Is Your GM Vehicle Running Rough, Stalling, or Shifting Erratically?
A failing Powertrain Control Module (PCM) can be the source of countless frustrating and hard-to-diagnose issues. If your Camaro, Impala, Grand Prix, or other GM vehicle is experiencing unpredictable behavior, a faulty engine computer is a likely culprit. This isn’t just an inconvenience; it’s a matter of reliability and safety. You need a solution that gets you back on the road with confidence, and this is it. This is a direct-fit replacement for part numbers 12209624 and 12210234, professionally programmed to your vehicle’s specific VIN.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless DIYers try to save a few dollars by grabbing a used computer from a salvage yard. It almost never works. On these GM vehicles, the PCM is tied directly to the car’s anti-theft system (VATS/Passlock) and specific options like engine size, transmission type, and even tire size. Without being correctly programmed to your exact VIN, the module won’t communicate with the rest of the car, resulting in a no-start condition. Our process eliminates that entire headache. We handle the complex programming so you receive a Programmed 12209624 PCM that is truly ready for installation.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This PCM comes fully programmed to the VIN you provide. The process is designed to be plug-and-play. Simply disconnect your battery, swap the modules, reconnect the battery, and you’re ready to go.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. We cannot ship the part until we have this information to complete the programming.
Will this fix my check engine light?
This module will resolve any diagnostic trouble codes (DTCs) that are directly caused by a failing computer. However, if your check engine light is on due to a separate mechanical or electrical issue (like a bad sensor), you will still need to address that problem. Proper diagnosis is always recommended.
Is this compatible with my specific vehicle?
This part fits a wide range of GM models as listed in the fitment guide. The most important step is to verify that your original module has the part number 12209624 or 12210234 printed on it. Matching the part number is critical for compatibility.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is most accurate for this part as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to a computer that only controls engine functions.
