Restore Your Camaro’s Performance and Eliminate Drivability Issues
Is your 2010-2011 Camaro suffering from a frustrating check engine light, erratic idling, stalling, or a sudden drop in fuel economy? These are classic signs of a failing Engine Control Module (ECM), the computer that serves as your vehicle’s brain. A faulty ECM can make your car unreliable and frustrating to drive. This replacement ECM is the definitive solution, arriving at your door pre-programmed with the latest GM software updates specifically for your vehicle’s VIN. This eliminates the need for expensive dealership programming, getting you back on the road with confidence.
As a technician with over two decades of experience, I’ve seen firsthand how a failing ECM can cause a cascade of confusing problems. It manages everything from fuel injection and ignition timing to transmission shifting. When it falters, the symptoms can be intermittent and difficult to diagnose. That’s why we offer this reliable, fully tested 2010-2011 Camaro ECM. It’s not just a part; it’s a complete solution designed to restore your vehicle’s factory performance and operational integrity.
From the Diagnostic Bay: The Ghost in the Machine
A customer brought in his 2011 Camaro 3.6L with a problem that was driving him crazy. It would randomly lose power for a split second on the highway, with no check engine light. We checked everything—fuel pressure, sensors, wiring harnesses—and couldn’t find a fault. Finally, during a long test drive with a data logger, we caught it: the ECM’s main processor momentarily dropped offline. It was a classic internal failure that wouldn’t always set a code. We installed one of these pre-programmed modules, and the car has run flawlessly ever since. It’s a reminder that sometimes the most elusive electrical gremlins live inside the main computer.
Signs Your Camaro’s Engine Brain is Failing
If you’re experiencing any of the following, a faulty ECM is a likely culprit. Replacing your failing module can resolve these common issues and prevent further damage to related components.
- âś” Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- âś” Unexplained stalling or engine hesitation, especially when warm.
- âś” Noticeable decrease in fuel efficiency.
- âś” Rough or inconsistent idling.
- âś” The engine cranks but refuses to start.
- âś” Communication errors with diagnostic scan tools (e.g., U0100 – Lost Communication With ECM/PCM).
- âś” Harsh or erratic automatic transmission shifting.
Your Straightforward Installation Guide
Installing your new 2010-2011 Camaro ECM is a manageable job for a DIY enthusiast. Follow these steps carefully for a successful replacement. Please note the special instructions for Camaro and LaCrosse models.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental reconnection.
- Locate the ECM: On the 2010-2011 Camaro, the ECM is typically located in the engine compartment. Consult your vehicle’s service manual for the exact position.
- Disconnect and Remove: Carefully unplug the wiring harness connectors from the old ECM. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the new ECM onto the bracket and securely tighten the bolts. Reconnect the wiring harness connectors, ensuring they click firmly into place.
- Reconnect Battery: Reattach the negative battery terminal.
- CRITICAL IMMOBILIZER STEP (Camaro & LaCrosse ONLY): For your new ECM to be truly plug-and-play, we must transfer the immobilizer (anti-theft) data from your old unit. After your purchase, we will provide instructions for you to send us your original ECM. We will perform this service and then ship your new, fully programmed module. This step ensures your car will start and run without needing a locksmith or dealer.
Verified Fitment for Your GM Vehicle
This ECM is a direct-fit replacement for a wide range of GM vehicles equipped with the 3.6L engine. It is compatible with part numbers 19300015, 19300014, 12617230, 12636355, and 12635019. Please verify your vehicle is on this list:
- Acadia: 2010-2011 (Electronic Control Module; behind fan shroud)
- Allure: 2010 (Electronic Control Module; LH engine compartment, 3.6L)
- Camaro: 2010-2011 (Electronic Control Module; 3.6L)
- CTS: 2010-2011 (Electronic Control Module; RH front engine compartment, 3.6L)
- Enclave: 2010-2011 (Electronic Control Module; behind fan shroud)
- LaCrosse: 2010-2011 (Electronic Control Module; LH engine compartment, 3.6L)
- Outlook: 2010 (Electronic Control Module; behind fan shroud)

- Traverse: 2010-2011 (Electronic Control Module; behind fan shroud)
How does the VIN programming work?
How does the VIN programming work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the exact, most current GM-certified software for your car’s specific configuration onto the ECM before we ship it.
Why do I need to send my old ECM for a Camaro?
For Camaros and LaCrosses, the ECM is tied to the vehicle’s anti-theft (immobilizer) system. To ensure your new module works without any extra steps, we need to read the security data from your original ECM and write it to the new one. We will contact you with simple instructions for this after your purchase.
Is this a plug-and-play part?
Yes, for most listed vehicles, it is completely plug-and-play. For the Camaro and LaCrosse, it becomes plug-and-play after we perform the immobilizer data transfer service from your original module. No further programming will be required.
Will this fix my check engine light?
If your check engine light is caused by an internal ECM failure (like codes P0601 or P0606), this part is the correct fix. However, you should always ensure other potential issues (sensors, wiring) have been properly diagnosed first. This module will solve any problems originating from the computer itself.
What if I have a different part number?
This module is a direct replacement for several part numbers, including 19300015, 12617230, 12636355, and 12635019. As long as your vehicle and engine match the fitment list, this ECM will work perfectly.
