Is Your Vehicle Running Rough? The PCM Might Be the Culprit.
If your Chevrolet Malibu, Cobalt, HHR, or other compatible GM vehicle is experiencing frustrating issues like a persistent Check Engine Light, erratic engine behavior, stalling, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the root cause. As the central computer for your engine and transmission, the PCM’s health is critical for your vehicle’s performance, reliability, and efficiency. Don’t let a faulty module keep you off the road. This direct-replacement PCM, service number 12597125, is the definitive solution to restore your vehicle’s factory performance.
From the Diagnostic Bay
We had a 2011 Chevy Malibu come in with a complaint that stumped two other shops: intermittent stalling at stoplights and a random P0606 (PCM Processor Fault) code that would appear and disappear. The owner had already replaced the throttle body and MAF sensor with no luck. After running a full diagnostic, we suspected the PCM itself was failing internally, especially when it got hot. We installed one of our VIN-programmed PCMs, performed the security relearn, and the car ran perfectly. The customer called a week later, thrilled that the stalling was gone for good. It’s a classic case of how a failing computer can mimic other mechanical problems, making proper diagnosis key.
Common Symptoms of a Failing GM PCM
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Unexplained engine stalling or stuttering
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Noticeable decrease in fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Communication error codes with diagnostic scan tools
- ✔ False sensor codes that return even after replacing the sensor
Why Our Programmed 2007-2012 Malibu PCM is the Right Choice
This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest challenge when replacing a modern vehicle’s computer is the complex programming required to make it communicate with your specific car. We eliminate that headache entirely. When you order, you provide us with your vehicle’s VIN. Our technicians then flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance, addressing any known bugs or drivability issues from the original factory software.
This module is a direct replacement for several service numbers, including: 12612397, 12594750, 12597125, 12629019, 12635902, and 12611549.

Frequently Asked Questions
Do I have to provide my VIN?
Yes, providing your Vehicle Identification Number (VIN) is mandatory. We use your VIN to load the correct, vehicle-specific software and calibrations from GM. This ensures the PCM works perfectly with your engine, transmission, and options package right out of the box.
Is this part difficult to install?
The physical installation is typically straightforward, requiring basic hand tools to disconnect the battery, unbolt the old module, and install the new one. However, after installation, you will need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn) to sync the new PCM with your vehicle’s keys. This procedure can usually be done without special tools and instructions are widely available online.
Will this fix my specific problem?
This PCM will resolve issues directly caused by a faulty module, such as internal processor errors (e.g., code P0606), driver circuit faults, and communication failures. While it can fix many performance problems, it’s important to properly diagnose your vehicle to ensure the PCM is the actual point of failure.
What vehicles does this PCM fit?
While it is a common part for the 2007-2012 Chevrolet Malibu, this PCM fits a wide variety of GM vehicles, including the Cobalt, HHR, G5, G6, Silverado 1500, Sierra 1500, Aura, Vue, and more. Please refer to the detailed fitment list on this page and match your original part’s service number to ensure compatibility.
Is any additional programming needed after I receive it?
No additional programming is required. We handle the critical flashing before shipment. The only step you may need to take is the security relearn procedure, which pairs the module to your car’s anti-theft system.
