Get Your Truck Running Right Again
Is your 2004-2006 Chevy Colorado, GMC Canyon, or Hummer H3 suffering from frustrating issues like a persistent check engine light, poor performance, random stalling, or harsh shifting? These are classic signs of a failing Powertrain Control Module (PCM), the computer that serves as the brain of your vehicle’s engine and transmission. Don’t let a faulty computer keep you off the road. This is the direct, reliable solution to restore your truck’s performance and dependability.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of problems that are often misdiagnosed. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Erratic engine behavior (stalling, surging, rough idle)
- Transmission shifting problems or getting stuck in gear
- Drastic decrease in fuel economy
- Check Engine Light with codes like P0601, P0606, or U0100
- Vehicle won’t start, despite a good battery and starter
This module is the definitive fix. We take a genuine GM PCM and program it specifically to your truck’s Vehicle Identification Number (VIN). This ensures perfect communication with all other onboard systems, just like the original unit from the factory.

An Expert’s Note on GM Programming
“On these specific GM trucks and SUVs, the PCM is the heart of the vehicle’s security system, often called Passlock or Passkey. Simply installing a used, non-programmed computer from a junkyard will result in a no-start condition every time. The module MUST be matched to your vehicle’s unique VIN to be recognized by the other systems. Our VIN-programming service handles this critical step for you, making the repair process as seamless as possible and saving you from a major headache.”
Stop chasing down electrical gremlins and get the right part the first time. This programmed 2004-2006 Colorado PCM is the most effective way to solve complex engine management issues and get your reliable truck back in service. Providing your VIN is the key to a successful repair, and we make the process simple so you can get the job done right.

What if my truck has an anti-theft system?
Our programming matches the module to your vehicle’s security configuration. In some cases, a simple, 10-minute security relearn procedure may be required after installation. This procedure can be done without any special tools, and we can provide instructions if needed.
Is this guaranteed to fix my truck’s problem?
