This direct-fit, professionally programmed PCM, service number 12597125, is the definitive solution to restore your vehicle’s performance, efficiency, and reliability, getting you back to a smooth, worry-free drive.

This means it arrives at your doorstep ready for a straightforward installation, with no need for expensive dealership programming tools. It’s the most effective way to solve complex issues and regain the crisp, responsive performance you’ve been missing.
Warning Signs and How to Overcome Them
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your solution:
- ✔ Unexplained Check Engine Light (CEL) illumination
- ✔ Stored diagnostic trouble codes (DTCs) like P0601, P0606, or other internal processor faults
- ✔ Vehicle refuses to start or has intermittent starting issues
- ✔ Poor engine performance, hesitation, or stalling
- ✔ Decreased fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Communication errors with diagnostic scan tools
Guided Installation for a Confident Fix
Replacing your PCM is a manageable job for a confident DIYer. Follow these general steps to get your vehicle running smoothly again.
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery. This is a critical step to prevent electrical shorts.
- Locate the Old Module: Find the existing PCM. On many vehicles like the G6 or Cobalt, it’s located in the engine bay, often near the front left side or attached to the air cleaner box.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed PCM in the same location. Securely plug in the electrical connectors, ensuring they click into place.
- Reconnect and Start: Reconnect the negative battery terminal. The vehicle may require a security or crankshaft position relearn procedure, which can often be completed with a few simple key cycles or a short drive.
An Expert’s Diagnostic Tip
Before condemning your PCM, take a moment to check the fundamentals. A weak or failing battery and corroded engine ground straps can cause voltage drops that mimic the symptoms of a bad computer. I’ve seen countless vehicles come into the shop with PCM-related codes that were ultimately solved with a new battery or by cleaning the main ground connection to the chassis. Always verify you have a solid 12.6V and clean, tight connections first!

Frequently Asked Questions
What does “programmed to my VIN” mean?
It means we load the module with the specific software and calibrations for your vehicle’s exact configuration—engine, transmission, and options—using your Vehicle Identification Number (VIN). This ensures it works correctly right out of the box, just like a part from the dealership, but without the hassle.
Where do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is the most critical step.
Will I need to do anything after installation?
In many cases, the module is plug-and-play. However, some vehicles may require a simple security relearn or a crankshaft variation relearn procedure. These can typically be done without special tools and instructions can be readily found online for your specific model.
Is this a used part?
This is a professionally prepared, OEM-quality engine computer that has been thoroughly inspected, tested, and loaded with the latest software for your vehicle. It is guaranteed to restore function and is backed by our warranty for your peace of mind.
Will this fix my specific problem?
This module is a direct solution for an internally failed PCM. While it resolves the vast majority of issues listed, it’s always best to have your vehicle properly diagnosed to ensure the PCM is the root cause and not a separate sensor or wiring issue.
