Is Your Saturn, Cobalt, or Malibu Experiencing Engine Problems?
If you’re dealing with frustrating issues like a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it begins to fail, it can cause a wide range of confusing and debilitating symptoms, leaving your car unreliable and unsafe to drive. Don’t let a faulty computer keep you off the road. This direct replacement ECM is the reliable, cost-effective solution you need.
From the Diagnostic Bay
We had a 2007 Cobalt SS come into the shop with a classic complaint: intermittent stalling at stoplights and a P0601 Internal Control Module Memory Check Sum Error code that wouldn’t stay cleared. The owner had already replaced the spark plugs, ignition coils, and even the fuel pump on the advice of another shop, with no success. After confirming power and grounds to the ECM were solid, we knew the internal processor was failing. We sourced a quality used unit, programmed it to the car’s VIN, performed the security relearn, and the car ran perfectly. It’s a textbook example of how a faulty ECM can mimic other component failures, making accurate diagnosis key.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is on with codes related to the module itself (e.g., P0601, P0606).
- ✔ Unexplained drops in fuel economy.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Difficulty starting the engine or a no-start condition.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Misfire codes that persist even after replacing plugs and coils.
- ✔ Loss of communication with the diagnostic scan tool.

Frequently Asked Questions
Do I need to get this programmed by a dealer?
No. The main benefit of our service is that we program the ECM to your vehicle’s VIN before we ship it. This saves you the time, hassle, and expense of a trip to the dealership for programming.
What is a ‘security relearn’ and is it difficult?
A security relearn, or key relearn, is a simple procedure that syncs the new ECM with your vehicle’s anti-theft system. For most GM vehicles of this era, it involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. It requires no special tools and is something most owners can do themselves.
Is this a new part?
No, this is a high-quality, tested used ECM that has been sourced from a salvaged vehicle. Each unit is inspected to ensure it is in good working condition before being programmed and shipped.
My original part number is 12579132. Will this work?
Yes. Part numbers 12597520, 12579132, and 12615197 are interchangeable for the applications listed. We will ship a compatible hardware number programmed with the correct software for your vehicle.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
