Is Your 2017 Enclave Running Rough? It Could Be The ECM.
As a technician with over two decades of experience under the hood, I’ve seen firsthand how a failing Engine Control Module (ECM) can turn a reliable vehicle into a source of constant frustration. If your 2017 Buick Enclave is experiencing baffling issues like random stalling, a persistent Check Engine Light, poor acceleration, or even a complete no-start condition, the ECM is a primary suspect. This isn’t just a simple component; it’s the brain of your engine, and when it falters, the symptoms can be widespread and confusing.

Forget about expensive dealership diagnostics and programming fees. We offer a direct, effective solution. This ECM, part number 12667189, is meticulously tested and prepared for your specific vehicle. The most critical part of the process is that we program it to your vehicle’s unique VIN before it ships.

Expert Pro Tip: Check Your Connectors First!
Before you condemn your old ECM, take a moment to inspect the electrical connectors that plug into it. Over the years, I’ve seen countless cases where corrosion or a bent pin was the real culprit. Disconnect the battery, unplug the ECM, and use a small flashlight to look for any green or white crusty buildup or damaged pins. Cleaning them with a dedicated electronics cleaner and a small brush can sometimes solve the problem and save you money. If the connectors are pristine and the problems persist, you can be more confident the module itself has failed.
Common Symptoms of a Failing 2017 Enclave ECM
A faulty engine computer can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- โ Unexplained Check Engine Light (with codes pointing to various sensor circuits)
- โ Engine stalling or shutting off while driving
- โ Difficulty starting the engine or a no-start condition
- โ Noticeable decrease in fuel economy
- โ Poor engine performance, hesitation, or misfires

Plug-and-Play Installation: No Dealer Visit Required
Installing your new ECM is a manageable DIY job that saves you time and money. For the 2017 Enclave, the ECM is typically located behind the fan shroud, making it accessible from the top of the engine bay.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- Locate the ECM: On your Enclave, find the module mounted behind the cooling fan shroud.
- Disconnect the Wiring: Carefully release the locking tabs on the electrical connectors and gently pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Secure your new, pre-programmed ECM onto the bracket and plug in the electrical connectors until they click firmly into place.
- Reconnect the Battery: Reattach the negative battery terminal. Your vehicle is now ready to start. No additional programming or security relearn procedures are required.
