Is Your 2006 Impala Running Rough? The Engine Control Module Could Be the Culprit.
If your Chevrolet Impala is experiencing perplexing issues like random stalling, poor fuel economy, a persistent check engine light, or a complete failure to start, the problem may lie with its electronic brain: the Engine Control Module (ECM). The ECM is the central command center for your engine, managing everything from fuel injection and spark timing to emissions control and transmission shifting. When it begins to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it’s a critical component failure that can leave you stranded. Fortunately, there’s a straightforward, reliable solution.
The Direct Solution: A VIN-Programmed Engine Computer
This isn’t just a replacement part; it’s a complete, ready-to-install solution for your vehicle. We are offering a genuine GM Engine Control Module (service part number 12630457) that is professionally programmed to your specific vehicle using your VIN. This critical step ensures perfect compatibility and functionality right out of the box. Before we ship the module, our technicians will flash it with the latest, most stable software updates directly from GM. This process not only restores original performance but can also correct underlying factory bugs that may have existed in your old unit, leading to improved drivability and efficiency.
From the Diagnostic Bay
We had a 2006 Impala 3.5L come into the shop with a classic ‘ghost’ problem. The customer complained of intermittent stalling at stoplights and a check engine light that would come and go with various communication error codes. We checked the wiring, sensors, and grounds—everything seemed fine. After hours of chasing our tails, we suspected the ECM. Instead of installing a blank unit and towing the car to a dealer for expensive programming, we ordered a VIN-programmed module like this one. It arrived two days later, we plugged it in, performed the security relearn procedure, and the car fired up perfectly. All the ghost codes vanished, and the stalling issue was completely resolved. The customer saved hundreds on a tow bill and dealer programming fees.
Why Choose Our Programmed 2006 Impala Engine Module?
Getting your vehicle back to factory specifications shouldn’t be a complicated process. Our service is designed to eliminate the common headaches associated with ECM replacement. By providing us with your VIN at checkout, you ensure that the 2006 Impala Engine Module you receive is a perfect match, programmed to the exact calibration your vehicle requires. This eliminates guesswork and the need for specialized, expensive scan tools or a trip to the dealership for post-installation programming.

Frequently Asked Questions
Do I need to do any programming after I receive this module?
No. This ECM is delivered to you fully programmed to your vehicle’s VIN with the latest GM software. In most cases, you will only need to perform a simple security relearn procedure, which can be done without any special tools and takes about 30 minutes. We include instructions for this process.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module until we receive this information.
Is this a new or used part?
This is a high-quality, OEM-grade replacement part that has been thoroughly tested and prepared for your vehicle. It is guaranteed to meet or exceed original factory performance specifications.
What if my part number is slightly different but on the interchangeable list?
If your original module’s service number is on the provided list (e.g., 12590032, 12602044), this part is a 100% compatible replacement. GM often consolidates part numbers over time. We will program it to function perfectly for your vehicle based on the VIN you provide.
What is the security relearn procedure?
The security relearn, or anti-theft relearn, syncs the new ECM to your vehicle’s existing anti-theft system. The standard procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. We provide clear, step-by-step instructions with your order.
