Is Your 2017 Enclave Running Rough or Showing a Check Engine Light?
If you’re dealing with frustrating issues like unpredictable stalling, poor fuel economy, a persistent check engine light, or even a no-start condition, a failing Engine Control Module (ECM) is often the culprit. As the brain of your vehicle’s engine, when the ECM falters, it can cause a cascade of performance problems that can be difficult to diagnose. You need a solution that is reliable, straightforward, and gets you back on the road without the hassle and expense of a dealership visit.
This is a direct-fit replacement Engine Control Module for your 2017 Buick Enclave. We take the guesswork out of the repair by pre-programming the unit specifically for your vehicle using your VIN. This ensures that it arrives ready for installation with the latest, most stable software updates from GM.
Expert Pro Tip: Check for Contamination Before Installation
In my 20+ years in the shop, I’ve seen countless ECM replacements. One simple step that prevents future headaches is to meticulously inspect and clean the wiring harness connectors before plugging in the new module. On vehicles like the Enclave where the ECM is mounted behind the fan shroud, it’s exposed to moisture and road grime. Use a quality electronics cleaner and a small nylon brush to remove any corrosion or debris from the pins. A clean connection is critical for the ECM to communicate properly with all vehicle sensors.

Simple, Straightforward Installation Guide
Replacing the ECM on your Enclave is a manageable job for a DIYer with basic tools. The module is typically located behind the engine’s cooling fan shroud.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all systems to power down.
- Locate the ECM: On the 2017 Enclave, the ECM is mounted to a bracket behind the radiator fan shroud. You may need to remove a plastic cover for access.
- Disconnect Wiring: Carefully release the locking tabs on the electrical connectors and pull them straight off the module. Never pull by the wires themselves.
- Remove the Old Module: Unbolt the ECM from its mounting bracket. Note the orientation of the old module before removing it.
- Install the New ECM: Mount your new, pre-programmed ECM onto the bracket and secure the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal.
- Final Step: Your vehicle may require a security relearn procedure, which can typically be done by cycling the key. Instructions will be provided if necessary.
