2010 Allure Engine Control Module 12637106 | Programmed to Your VIN

Restore Your Vehicle’s Brain and Get Back on the Road

As a technician with over two decades of diagnostic experience, I’ve seen firsthand how a failing Engine Control Module (ECM) can turn a reliable vehicle into a source of constant frustration. It’s the central computer of your car, and when it starts to malfunction, you can experience everything from a simple check engine light to a car that refuses to start. If your Buick, Chevy, Cadillac, or Saab is suffering from erratic behavior, poor fuel economy, or mysterious electrical gremlins, the problem often traces back to this critical component.

This isn’t just a replacement part; it’s a complete solution. We are offering a genuine GM Engine Control Module, part number 12637106, that arrives at your doorstep programmed and ready for installation. We take your vehicle’s unique VIN and flash the module with the latest, most stable software updates directly from GM. This crucial step eliminates the need for an expensive trip to the dealership and the use of specialized scan tools, saving you both time and money. This is the professional-grade fix that you can perform right in your own garage.

Is Your GM Vehicle Showing These ECM Failure Signs?

A failing ECM can manifest in numerous ways. Over the years in my shop, I’ve learned to spot the classic symptoms. If you’re experiencing any of the following, a faulty module is a likely culprit:

• ✔ Check Engine Light is on with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
• ✔ Engine cranks but refuses to start.
• ✔ Intermittent stalling, especially when coming to a stop or at idle.
• ✔ Noticeable decrease in fuel efficiency.
• ✔ Rough or unstable engine idle.
• ✔ Harsh or incorrect automatic transmission shifting.
• ✔ Communication errors with other vehicle modules (U-codes).
• ✔ Loss of spark or fuel injector pulse for one or more cylinders.

A Straightforward Guide to Your ECM Installation

Replacing the ECM on these GM vehicles is a job most DIY mechanics can handle with basic tools. Our pre-programming service makes it a true plug-and-play repair. Just follow these general steps:

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge completely.
2. Locate the ECM: On most of these models (like the Allure, LaCrosse, Equinox, and Terrain), the ECM is located in the engine compartment on the driver’s side, often near the air filter box or firewall. Refer to your vehicle’s service manual for the exact location.
3. Disconnect Connectors: Carefully release the locking tabs on the electrical harness connectors and pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
4. Remove the Old Module: Unbolt the old ECM from its mounting bracket. There are typically a few 10mm bolts holding it in place.
5. Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it. Reconnect the electrical harnesses, ensuring they click securely into place.
6. Reconnect Battery: Reattach the negative battery terminal.
7. Perform Security Relearn (If Necessary): In some cases, a simple 10-minute key-on security relearn procedure may be required for the vehicle to recognize the new module. This typically involves turning the key to the ‘ON’ position for 10 minutes, then off, then starting the vehicle. We include instructions for this simple process.
