Restore Peak Performance to Your GM Truck or SUV
Is your Cadillac Escalade, GMC Sierra, or Chevrolet Silverado experiencing perplexing issues like stalling, poor fuel economy, or an illuminated Check Engine Light? The Engine Control Module (ECM), often called the vehicle’s main computer, is the central command for all critical engine functions. When it begins to fail, it can cause a cascade of problems that affect drivability, reliability, and performance. This replacement ECM, part number 12633238, is the definitive solution to restore your vehicle’s factory operation.
This isn’t just a generic part off a shelf. We provide a vital service by programming this module specifically for your vehicle using your unique Vehicle Identification Number (VIN). This ensures that the ECM has the latest software updates directly from GM and is perfectly calibrated for your vehicle’s specific engine, transmission, and emissions equipment. This VIN-specific programming makes installation straightforward, eliminating the need for expensive dealership programming.
Expert Pro Tip
Before you condemn your ECM, take a moment to check the basics. A weak or failing battery, corroded battery terminals, or a loose ground strap can cause voltage fluctuations that mimic the symptoms of a bad computer. Always ensure your battery is fully charged and all main power and ground connections are clean, tight, and free of corrosion. This simple check can save you time and money in your diagnosis.

- ✔ Unexplained engine stalling, hesitation, or rough idling.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The engine cranks but refuses to start.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) contains critical information about your vehicle’s specific build, including the engine, transmission, emissions systems, and other options. We use the VIN to load the exact GM-certified software and calibrations for your vehicle, ensuring perfect compatibility and function right out of the box.
Is this ECM difficult to install?
For most DIY mechanics, the physical installation is straightforward. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, unbolting it, and then reversing the process with the new one. Some vehicles may require a security or anti-theft relearn procedure afterward, which can often be done at home. We recommend consulting a repair manual for your specific model’s procedure.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are caused by a faulty ECM, then this replacement part will resolve the issue. However, the check engine light can be triggered by many other components. It is essential to have a proper diagnosis performed to confirm the ECM is the root cause of the problem before ordering.
