Is Your Truck Running Rough? Get Back to Work with a Reliable Solution.
There’s nothing more frustrating than a truck that won’t run right. Whether you’re dealing with a persistent check engine light, poor fuel mileage, harsh shifting, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. Your GM truck or SUV is built to be a dependable workhorse, and this vital component is its brain. When it fails, it can bring everything to a halt. This module is the definitive solution to restore your vehicle’s performance and get you back on the road with confidence.

Expert Mechanic’s Insight
As a technician with over 20 years on the floor, I’ve seen countless DIYers get stuck after installing a used computer from a salvage yard. They don’t realize that modern GM vehicles have a sophisticated anti-theft system (VATS/Passlock) that is tied directly to the PCM and the VIN. A mismatched module will prevent the vehicle from starting, every time. Our process of programming the 2003-2007 Silverado 2500 PCM 12602802 specifically to your VIN before shipping completely bypasses this issue. It’s the critical step that ensures the module communicates correctly with the rest of your vehicle’s systems, making it a true plug-and-play repair.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot program and ship your module without it.
Will I need to do any extra programming after installation?
In most cases, no. The module is programmed to your VIN for engine and transmission operation. However, on some vehicles, a Case Relearn (Crankshaft Position System Variation Learning) may be needed with a capable scan tool to clear a specific check engine code. This does not prevent the vehicle from running.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, proper diagnosis is key. Common diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault) are direct signs of PCM failure. We also recommend checking all power and ground connections to the module before ordering.
Where is the PCM located on my vehicle?
On most compatible models like the Silverado, Sierra, and Tahoe, the PCM is located in the engine bay, on the driver’s side, underneath the battery tray.
Is this a genuine GM part?
This is a quality replacement Powertrain Control Module that is fully compatible with the listed GM service numbers and models. We load it with official GM calibration software to ensure it functions just like the original.
