Restore Peak Performance to Your Vehicle
Is your car suffering from a persistent check engine light, rough idling, stalling, or poor fuel economy? These frustrating issues often point to a failing Engine Control Module (ECM), the brain of your vehicle’s engine. This replacement ECM is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN. This eliminates the need for expensive dealership programming, getting you back on the road quickly and confidently.
Common Symptoms & Your Solution
A faulty engine computer can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, this pre-programmed module is your answer:
- Unexplained Check Engine Light (CEL) activation
- Diagnostic Trouble Codes (DTCs) related to the processor, such as P0601, P0602, P0603, P0604, P0605, or P0606
- Engine misfires, hesitation, or stumbling during acceleration
- Poor or erratic automatic transmission shifting
- A noticeable decrease in fuel efficiency
- The vehicle fails to start, or starts and then immediately stalls
By installing our professionally programmed 2012 Impala ECM 12637106, you are not just replacing a part; you are restoring your vehicle’s original performance, efficiency, and reliability.
Expert Insight: The Critical Role of VIN Programming
Many people consider buying a used ECM from a salvage yard, but this often leads to more problems. A module from another vehicle contains the wrong VIN, security information (anti-theft), and settings for different options. This mismatch will prevent your car from starting and functioning correctly. Our process ensures this module is a perfect digital match for your car. We flash it with the latest GM-certified software using your VIN, so it communicates seamlessly with your vehicle’s other systems right out of the box. It’s the smart, reliable way to do the job right the first time.

Frequently Asked Questions
Do I need to program this ECM?
No. We handle all the programming for you before shipment. This module will arrive ready for installation, programmed to the VIN you provide.
How do I provide my VIN?
After you complete your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Will this fix my car’s specific problem?
This ECM corrects issues directly caused by a faulty engine computer. While it resolves the most common symptoms like processor-related codes and erratic engine behavior, it’s essential to ensure your vehicle has been properly diagnosed by a qualified mechanic. This part will not fix problems caused by other faulty sensors or mechanical issues.
Is any additional setup required after installation?
In many cases, the installation is straightforward. However, some vehicles may require a security relearn procedure (often called a key relearn or anti-theft relearn) which can typically be done without special tools. Instructions for this simple procedure are widely available online for your specific model.
