Restore Peak Performance to Your Pontiac Solstice
Is your 2008, 2009, or 2010 Pontiac Solstice suffering from frustrating issues like a persistent check engine light, poor fuel economy, rough idling, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. The PCM is responsible for managing critical engine and transmission functions, from fuel injection and ignition timing to emissions controls and automatic transmission shift points. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose and can sideline your vehicle indefinitely.
This replacement Engine Control Module, compatible with service number 12597125 and part number 12635901, is the definitive solution to get your Solstice running like new again. We take the guesswork and hassle out of the repair process. Unlike a generic part from a local store, this unit is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). This critical step ensures that the module has the correct software and calibrations for your Solstice’s specific engine, transmission, and options, straight from GM’s latest updates. This means no expensive trips to the dealership for programming—it’s ready for installation right out of the box.
From the Diagnostic Bay
We had a 2009 Solstice come into the shop that was driving the owner crazy. It would start and run fine for about 15 minutes, then suddenly the throttle would become unresponsive, and it would throw a half-dozen seemingly unrelated codes for sensors that all tested good. The owner had already replaced the throttle body and accelerator pedal position sensor with no luck. After hours of chasing wiring diagrams, we finally isolated the issue to the PCM. The internal processor was failing under heat soak, causing it to send corrupt data across the CAN bus network. Installing a VIN-programmed PCM like this one solved every single issue instantly. It’s a reminder that the PCM can create phantom problems that look like something else entirely.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or misfiring unexpectedly.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions tests.
- ✔ Intermittent or complete no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Do I need to have this PCM programmed by a dealer?
No. This PCM comes fully programmed to your vehicle’s specific VIN before it is shipped. It is ready for installation upon arrival, saving you a trip to the dealership and additional programming fees.
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This is typically found on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Is any additional setup required after installation?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure (also known as a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available online for your specific model.
How do I know if this part will fit my vehicle?
This part is a direct fit for the 2008-2010 Pontiac Solstice with the 2.4L engine. It also fits a wide variety of other GM vehicles. The best way to confirm compatibility is to match the service number from your original computer to one of the numbers listed in the description, such as 12597125 or 12635901.
What if my original part number isn’t on the list?
If your part number is not listed, please contact us with your vehicle’s VIN and the part number from your original module. We can verify compatibility or help you find the correct part for your application.
