Is Your Truck Unreliable? Get Back to Work with a Dependable Solution.
There’s nothing more frustrating than a truck that won’t start, runs rough, or constantly throws a check engine light. For owners of a 2011 Sierra or Silverado, your vehicle is your lifelineโfor work, for towing, for getting things done. When the Engine Control Module (ECM) fails, your entire operation grinds to a halt. This isn’t just an inconvenience; it’s lost time and money. This VIN-programmed Engine Control Module is your direct-fit, reliable solution to get your truck back on the road and running like the day it left the factory.
Common Symptoms of a Failing ECM & Your Direct Solution
If you’re experiencing any of the following issues, a faulty engine computer is the likely culprit. This module is the definitive fix for problems stemming from the original unit. Our 2011 Sierra Silverado 6.0L ECM 12642100 is precisely programmed to eliminate these headaches:
- Persistent Check Engine Light (CEL) that won’t clear
- Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0606
- Engine stalling, stumbling, or running rough at idle
- Complete no-start or intermittent starting problems
- Poor fuel economy and a noticeable loss of power
- Communication errors with diagnostic scan tools
- Erratic automatic transmission shifting behavior

From the Shop Floor: We recently worked with a contractor whose 2011 Sierra 3500 was his mobile office. It started stalling randomly at job sites, costing him hours of productive time. His scanner showed a P0606 codeโinternal ECM failure. He was facing a week of downtime waiting for the dealer. We sent him our pre-programmed 2011 Sierra Silverado 6.0L ECM 12642100. He installed it in under an hour, performed the simple security relearn, and was back to work the next day. For him, it wasn’t just a part; it was a business-saving solution.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as we use it to program the computer specifically for your truck.
Is this ECM really plug-and-play?
Yes, for the most part. The module arrives with the correct engine and transmission software for your VIN. However, on most GM vehicles of this era, you will need to perform a simple security relearn procedure (often called the Passlock or anti-theft relearn) after installation. This takes about 30 minutes, requires no special tools, and syncs the new ECM to your existing keys. Instructions are readily available online or in service manuals.
How do I know this will fix my problem?
This module will resolve any issue directly caused by a faulty ECM. If you have diagnosed the problem to be the engine computer, or if you have specific internal processor fault codes (like P0601-P0606), this is the correct solution. It will not fix issues related to other failed sensors or wiring problems.
I see this also fits the Chevy Cruze. Is the process the same?
Yes. While the primary application is for the heavy-duty trucks, this module is also the correct computer for the 2011 Chevrolet Cruze with the 1.4L engine. The process is identical: provide your Cruze’s VIN, and we will program it with the correct software for your car before shipping.
What does ‘programmed with the newest updates’ mean?
General Motors often releases software updates to improve performance, fuel economy, and fix bugs discovered after the vehicle was built. When we program your module, we use the latest version of the software available from GM, ensuring your vehicle runs as efficiently and reliably as possibleโoften better than it did with the original, outdated software.
Where can I find my vehicle’s VIN?
Your VIN is a 17-digit number located 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.
