Restore Peak Performance to Your GM 3.6L Engine
If you’re dealing with frustrating issues like stalling, a persistent check engine light, or erratic engine behavior in your 2010-2011 Buick Enclave or other compatible GM vehicle, a failing Engine Control Module (ECM) is often the culprit. As the brain of your engine, a faulty ECM can cause a cascade of problems that are difficult to diagnose. This replacement ECM, part number 19300014, is the definitive solution to get your vehicle running reliably again.
With over two decades of experience in automotive diagnostics, I’ve seen firsthand how a failing ECM can mimic other component failures, leading to wasted time and money on unnecessary parts. This module eliminates the guesswork. We take the hassle out of the replacement process by pre-programming the unit specifically for your vehicle using your VIN. This ensures it arrives with the latest GM software updates, ready for installation right out of the box.
Common Signs of a Failing Engine Control Module
- ✔ The Check Engine Light is illuminated, often with diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ Your vehicle experiences unexplained stalling or has trouble starting.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ The engine misfires, hesitates, or runs rough.
- ✔ Automatic transmission shifts erratically or harshly.
- ✔ Communication errors with other vehicle modules (U-codes).
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Acadia with an intermittent no-start condition that two other shops couldn’t solve. The vehicle would run fine for days, then refuse to start, showing no specific codes. After checking all the usual suspects—battery, starter, fuel pump—I focused on the network. Using a scope, I noticed a voltage drop on the 5-volt reference circuit originating from the ECM, but only during hot soak conditions. The internal processor was failing under heat. We installed one of these VIN-programmed ECMs, and the problem was solved for good. It’s a classic example of how a failing ECM can create ghost-like symptoms.
Why a VIN-Programmed 2010-2011 Enclave ECM is the Smart Choice
Ordering this module is more than just buying a part; it’s buying a complete solution. A new ECM from a dealership requires towing your vehicle to them for expensive programming. We handle that critical step for you. By providing your Vehicle Identification Number (VIN) at checkout, you ensure 100% correct software compatibility for your engine, transmission, and emissions system. This is the most reliable and cost-effective way to restore your vehicle’s factory performance.
Important Note for Camaro & LaCrosse Owners: For these specific models, the factory anti-theft (immobilizer) system is deeply integrated into the ECM. To provide a true plug-and-play solution, we will need you to send us your original module. We will professionally extract the immobilizer data and transfer it to your new ECM. We will contact you with simple instructions after your purchase.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the ECM: On the Enclave, Acadia, and Traverse, the ECM is typically located behind the engine’s fan shroud. For other models like the CTS or LaCrosse, check the LH or RH side of the engine compartment.
- ✔ Disconnect Connectors: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Do not force them.
- ✔ Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will reuse it.
- ✔ Install the New Module: Mount your new, pre-programmed ECM onto the bracket and securely fasten it.
- ✔ Reconnect Everything: Plug the electrical connectors firmly back into the new ECM until they click into place. Reconnect the negative battery terminal.
- ✔ Final Steps: Your vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. In most cases, the vehicle will start and run correctly immediately.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) allows us to load the exact, factory-correct software for your car’s specific configuration, including engine, transmission, and emissions options. This ensures the module works perfectly right out of the box.
Will I need to do any additional programming?
No, this ECM comes fully programmed. In some cases, a simple ‘security relearn’ procedure may be needed, which can be done without tools by cycling the ignition key. We include instructions for this easy process.
Where is the ECM located on my 2011 Enclave?
On the 2010-2011 Buick Enclave, the ECM is mounted to the rear of the engine cooling fan shroud, accessible from the top of the engine bay.
What if I have a Camaro or LaCrosse?
For these two models, we require your old ECM to transfer the immobilizer (anti-theft) data. This makes the new module plug-and-play and prevents a no-start condition. We will contact you with shipping instructions for your old unit after you place your order.
Is this a reliable, long-term fix?
Absolutely. We use high-quality components and the latest GM software updates to address common failure points, providing a dependable solution that restores your vehicle’s original performance and reliability.
