Restore Peak Performance to Your GM 3.6L Vehicle
Is your 2010-2011 Buick LaCrosse, Chevy Camaro, or Cadillac CTS running poorly? Are you battling a persistent Check Engine Light, experiencing intermittent stalling, or suffering from a no-start condition? The Electronic Control Module (ECM), the central computer of your vehicle’s engine, is often the culprit. This replacement ECM, part number 19300014, is the definitive solution to restore your vehicle’s original performance, drivability, and fuel efficiency.
The ECM is responsible for managing a complex web of sensors and actuators that control everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. Instead of continuing to chase symptoms, address the root cause with a reliable, correctly programmed replacement module.
From the Diagnostic Bay
We had a 2011 Cadillac CTS with the 3.6L V6 come into the shop on a tow truck. The owner had spent months and a small fortune at other shops trying to fix an intermittent stalling issue. They had replaced the fuel pump, spark plugs, and even a camshaft sensor, but the car would still die randomly at stoplights. After hooking up our professional scan tool, we noticed something odd: the ECM would intermittently lose communication with other modules right before a stall. A thorough check of the wiring and connectors revealed no issues. We determined the fault was internal to the ECM itself. We installed a VIN-programmed module, performed the necessary security relearn, and the car ran perfectly. The customer was thrilled to finally have a reliable vehicle again. It’s a classic case of how a failing computer can mimic mechanical problems, making a correct diagnosis essential.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Engine stalling or shutting off unexpectedly
- ✔ No-start or hard-start conditions
- ✔ Noticeable loss of engine power and acceleration
- ✔ Poor fuel economy
- ✔ Rough idling or misfires
- ✔ Automatic transmission shifting issues
- ✔ Communication errors with diagnostic scan tools
The Simple, Programmed Solution for Your 2010-2011 LaCrosse ECM
This isn’t just a part in a box. We provide a comprehensive service that makes this repair as straightforward as possible. When you order, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians will then use this VIN to flash the module with the latest, most up-to-date software directly from General Motors. This ensures the ECM is perfectly matched to your vehicle’s specific configuration, including its engine, transmission, and emissions equipment. This critical programming step eliminates compatibility issues and ensures a smooth installation process.
Important Note for Buick LaCrosse and Chevy Camaro Owners: Due to the specific anti-theft (immobilizer) systems used in these two models, a plug-and-play installation requires an extra step. We will need you to send us your original ECM. Our technicians will read the unique immobilizer data from your old module and write it to the new one. This makes the replacement truly plug-and-play, avoiding the need for expensive dealer tools or locksmith services for key relearning. We will contact you with shipping instructions after your purchase.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the ECM. Every vehicle has a unique configuration, and this step ensures the new module works perfectly with your engine, transmission, and options. It is essential for proper function and avoids compatibility problems.
Do I need to do any additional programming after installation?
For most compatible vehicles, this module is ready to install out of the box. However, some GM vehicles may require a simple security relearn procedure (often called a ‘key relearn’) which can typically be done without special tools. For LaCrosse and Camaro models, if you follow our process of sending in your old unit, no further programming will be needed.
Why do you need my old ECM for a LaCrosse or Camaro?
The LaCrosse and Camaro use a specific anti-theft system where the immobilizer data is stored in the ECM. To make the replacement plug-and-play and avoid a trip to the dealer, we must transfer this security information from your original module to the new one. This saves you time and money on locksmith or dealer fees.
Is this part compatible with my old part number 12636355?
Yes. This ECM is a direct replacement for several part numbers, including 19300015, 19300014, 12617230, 12636355, and 12635019. As long as your vehicle is on the fitment list, this module will work correctly.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming service is a mandatory and crucial part of the purchase, as an unprogrammed module will not function in your vehicle. Please provide your VIN during checkout or message it to us immediately after your purchase to avoid delays.
