Is Your Vehicle Running Rough or Not Starting at All?
The Engine Control Module (ECM), often called the engine’s brain, is the central command center for your vehicle’s performance, fuel economy, and emissions. When it begins to fail, it can cause a cascade of confusing and frustrating problems, from a simple check engine light to a car that won’t start. If you’re experiencing erratic engine behavior, poor fuel mileage, or stalling, a faulty ECM could be the culprit. This replacement Engine Control Module, service number 12590032, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2008 Chevy Impala come into the shop with a persistent P0606 (ECM/PCM Processor Fault) code. The owner had already replaced the spark plugs, ignition coils, and even the MAF sensor, but the car still hesitated and stalled intermittently. After hours of chasing electrical gremlins, we traced the issue to an internal failure in the original ECM. Instead of a costly trip to the dealer for a new unit and programming, we installed one of our VIN-programmed modules. The car started immediately, the check engine light was gone, and the engine ran smoother than it had in years. The customer saved hundreds of dollars and countless hours of frustration by getting a part that was ready to go right out of the box.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is illuminated, often with communication-related trouble codes (U-codes) or processor fault codes (P06xx).
- ✔ Engine stalling or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Poor engine performance, including hesitation or surging during acceleration.
- ✔ Automatic transmission shifting issues or harsh shifts.
- ✔ Problems with other electronic systems, as the ECM communicates with multiple modules.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This means it is ready for installation right out of the box, saving you a costly trip to the dealership.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We use this to load the correct GM-certified software and calibration files onto the module for your exact vehicle.
Is any additional setup required after installation?
In most cases, the module is plug-and-play. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available for your specific model.
How do I find my original part number?
Your original part or service number is printed on a sticker on the casing of your current ECM. You will need to locate the module in your vehicle (common locations include the engine bay, under the air cleaner housing, or on the firewall) and read the number directly from the label.
Will this fix my vehicle’s specific problem?
This ECM will correct issues directly caused by a faulty engine computer. While the symptoms listed are common for ECM failure, it is crucial to have your vehicle properly diagnosed by a qualified mechanic to ensure the ECM is the root cause of the problem before ordering.
