Is Your Colorado Stalling, Shifting Erratically, or Refusing to Start?
A failing Powertrain Control Module (PCM) can bring your dependable truck to a grinding halt. If you’re dealing with a persistent check engine light, rough idling, poor fuel economy, or other frustrating electronic issues, you’ve found the solution. This isn’t just a replacement part; it’s a direct-fit, fully programmed module designed to restore the factory performance and reliability of your truck. We take the guesswork out of the repair by programming this computer specifically to your vehicle’s VIN before it ever leaves our facility.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing engine computer is the likely culprit:
- Check Engine Light: Especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0605, or P0606.
- No-Start Condition: The engine cranks but won’t fire up, often due to a lack of fuel injector or ignition coil command.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel mileage.
- Erratic Shifting: The transmission may shift harshly, get stuck in a gear, or shift at the wrong times.
- Intermittent Stalling: Your truck may stall for no apparent reason, either while driving or at idle.
This pre-programmed 2004-2006 Chevy Colorado PCM is the definitive fix for these issues. By replacing your old, failing unit with this professionally flashed module, you are restoring the very brain of your vehicle’s powertrain, ensuring all components work in perfect harmony as the manufacturer intended.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your truck. It contains critical information about your vehicle’s specific options, engine, transmission, and security system. We use the VIN to load the exact correct software onto the PCM, ensuring it works perfectly with your truck.
Is this a simple plug-and-play installation?
Yes, this is a direct-fit replacement. After installation, you may need to perform a simple security relearn procedure, which can typically be done without special tools and takes about 30 minutes. Instructions are readily available online or in service manuals. In some cases, a CASE (Crankshaft Angle Sensor Error) relearn may be needed with a scan tool for optimal performance.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (indicated by codes like P0601, P0606, etc.), then this part will resolve the issue. It’s important to properly diagnose your vehicle to ensure the PCM is the root cause of the problem.
What vehicles does this part fit?
This 2004-2006 Chevy Colorado PCM is also compatible with the GMC Canyon, Hummer H3, Isuzu Ascender, and several other GM models from the same era. Please refer to the detailed fitment list on this page to confirm compatibility with your specific vehicle.
How does the one-year warranty work?
This unit is backed by our one-year replacement warranty. In the unlikely event of a part failure within one year from the date of purchase, we will provide a replacement unit. Please contact our customer service for assistance with the process.
