Is Your GM Truck or Van Running Rough?
Dealing with a frustrating check engine light, erratic engine behavior, or a vehicle that just won’t start can bring your day to a grinding halt. These are classic signs that the brain of your vehicle, the Powertrain Control Module (PCM), has failed. When the PCM is on the fritz, it can cause a cascade of issues, from poor fuel economy and failed emissions tests to unpredictable stalling. You need a solution that’s not just a replacement part, but a complete, reliable fix. This is the definitive answer for your vehicle’s electronic woes.
Common Symptoms of a Failing PCM & Your Direct-Fit Solution
If you’re experiencing any of the following, a faulty module is the likely culprit. Common diagnostic trouble codes (DTCs) pointing to internal module failure include P0601, P0602, P0604, and P0606.

Expert Mechanic’s Insight: Many people don’t realize that a PCM isn’t just a generic computer. It’s tied directly to your vehicle’s security system, like GM’s Passlock or VATS. Simply swapping in a used module from another vehicle will result in a no-start condition every time. Our professional VIN programming service correctly syncs the module to your vehicle’s systems, making the installation process as seamless as possible and preventing security lockouts. This is the critical step that ensures your Programmed 12581565 PCM works correctly the first time.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of the engine and transmission, such as fuel injection, spark timing, and transmission shift points, to ensure optimal performance, fuel economy, and emissions.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your part until we have this information, as the programming is specific to your exact vehicle. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. Since our Programmed 12581565 PCM arrives ready to go, no computer setup is required.
Will I need to perform any other procedures after installation?
In some GM vehicles, a security relearn procedure may be necessary. This is a simple process that can usually be done without any special tools and involves a sequence of key turns. We can provide instructions for this if needed for your specific model.
Will this computer fix my vehicle’s problem for sure?
This PCM is a direct solution for an internally failed module. While it resolves the vast majority of issues described, it’s crucial to ensure your vehicle’s wiring, sensors, and other components are in good working order. Proper diagnosis is key to a successful repair.
