Restore Peak Performance to Your GM 3.6L Engine
Is your Buick Enclave, GMC Acadia, or other GM vehicle running rough, stalling unexpectedly, or refusing to start? A failing Engine Control Module (ECM) is often the culprit. As the ‘brain’ of your engine, a faulty ECM can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement ECM, part number 19300014, is the reliable solution to get your vehicle back on the road, running smoothly and efficiently. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s VIN before it ships.
Case Study: A Tricky Diagnosis
I remember a 2011 Traverse that came into my shop with a complaint that stumped two other mechanics. The owner reported random stalling at traffic lights and a persistent Check Engine Light with a P0606 (ECM/PCM Processor Fault) code that would return immediately after being cleared. We checked all the wiring, grounds, and sensor inputs—everything looked perfect. The issue was intermittent, making it a nightmare to pinpoint. Finally, we swapped in a known-good, correctly programmed ECM. The stalling vanished, and the code never returned. It was a classic case of internal module failure that only a replacement could fix. This is why a dependable, properly programmed 2010-2011 Enclave ECM isn’t just a part; it’s peace of mind.
Is Your Vehicle Exhibiting These Common ECM Failure Symptoms?
A failing ECM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your engine’s computer needs attention:
- ✔ Check Engine Light is on with codes like P0601, P0606, or other communication errors (U-codes).
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained drops in fuel economy.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Transmission shifting issues or erratic behavior.
- ✔ Failure to pass state emissions testing.
- ✔ Apparent loss of spark or fuel injector pulse.
A Straightforward Guide to Installation
Replacing the ECM on these GM vehicles is a manageable job for a DIY enthusiast or any professional technician. Our pre-programming service eliminates the need for expensive dealer-only tools. For your 2010-2011 Enclave ECM replacement, follow these general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to ensure all systems are powered down.
- Locate the ECM: On most of these crossover models (Enclave, Acadia, Traverse), the ECM is located behind the cooling fan shroud. On sedans like the CTS or LaCrosse, it’s typically in the engine compartment on the passenger or driver’s side.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM in place and securely fasten the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new ECM until they click securely. Reconnect the negative battery terminal.
- Final Steps: Depending on the vehicle, a security relearn procedure may be necessary. This can typically be done without special tools by cycling the key. Instructions are widely available or can be provided upon request.
A Special Note for Camaro and LaCrosse Owners
Due to the specific anti-theft (immobilizer) systems in the 2010-2011 Chevrolet Camaro and Buick LaCrosse, we require your original ECM to be sent to us. This allows our technicians to read the unique immobilizer data and transfer it to your new module, ensuring a true plug-and-play installation without any further security procedures. We will contact you with shipping instructions after your purchase.

Frequently Asked Questions About Your 2010-2011 Enclave ECM
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you can send us your 17-digit Vehicle Identification Number (VIN) through the messaging system or include it in the notes at checkout. We cannot ship your module until we receive the VIN.
Is any additional programming needed after installation?
No! Our service includes programming the ECM with the latest GM software updates matched to your VIN. For most models, it’s a direct installation. Some vehicles may require a simple key-cycle security relearn, which doesn’t require any special tools. We provide instructions for Camaro and LaCrosse models.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty ECM, such as internal processor faults (P0606), communication errors, or failed injector drivers. While it solves many common problems, ensure your vehicle has been properly diagnosed by a professional, as other parts (like sensors or wiring) can cause similar symptoms.
What does ‘VIN-programmed’ actually mean?
VIN programming means we load the specific software and calibrations from GM that are intended for your exact vehicle. This includes settings for the engine, transmission, emissions equipment, and other options your vehicle was built with, ensuring seamless integration and optimal performance.
Is this compatible with other part numbers?
Yes, this ECM is a direct, interchangeable replacement for several part numbers, including 19300015, 12617230, 12636355, and 12635019. If your original module has one of these numbers, this part will work for you.
