Restore Peak Performance to Your Vehicle
Is your Saturn Vue, Chevy Malibu, or Pontiac G6 suffering from frustrating issues like a persistent check engine light, erratic shifting, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission. A faulty PCM can disrupt everything from fuel economy to engine timing, leaving you with an unreliable and inefficient vehicle. This replacement PCM, service number 12597125, is the definitive solution to get your car running smoothly again.
From the Diagnostic Bay
We had a 2009 Saturn Vue come into the shop with an intermittent stalling problem that was driving the owner crazy. It would run fine for days, then suddenly die at a stoplight. No codes were stored consistently. After checking fuel pressure, spark, and sensors, we hooked up a scope to the PCM outputs. We discovered the injector control signal would momentarily drop out, starved of its command from the module. We installed a VIN-programmed PCM just like this one, and the Vue has been running perfectly ever since. It’s often these hard-to-trace electronic gremlins that point directly to the vehicle’s brain.
Why Choose Our Programmed 2008-2010 Vue PCM?
Unlike a generic module from a parts store or a salvage yard, this unit is delivered to you ready for installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash the module with the latest, most stable software updates directly from GM. This critical step ensures that the computer is perfectly matched to your vehicle’s specific engine, transmission, and factory options. This eliminates the need for an expensive trip to the dealership for programming, saving you time and hundreds of dollars.
Common Symptoms of a Failing Engine Computer
- ✔ Persistent Check Engine Light (CEL) on your dashboard.
- ✔ Engine stalling, misfiring, or running rough.
- ✔ A noticeable decrease in fuel economy.
- ✔ The vehicle fails to start or is very difficult to start.
- ✔ Failed emissions testing due to incorrect engine parameters.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Loss of communication with diagnostic scan tools.

While this listing is focused on the 2008-2010 Vue PCM, it also fits dozens of other models such as the Chevy Cobalt, HHR, Impala, Silverado 1500, Pontiac G5, G6, and more. Please verify your original part number or contact us with your VIN to ensure perfect fitment. Installation is straightforward for a DIY mechanic or any professional technician. While the unit is plug-and-play, some vehicles may require a simple security relearn procedure to sync the new PCM with your keys, a process that typically takes 10-30 minutes and does not require special tools.
Frequently Asked Questions
Do I need to have this computer 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 during checkout, and the computer will arrive with the correct software, ready for installation.
What is a security relearn and is it difficult?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new computer to your vehicle’s existing keys. For most GM vehicles, it involves a sequence of turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’, and repeating this three times. We include instructions, and it requires no special tools.
Where is the PCM located on my 2009 Saturn Vue?
On the 2008-2010 Saturn Vue with the 2.4L engine, the Electronic Control Module (PCM/ECM) is typically located in the engine compartment. Location can vary on other compatible models, such as under the battery tray on a Silverado or on the firewall on a Saturn Aura.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. You can typically find your VIN on the driver’s side of the dashboard (visible through the windshield) or on the sticker in the driver’s side door jamb.
Is this part compatible with service number 12639669?
Yes. This PCM, part number 12597125, is a direct, updated replacement for several older service numbers, including 12639669. It will function identically and contains the most recent software corrections from the manufacturer.
