Restore Peak Performance to Your Vehicle
Is your 2011 Chevrolet Cruze or GM truck plagued by a persistent check engine light, erratic engine behavior, or a frustrating no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer responsible for managing your vehicle’s engine performance, fuel economy, and emissions. Don’t let a faulty computer keep you off the road. This direct-fit ECM, part number 12642100, is the reliable, pre-programmed solution you need to get your vehicle running smoothly again.
Unlike a generic module from a parts store or a costly trip to the dealership, this unit is specifically prepared for your vehicle. We take your Vehicle Identification Number (VIN) and flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility with your vehicle’s specific systems, including the engine, transmission, and emissions equipment. The result is a seamless installation and restored factory performance without the need for expensive diagnostic tools or programming services.
From the Diagnostic Bay
We recently had a 2011 Sierra 2500 with the 6.0L V8 towed in. The owner had spent a small fortune replacing the throttle body, MAF sensor, and all eight spark plugs chasing an intermittent stalling issue and a P0606 (Internal Control Module Processor Error) code. The truck would run fine for a day, then suddenly die at a stoplight. After confirming power and ground to the ECM were solid, we knew the internal processor was failing. Instead of a costly new unit from the dealer, we installed one of our pre-programmed modules. The customer provided his VIN, we flashed the unit, and after a simple 10-minute security relearn procedure, the truck fired right up and has been running perfectly ever since. It saved him hundreds of dollars and the headache of further misdiagnosis.
The Importance of a Programmed 2011 Cruze ECM
The 2011 Cruze ECM is more than just a box of circuits; it’s the brain of your vehicle. It constantly analyzes data from dozens of sensors to make real-time adjustments to fuel mixture, ignition timing, and transmission shifting. When it fails, the entire system is compromised. Symptoms can range from subtle annoyances to critical failures that leave you stranded. By choosing a module that is programmed specifically to your VIN, you are ensuring that all factory parameters and security information are correctly loaded, preventing communication errors and compatibility issues that can arise with un-programmed or incorrectly programmed units.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with communication-related codes (e.g., U-codes, P06xx codes).
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ Significant decrease in fuel economy.
- ✔ The vehicle cranks but refuses to start.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Inability to communicate with the ECM using a standard OBD-II scan tool.
- ✔ Cooling fans running constantly, even when the engine is cold.

Frequently Asked Questions
Do I need to program this ECM?
No. We program the module for you before it ships. We use your vehicle’s VIN to load the correct GM-certified software and updates, making it ready for installation.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This ensures we load the exact software for your car’s specific configuration.
Is this a plug-and-play installation?
For the most part, yes. After installing the module, you may need to perform a simple security relearn procedure, also known as a key relearn. This can typically be done without any special tools and involves a sequence of key turns. Instructions are widely available online for your specific model.
How do I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, this part will resolve the issue. It is crucial to have your vehicle properly diagnosed to ensure the ECM is the root cause of the problem before ordering.
What other part numbers does this ECM replace?
This module is a direct replacement for part numbers 12616532, 12642100, and 12656958. If your original module has one of these numbers, this part will fit and function correctly.
