Is your Saturn VUE, Chevy Malibu, or GMC Sierra running rough, stalling, or displaying a persistent Check Engine Light? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. Don’t let a faulty computer keep you off the road or lead to more expensive repairs. This replacement ECM, part number 12629020 (interchangeable with 12597125 and others), is the reliable, cost-effective solution to restore your vehicle’s peak performance and efficiency.
We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). We flash it with the latest, most stable software updates directly from GM, ensuring optimal communication between your engine, transmission, and other onboard systems. This means no expensive trips to the dealership for programming—it arrives at your door ready for installation.
From the Diagnostic Bay
We had a 2009 Chevy HHR come into the shop with a bizarre, intermittent no-start condition. The owner had already replaced the battery, starter, and crankshaft position sensor. All the basic diagnostics checked out. On a hunch, we monitored the 5-volt reference signal from the ECM to the sensors. We found that on hot days, after the vehicle had been driven for a while, the voltage would drop erratically, causing the engine to stall and refuse to restart until it cooled down. The culprit was an internally failing ECM. Swapping in a VIN-programmed module like this one solved the problem instantly, saving the customer from further diagnostic headaches and parts-swapping.
Is Your Vehicle’s ECM Failing?
A failing Engine Control Module can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, it’s time to inspect your ECM.
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication, sensor circuits, or processor faults.
- ✔ Engine Performance Issues: Noticeable loss of power, poor acceleration, rough idling, or engine stumbling.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG is a strong indicator of an engine management problem.
- ✔ Intermittent Stalling: The engine cuts out unexpectedly while driving or when coming to a stop.
- ✔ No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
- ✔ Harsh or Erratic Shifting: The ECM plays a crucial role in transmission control, and a fault can cause jerky shifting or failure to shift into gear.
- ✔ Communication Errors: Your diagnostic scan tool is unable to communicate with the PCM.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide your vehicle’s VIN at checkout, and we will flash the unit with the correct GM software for your specific car or truck. It will be ready to install right out of the box.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific vehicle. It contains critical information about the make, model, year, engine, transmission, and factory-installed options. We use this information to load the precise software and calibrations your vehicle requires to run correctly.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, a check engine light can be triggered by many other failing components. It is always best to have the codes read with a diagnostic scanner to help confirm that the ECM is the source of the problem.
Is any special installation required after I plug it in?
In many GM vehicles, a security relearn procedure (also known as a VATS relearn) is necessary to sync the new ECM with your vehicle’s anti-theft system. This is a simple procedure that typically involves turning the key on and off in a specific sequence. Instructions are readily available online, and it does not require any special tools.
How can I confirm this part fits my vehicle?
This ECM fits a wide variety of GM models. The best way to confirm is to match the service number on your original computer to one of the numbers listed (e.g., 12597125, 12629020). If you are unsure, please provide us with your VIN, and we can verify compatibility for you.
