Is Your Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
If you’re experiencing frustrating and unpredictable engine problems, a failing Engine Control Module (ECM) is often the culprit. As the central computer of your vehicle, the ECM controls everything from fuel mixture and ignition timing to transmission shifting and emissions. When it starts to fail, it can cause a cascade of issues that are difficult to diagnose and can leave you stranded. Don’t let a faulty computer dictate your vehicle’s reliability. This direct-fit replacement ECM is the definitive solution to restore your vehicle’s performance, efficiency, and dependability.
This unit, service number 12590032, is a genuine OEM component that has been meticulously tested and is ready for installation. The most critical part of the replacement process is programming, and we handle that for you. Upon purchase, simply provide us with your vehicle’s VIN, and our technicians will flash the module with the latest GM-certified software specific to your car. This ensures perfect communication between the ECM and all other vehicle systems, eliminating the need for an expensive trip to the dealership.

This procedure can typically be done without special tools and instructions are readily available online for most models.
Frequently Asked Questions
What is an ECM and why is it so important?
The Engine Control Module (ECM), sometimes called the Powertrain Control Module (PCM), is your vehicle’s main computer. It processes data from dozens of sensors to manage engine performance, fuel efficiency, emissions, and transmission operation. A properly functioning ECM is absolutely critical for a smooth and reliable driving experience.
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to program the ECM with the exact software and calibrations for your specific vehicle. This includes engine type, transmission, emissions standards, and other options. This VIN-specific programming is essential for the module to work correctly and is a service that dealerships charge hundreds of dollars for.
Is this part difficult to install?
The physical replacement is usually simple, involving disconnecting the battery, unplugging a few electrical connectors, and removing a few bolts. However, after installation, you will likely need to perform a security relearn procedure to sync the new ECM with your vehicle’s anti-theft system. This procedure varies by model but is often straightforward.
How can I be sure my ECM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis is best. Common diagnostic trouble codes pointing to a bad ECM include P0600-P0606. If you’ve ruled out other components like sensors, wiring, and fuel delivery, the ECM is the most likely cause.
My original part has a different service number. Will this one work?
Yes, as long as your original number is on our interchange list (12590032, 12602044, 12603530, etc.), this module is a compatible replacement. Manufacturers often update part numbers over time, but the core hardware and function remain the same.
