Is Your Buick Encore Running Rough, Stalling, or Showing a Check Engine Light?
If you’re dealing with frustrating engine problems like poor acceleration, erratic shifting, or a persistent check engine light, a failing Engine Control Module (ECM) is often the culprit. As the brain of your vehicle, the ECM controls everything from fuel mixture and ignition timing to transmission shifting. When it fails, it can bring your entire vehicle to a halt. In my 20+ years as a technician, I’ve seen how a faulty ECM can mimic a dozen other problems, leading to expensive and incorrect repairs. This module is the direct, reliable solution to get your 2013-2016 Encore performing like new again.

Expert Diagnosis for Your 2013-2016 Encore ECM
A customer’s 2015 Encore came into my shop last week with the check engine light on and a complaint of intermittent stalling at red lights. The scan tool showed a P0601 (Internal Control Module Memory Check Sum Error) and a few random communication codes. After verifying the battery and charging system were healthyโa critical first stepโwe confirmed the ECM itself was failing internally. Swapping in a VIN-programmed module like this one resolved all the issues. The customer was back on the road in less than an hour, without the long wait and high cost of a dealership repair. This is the exact fix for those hard-to-diagnose electronic gremlins.
Plug-and-Play Installation: Get Back on the Road Fast
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10 minutes for the systems to discharge.
- Locate the ECM: On the 2013-2016 Encore, the ECM is typically located in the engine compartment. Consult your owner’s manual for the exact position.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small flathead screwdriver to release the locking tabs if necessary. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Final Steps: Reconnect the negative battery terminal. Your vehicle may need to complete a drive cycle for all systems to recalibrate, but no additional programming is required.
Expert Pro Tip From a 20-Year Tech:
Before installing your new ECM, take a moment to inspect the electrical connector pins on the vehicle’s wiring harness. Look for any signs of corrosion (green or white powder) or bent pins. A poor connection is a common cause of ECM failure. Use a dedicated electronics cleaner and a small brush to gently clean the terminals to ensure a perfect connection and protect your new investment.
