Is Your Buick Verano Experiencing Frustrating Engine Problems?
If your 2017 Verano is suddenly stalling, running rough, refusing to start, or displaying a persistent Check Engine Light, a failing Engine Control Module (ECM) is a very likely culprit. As the brain of your vehicle, the ECM controls everything from fuel mixture and ignition timing to transmission shifting. When it fails, the symptoms can be confusing and widespread, often leading to incorrect and expensive repairs on other components.
I’ve been diagnosing these systems for over two decades, and I’ve seen firsthand how a faulty ECM can mimic other problems. Just last month, a customer brought in a 2017 Chevy Equinox—which uses this exact same computer—convinced his transmission was failing due to harsh shifting and intermittent power loss. After a quick diagnostic scan, we found codes pointing to erratic solenoid commands. The issue wasn’t the transmission at all; it was a failing driver circuit inside the original ECM. A new module solved everything.

Plug-and-Play Installation: Get Back on the Road Fast
Installing your replacement 2017 Verano ECM is a manageable job for a DIYer with basic tools. While the exact location can vary slightly, on the Verano, it’s typically found in the engine compartment on the driver’s side.
Expert Pro Tip: Before You Install
Before plugging in the new ECM, take a moment to inspect the electrical connector plugs. Use a small brush and electrical contact cleaner to remove any dirt, oil, or corrosion from the terminals. A poor connection is one of the leading causes of premature module failure and can cause intermittent issues that are incredibly difficult to diagnose. A clean connection ensures a solid, reliable repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for all systems to discharge.
- Locate the ECM: On your Verano, find the module in the LH (driver’s side) engine compartment. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully release the locking tabs on the electrical connectors and pull them straight off. Then, unbolt the mounting hardware holding the old ECM in place and remove it.
- Install the New Module: Mount the new ECM securely in place. Reconnect the electrical harnesses, ensuring they click and lock firmly into position.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple key-cycle security relearn procedure. Turn the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds. Repeat this process two more times for a total of three 10-minute cycles. On the fourth cycle, the vehicle should start and run normally. This syncs the new ECM with your vehicle’s anti-theft system.
