to fail, it can trigger a wide range of confusing and frustrating issues, from a simple check engine light to a complete no-start condition. This replacement ECM, part number 12667002, is the definitive solution for restoring your vehicle’s factory operation and reliability. It arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN).
From the Diagnostic Bay
We once had a 2017 Impala come in with what the owner was convinced was a failing transmission. It was shifting harshly, hesitating between gears, and occasionally felt like it was slipping. They had already received a quote for thousands of dollars for a transmission rebuild. However, our diagnostic process showed no fault codes from the Transmission Control Module (TCM). Instead, we found intermittent communication errors from the ECM. The failing engine computer was sending corrupt data to the TCM, causing the erratic shifting. We installed a VIN-programmed ECM, and the ‘transmission’ problem vanished completely. It’s a classic case of how a faulty ECM can masquerade as a much more expensive mechanical failure.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Vehicle entering ‘limp mode’ with reduced power.
- ✔ Complete no-start or intermittent starting problems.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
The Plug-and-Play Advantage
Don’t waste time and money at a dealership for programming. We handle the critical software flashing process for you before the part ever leaves our facility. Simply provide us with your vehicle’s VIN during checkout, and our technicians will load the correct, updated software for your specific vehicle. This ensures a seamless installation process. While many installations are straightforward, some GM vehicles may require a simple security relearn procedure (often called a key relearn) after installation, which can typically be performed in your driveway without any special tools.
