Is Your Buick Regal Experiencing Frustrating Engine Problems?
If your 2011 Buick Regal is suffering from issues like poor performance, erratic shifting, a persistent Check Engine Light, or even a no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, managing everything from fuel injection and ignition timing to transmission function and emissions. When it fails, the entire system can become unreliable. Don’t let a faulty computer keep you off the road. This direct-fit, VIN-programmed Engine Control Module is the definitive solution to restore your vehicle’s performance and reliability.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to install with the latest GM software for your car.
What is a security relearn procedure?
After installation, you may need to perform a simple security relearn, also known as a key relearn. This procedure syncs the new ECM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes and can be done without any special tools. Instructions are readily available online for your specific model.
How do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Will this part fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s always best to have your vehicle scanned for diagnostic trouble codes (DTCs) to confirm the ECM is the source of the problem before ordering.
Is this a difficult part to install?
The ECM is typically located in the engine compartment (on the LH side for the Regal). Installation involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The physical replacement is straightforward for someone with basic mechanical skills. The most critical step is ensuring the battery is disconnected to prevent electrical damage.
