Restore Your Vehicle’s Performance and Reliability
Is your vehicle suffering from a persistent Check Engine Light, unpredictable stalling, or a frustrating no-start condition? These are common signs of a failing Engine Control Module (ECM), the critical computer that manages your engine’s performance. Don’t let a faulty computer keep you off the road. This direct-replacement ECM is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN, ensuring a seamless and effective repair.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of issues that are often misdiagnosed. If you’re experiencing any of the following, this module is the solution you need:
- Check Engine Light (CEL): Particularly for communication errors or internal processor fault codes (e.g., P0601, P0602, P0605, P0606).
- Engine Stalling or Misfiring: The engine may shut off unexpectedly while driving or run rough at idle.
- No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark commands from the ECM.
- Poor Fuel Economy: Incorrect signals can lead to inefficient engine operation and increased fuel consumption.
- Erratic Transmission Shifting: The ECM works with the transmission controller, and a failure can cause shifting problems.
By installing our professionally prepared programmed 12590032 ECM, you’re not just replacing a part; you’re restoring the central nervous system of your vehicle’s powertrain for reliable, consistent operation.

An Expert’s Note on VIN Programming
Many people wonder why VIN programming is so essential. In modern GM vehicles, the ECM is integrated with the anti-theft or immobilizer system (like Passlock or VATS). A non-programmed module from a junkyard simply won’t workโthe vehicle won’t recognize it and will not start. Our pre-programming service syncs the module to your car’s identity. This saves you from needing specialized, dealer-level scan tools and the significant cost associated with a dealership service appointment. We handle the complex part so you can focus on the straightforward installation.
Getting your car, truck, or SUV back to factory-spec performance is simple. Provide your VIN at checkout, and we’ll ship a fully configured programmed 12590032 ECM that’s ready to be installed right out of the box. It’s the most efficient way to solve complex electronic issues and drive with confidence again.
Frequently Asked Questions
Is any additional programming required after installation?
No. This ECM comes fully programmed to your vehicle’s VIN and is equipped with the latest software updates from GM. In most cases, it is a plug-and-play installation. Some vehicles may require a simple security relearn procedure, which can be done without any special tools and instructions are readily available online.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How can I be sure this is the correct part for my vehicle?
Please check the extensive fitment list on this page. The most reliable method is to match the service number from your original ECM to 12590032 or one of the interchangeable numbers listed. Providing us with your VIN during the programming process allows us to perform a final verification of compatibility.
What do the other service numbers mean?
Automakers often update parts over a vehicle’s production run. The other numbers (12602044, 12603530, etc.) are later service numbers that are electronically and physically identical to the original. Our programmed 12590032 ECM is a fully compatible replacement for all listed service numbers.
Where is the ECM located on my vehicle?
The location varies by model. Common locations for the vehicles this part fits include inside the engine bay (often on the firewall or inner fender), mounted to the air cleaner housing, or on the frame rail. A quick search for your specific year, make, and model will provide the exact location.
