Restore Your Truck’s Reliability and Performance
Is your Chevrolet Colorado or GMC Canyon suffering from a persistent check engine light, erratic shifting, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) can be the hidden cause behind these headaches, leaving you stranded and stressed. It’s time to stop guessing and install a solution that brings back the dependable performance you rely on. This module, a direct replacement for part number 12569773, arrives at your door fully programmed to your vehicle’s specific VIN with the latest GM software updates. This isn’t just a part; it’s the first step toward a worry-free drive and renewed confidence in your truck.
Warning Signs and How to Overcome Them
A faulty PCM can manifest in numerous ways, often mimicking other sensor or component failures. By replacing it, you’re addressing the root cause and gaining significant benefits. Look out for these common symptoms:
- ✔ Persistent Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U-codes.
- ✔ Poor fuel economy that seems to have no other explanation.
- ✔ Harsh or unpredictable automatic transmission shifting.
- ✔ Engine stalling, stumbling, or rough idling.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
- ✔ Failure to pass state emissions testing.
Installing this professionally programmed 2004-2006 Colorado PCM provides the ultimate solution, restoring crisp engine response, smooth shifting, and factory-spec efficiency.
A Technician’s Note: The VIN is Your Vehicle’s DNA
“I’ve seen it countless times in the shop: a customer buys a module online, installs it, and the truck still won’t start or runs worse than before. Why? The programming wasn’t matched to the vehicle’s unique VIN. Your VIN tells the computer everything from the engine and transmission type to the axle ratio and tire size. We program this module specifically for your truck, ensuring every system communicates perfectly from the moment you turn the key. It’s the difference between a frustrating weekend and a successful, lasting repair.”
Guided Installation to Restore Peace of Mind
Replacing the PCM is a straightforward job you can tackle with basic hand tools. Our pre-programming service eliminates the need for expensive dealership tools, making this a confident DIY repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes for the system capacitors to discharge.
- Locate the Module: On the 2004-2006 Colorado and Canyon, the PCM is typically located on the right-hand (passenger side) of the firewall in the engine bay.
- Disconnect Wiring: Carefully release the locking tabs on the electrical connectors and gently pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old PCM: Unbolt the module from its mounting bracket. It’s usually held in place by a few small bolts or nuts.
- Install the New Module: Seat your new, pre-programmed 2004-2006 Colorado PCM onto the bracket and secure it. Reconnect the electrical harnesses, ensuring they click firmly into place.
- Final Steps: Reconnect the negative battery terminal. In some cases, a security relearn procedure (often called a CASE learn or Passlock relearn) may be necessary. This simple procedure can typically be done without special tools and instructions are widely available online for your specific model.

Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the critical process of loading your vehicle’s unique software and calibrations onto the module. Your Vehicle Identification Number (VIN) contains all the specific information about your truck’s engine, transmission, and options. We use it to ensure the PCM works perfectly with your exact configuration, just like the original from the factory.
Do I need to do anything after installing this PCM?
In most cases, the module is ready to go. However, some GM vehicles require a security relearn procedure (also known as Passlock or anti-theft relearn) to allow the engine to start. This is a simple procedure that involves cycling the key and can be done in your driveway without any special tools.
Is this a used part?
This is a high-quality, inspected, and verified OEM part that has been expertly prepared for your vehicle. Each unit undergoes rigorous testing to ensure it meets or exceeds original factory standards for performance and longevity before being programmed with the latest software for your VIN.
My original part number isn’t on your list, but my vehicle is. Will it work?
Often, GM releases updated part numbers that supersede older ones. The part numbers we’ve listed are the most common interchanges for this 2004-2006 Colorado PCM. If your vehicle is listed in our compatibility chart, this module is the correct replacement, even if your original number is slightly different.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information, so please provide it as soon as possible to avoid delays.
