Restore Your Truck’s Performance and Reliability
Is your Chevrolet Colorado, GMC Canyon, or Hummer H3 suffering from frustrating and unpredictable engine problems? If you’re dealing with a persistent check engine light, rough idling, stalling, or poor fuel economy, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s reliability. We offer the definitive solution: a professionally programmed engine computer that gets you back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways, leaving you stranded or chasing endless repairs. If you’re experiencing any of the following, this module is the fix you need:
- Erratic or harsh transmission shifting
- Significant drop in fuel mileage
- Engine misfires or stumbling under acceleration
- Complete no-start condition where the engine cranks but won’t fire
- Diagnostic Trouble Codes (DTCs) such as P0601, P0602, P0606, or other communication errors.
Instead of buying a used module that requires expensive programming at a dealership, our 2004-2006 Colorado PCM arrives at your door fully programmed to your vehicle’s specific VIN. This ensures all systems communicate correctly and your truck runs exactly as the factory intended.

Expert Insight: Why VIN-Specific Programming is Non-Negotiable
Many people assume an engine computer is a one-size-fits-all part. On modern vehicles, that couldn’t be further from the truth. The PCM is the ‘brain’ that controls everything from the fuel injectors to the transmission shift points. Your vehicle’s VIN is linked to specific factory calibrations for your engine type, transmission, emissions equipment, and even tire size. Installing a generic or non-programmed module can lead to immediate drivability issues, system conflicts, and warning lights. Our process of programming this 2004-2006 Colorado PCM to your exact VIN ensures every one of those critical parameters is perfectly matched, giving you a seamless and effective repair the first time.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module is delivered to you fully programmed and ready for installation. In most cases, the only additional step required is a Crankshaft Position System Variation Learning procedure, also known as a CASE Relearn. This is a simple procedure that can be completed by any mechanic with a capable bi-directional scan tool.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your VIN. Simply reply to that email, and our technicians will handle the programming before shipping your part. Please ensure the VIN is 100% accurate to avoid delays.
Will this fix my specific check engine light codes?
This PCM is a common solution for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error) and P0606 (ECM/PCM Processor Fault). While it can resolve many other issues, we always recommend having a qualified technician perform a full vehicle diagnosis to confirm the PCM is the root cause of the problem before ordering.
Is this compatible with my 2006 Trailblazer or Envoy?
Yes. This module is compatible with a wide range of GM trucks and SUVs from this era, including the 2006 Trailblazer, Envoy, Rainier, and Hummer H3. Please check the detailed fitment list at the top of the page to confirm compatibility with your specific model and engine.
What if I install it and my truck still doesn’t start?
While this 2004-2006 Colorado PCM is the solution for many no-start conditions, other issues like a bad fuel pump, faulty crank sensor, or wiring problems can cause similar symptoms. We strongly advise a proper diagnosis to rule out other potential points of failure.
