Get Your Dependable Truck Back on the Road
Is your Chevy Colorado or GMC Canyon acting up? If you’re dealing with a frustrating no-start condition, a rough idle, stalling, or a check engine light that just won’t go away, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the brain of your truck’s engine and transmission. When it fails, it can cause a cascade of confusing issues, leaving you without the reliable vehicle you depend on. This replacement module is the definitive, hassle-free solution to restore your truck’s performance and get you back to work and life with confidence.
Common Symptoms & Your Direct-Fit Solution
A faulty PCM can manifest in many ways, often mimicking other sensor failures. If you’ve replaced sensors and still have issues, it’s time to look at the central computer. This unit is engineered to solve those problems. We ship it pre-programmed specifically for your truck using your Vehicle Identification Number (VIN), making installation straightforward. The specific 2004-2006 Colorado PCM 12589311 is a common failure point, but this replacement provides a lasting fix for symptoms such as:
- Engine stalling or cutting out while driving
- Complete no-start or intermittent starting problems
- Poor fuel economy and sluggish acceleration

An Expert’s Note on VIN Programming
“In my 20 years of diagnostics, I’ve seen countless vehicle owners waste time and money chasing sensor codes when the PCM was the real culprit. For vehicles like the Colorado and Canyon with GM’s Passlock security system, VIN-specific programming isn’t just a convenience—it’s essential. An unprogrammed module simply won’t start the vehicle. We handle this critical step for you, ensuring the security handshake between the key, the body control module, and your new PCM works seamlessly right out of the box. It’s the difference between a quick driveway repair and an expensive tow to the dealer.”
Don’t let a faulty computer keep your truck sidelined. This is your opportunity to fix the problem correctly the first time. By providing a reliable, properly programmed 2004-2006 Colorado PCM 12589311, we help you restore the function and dependability you expect from your vehicle.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. It will arrive ready to be installed in your vehicle. In some cases, a simple ‘security relearn’ procedure may be required, which takes about 10-15 minutes and involves only your ignition key.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the vehicle itself. Look for a small metal plate on the driver’s side of the dashboard (visible through the windshield) or on the sticker inside the driver’s door jamb.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. The PCM is the central computer, and its failure can trigger a wide variety of codes. This replacement is designed to clear those root-cause electronic faults.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for a wide range of part numbers, including 12588650, 12591647, 12596783, 12604438, and many others listed in the description. As long as your vehicle is listed in the compatibility chart, we will program the correct software for a perfect match.
What if my truck has an anti-theft system?
Our VIN programming process accounts for your vehicle’s factory anti-theft system (like GM Passlock). After installation, you may need to perform a simple key-relearn procedure to sync the new PCM with your existing keys. Instructions are readily available and the process does not require any special tools.
