Restore Peak Performance to Your GM Vehicle
Is your Saturn VUE, Chevy Malibu, or GMC Sierra running rough, stalling unexpectedly, or displaying a persistent Check Engine Light? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. This replacement PCM, service number 12597125 (hardware number 12635901), is the definitive solution to get your vehicle back on the road, running smoothly and efficiently. It’s not just a part; it’s a restoration of your vehicle’s core operational integrity.
The PCM is responsible for managing a complex web of systems, including fuel injection, ignition timing, transmission shifting, and emissions controls. When it begins to fail, the symptoms can be unpredictable and frustrating. Our unit arrives at your door fully programmed with the latest GM software updates, specifically tailored to your vehicle’s unique Vehicle Identification Number (VIN). This ensures a seamless installation and eliminates the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2009 Chevy HHR come into the shop with a bizarre issue. The customer complained of intermittent stalling, but only after it had been driven for 20 minutes and only on left turns. There were no consistent trouble codes, just a generic U-code for lost communication that would pop up occasionally. We checked wiring harnesses, grounds, and sensors for hours. Finally, on a hunch, we monitored the PCM’s internal temperature data. We noticed a sharp, illogical spike right before each stall. The thermal stress on the board was causing an internal connection to fail under specific conditions. We replaced it with a VIN-programmed unit like this one, and the HHR ran perfectly. It’s a reminder that PCM failures aren’t always straightforward, but a quality, correctly programmed replacement is always the right fix.
Is Your Vehicle Exhibiting These Symptoms?
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely that your engine computer is the culprit. Replacing your failing module with this pre-programmed unit can resolve these common issues.
- ✔ Persistent Check Engine Light (CEL) illuminated on your dash.
- ✔ Engine stalling or shutting off while driving.
- ✔ Rough idling or poor engine performance.
- ✔ A noticeable decrease in fuel economy.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication error codes with diagnostic scan tools.
The Importance of a VIN-Programmed 2008-2010 Saturn VUE PCM
Modern vehicles are incredibly complex, and the PCM is at the heart of that complexity. Simply installing a used computer from another vehicle will not work. The module is tied to the specific VIN for security (anti-theft systems), emissions compliance, and vehicle-specific options like engine size, transmission type, and tire size. Our process is simple: after you place your order, you provide us with your VIN. We then flash the module with the exact GM-certified calibration for your vehicle. This makes the installation process as close to ‘plug-and-play’ as possible, often only requiring a simple security relearn procedure that you can perform yourself.
This module is a direct replacement for a wide range of GM vehicles and is compatible with the following service numbers: 12612397, DL216140, 12594750, 12597125, 12629019, 12635902, and 12611549. Please verify your part number to ensure compatibility.
Frequently Asked Questions
Do I need to send you my old PCM?
No, there is no core charge or need to send us your old module. This is a direct purchase of a replacement PCM that is programmed and ready for installation in your vehicle.
What is the VIN and why do you need it?
The VIN (Vehicle Identification Number) is the unique 17-digit code for your car, usually found on the driver’s side dashboard or door jamb. We require your VIN to load the exact software and calibrations your specific vehicle needs to run correctly, including engine parameters, transmission settings, and anti-theft information.
Will this PCM be difficult to install?
Installation is typically straightforward. You will need to disconnect the battery, locate your old PCM, unplug the electrical connectors, and swap in the new one. In most cases, you will then need to perform a simple security relearn procedure, which can be done without special tools and instructions can be easily found online for your specific model.
Is this a brand new part?
This is a high-quality, inspected, and tested original equipment part that has been prepared for its next service life. Each unit is verified to be fully functional before being programmed with the latest GM software for your vehicle’s VIN.
What if my part number is not on the list?
The provided list covers the most common service numbers for this hardware. If your part number is different, please contact us with your vehicle’s year, make, model, and original part number. We can verify compatibility and ensure you receive the correct module.
