There’s nothing more frustrating than a vehicle you can’t rely on. If your Chevrolet, GMC, or Cadillac is suffering from a persistent check engine light, erratic shifting, stalling, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed computer from a junkyard. It almost never ends well. Without proper VIN programming, the vehicle’s anti-theft system (like GM’s Passlock or VATS) will engage, preventing the engine from starting. Even if it does start, you’ll face incorrect transmission shifting, inaccurate gauge readings, and a host of other issues because the module is configured for a different vehicle’s options. Our VIN programming service isn’t an add-on; it’s the essential step that makes this part a true, reliable, plug-and-play solution for your truck or SUV.
Frequently Asked Questions
Do I need to program this module after I receive it?
No. We pre-program the module using the VIN you provide during checkout. It will arrive ready to be installed. In some cases, you may need to perform a simple anti-theft relearn procedure, which takes about 30 minutes and does not require any special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific problem or check engine light?
This 12602802 PCM is a direct solution for issues caused by a faulty module. While it resolves the most common electronic engine and transmission problems, we always recommend a proper diagnosis by a qualified mechanic to ensure the PCM is the root cause of your issue. A proper diagnosis will confirm that other components like sensors or wiring are not at fault.
Is this a brand new part?
This is a high-quality, fully tested, and functional component that has been meticulously inspected to meet or exceed original equipment standards. Each unit is verified for proper operation before being programmed and shipped.
Where is this module located on my vehicle?
On most compatible GM trucks and SUVs like the Silverado, Tahoe, and Escalade, the PCM is located in the engine bay, on the driver’s side, often under or next to the battery tray. On models like the Trailblazer or SSR, it may be located next to the air filter box.
