Is Your Truck Running Rough? Get Back in Command.

If your GM truck or SUV is plagued by frustrating issues like a no-start condition, erratic engine performance, harsh shifting, or a dashboard full of warning lights, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical failure that sidelines your vehicle. This replacement Programmed 12602802 PCM is the definitive, reliable solution to restore your vehicle’s brain and get you back on the road with confidence.

Common Symptoms of a Failing PCM & Your Direct Solution

A faulty PCM can manifest in numerous ways, often mimicking other sensor failures and leading to frustrating, expensive, and incorrect repairs. If you’re experiencing any of the following, this module is your likely solution:

  • Engine stalling or misfiring unexpectedly.
  • Complete no-start condition where the engine cranks but won’t fire.
  • Transmission shifting erratically or getting stuck in one gear (limp mode).
  • Check Engine Light with communication error codes or false sensor codes (e.g., P0601, P0606).
  • Noticeable decrease in fuel economy and overall performance.

Instead of paying for expensive diagnostic time and dealership programming fees, this module arrives at your door already programmed to your vehicle’s specific VIN. It’s a straightforward fix designed for the real-world owner.

Expert Insight: The Critical Role of VIN Programming

As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used PCM from a salvage yard. In 99% of these cases, the vehicle still won’t start. Why? GM’s Vehicle Anti-Theft System (VATS) or Passlock is tied directly to the original PCM and VIN. A mismatched module will trigger the security system and immobilize the engine. Our service eliminates this entire problem. By programming your exact VIN before we ship, we ensure the new PCM is accepted by your vehicle’s other modules, making the installation process as seamless as possible.

Frequently Asked Questions

Do I need to do any programming myself?

No. We handle all the programming before shipping. The unit arrives flashed with your vehicle’s VIN and the latest GM updates, making it ready for installation. The only potential step is a simple security relearn, which you can do yourself.

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 program or ship the module without it. Please double-check it for accuracy to ensure a perfect match.

What if my original part number is slightly different?

This module, service number 12602802, is a compatible replacement for several other GM service numbers, including 89017750, 12582605, and 12589463. As long as your vehicle is on the compatibility list, this unit will function correctly.

Is a security relearn procedure required after installation?

Yes, on most GM vehicles from this era, a security relearn is necessary to sync the new PCM with your vehicle’s anti-theft system. It’s a simple 30-minute process that involves turning the key to the ‘ON’ position for 10 minutes, three times in a row. Instructions are widely available online, and no special tools are needed.

Will this Programmed 12602802 PCM fix my check engine light?

If the check engine light and associated codes are being caused by a faulty PCM, then yes, this part will resolve the issue. However, it’s essential to ensure your vehicle’s issues have been properly diagnosed, as this part will not fix problems related to failed sensors or other mechanical components.
