An Expert’s Insight: From my 20 years on the shop floor, I’ve seen countless DIYers and even professional mechanics get stuck by installing a used, unprogrammed module. On these GM trucks, that’s a recipe for a no-start situation due to the Passlock anti-theft system. Our process of programming the module to your specific VIN before shipping isn’t just a convenience—it’s the critical step that ensures all systems communicate correctly the moment you turn the key. This is the key to a successful repair for your 2004-2006 Colorado PCM.
Frequently Asked Questions
Do I need to do any programming after I receive this PCM?
No. This module is completely plug-and-drive. We handle all the programming to your vehicle’s VIN before we ship it to you. Simply install it, and you’re ready to go.
Where do I provide my vehicle’s VIN?
You can add your 17-digit VIN to the notes section during checkout. If you forget, don’t worry—we will contact you via email to retrieve it before programming and shipping your part.
Will this fix my specific check engine light?
This module is the correct solution for internal PCM failure codes (like P0601) and many communication-related issues. While it fixes a wide range of problems, we always recommend a proper diagnosis to confirm the PCM is the root cause before ordering. A faulty sensor or wiring can sometimes mimic PCM symptoms.
What is a ‘CASE Relearn’ and will I need to do one?
A CASE (Crankshaft Angle Sensor Error) Relearn synchronizes the new PCM with your engine’s crankshaft position sensor. After installation, you may have a code P1336 stored. The vehicle will still run, but the light will remain until the relearn is performed. This procedure requires a capable bi-directional scan tool and is often performed by a professional mechanic.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for a wide range of part numbers, including 12569773, 12588650, 12593531, 12600818, and many more. As long as your vehicle is listed in the compatibility chart, this pre-programmed 2004-2006 Colorado PCM will work for you.
