Programmed 2010 Allure Engine Control Module ECM 12616889

Is Your GM Vehicle Running Rough? The Problem Might Be Its Brain.

If your Buick, Cadillac, or Chevy is suddenly stalling, refusing to start, shifting erratically, or flashing a persistent Check Engine Light, the issue might not be a simple sensor. As a technician with over two decades of experience under the hood, I’ve seen these exact symptoms countless times. Often, the root cause is a failing Engine Control Module (ECM)—the central computer that manages everything from fuel injection to transmission timing. When it falters, the entire vehicle’s performance suffers, leaving you stranded and frustrated.

This isn’t just a replacement part; it’s a direct solution. We provide a fully tested Engine Control Module, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures that all factory settings and the latest GM software updates are loaded before it even ships. You get a component that is ready to restore your vehicle’s original performance and reliability.

Why Choose a VIN-Programmed ECM?

Getting the right module is only half the battle. Without correct programming, it’s just a metal box. A generic or non-programmed module will not communicate with your car’s other systems, leading to a no-start condition and a mandatory, expensive trip to the dealership for programming. We handle that for you.

• ✔ Eliminate Guesswork: Solves common ECM failure symptoms like random stalling, no-start, poor fuel economy, and false sensor codes.
• ✔ Save Time and Money: Arrives pre-programmed with the latest GM software. No dealer visit or specialized scan tools are required for programming.
• ✔ Plug-and-Play Design: Engineered to be a direct-fit replacement for the original module, making the installation process straightforward for a DIYer or professional mechanic.
• ✔ Wide Compatibility: This module is a direct replacement for several part numbers, ensuring a perfect match for a wide range of GM vehicles.

Simple Installation Guide for Your 2010 Allure Engine Control Module

Replacing the ECM is a manageable job that you can do in your own garage. Follow these steps for a smooth installation.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure the system is fully discharged.
2. Locate the ECM: On most compatible vehicles like the Buick Allure, Chevy Equinox, or Cadillac SRX, the ECM is found in the engine compartment, typically on the driver’s side (LH) near the fuse box or air filter housing. Refer to your owner’s manual for the exact location.
3. Disconnect the Old Module: Carefully release the locking tabs on the wiring harness connectors and pull them straight out. Avoid wiggling them side-to-side to prevent pin damage. Once disconnected, unbolt the module from its mounting bracket.
4. Install the New Module: Bolt the new, pre-programmed ECM into place. Firmly reconnect the wiring harnesses, ensuring they click and lock securely.
5. Reconnect the Battery: Reattach the negative battery terminal and tighten it.
6. Perform Relearn Procedure (If Necessary): In most cases, our VIN programming makes this step unnecessary. However, some vehicles may require a simple security or idle relearn procedure, which can typically be done by cycling the key and letting the vehicle idle for a few minutes. Your vehicle is now ready to drive!
