Frequently Asked Questions
What information do you need from me?
After you place your order, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to program the module with the exact software and calibrations for your truck’s specific engine, transmission, and options.
Is this module difficult to install?
No, for most models this is a straightforward process. The PCM is typically located in the engine bay on the firewall. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old unit, and installing the new one. Most DIYers with basic tools can complete the job in under an hour.
Will I need to do anything after installation?
In some cases, a security relearn procedure (also known as a CASE relearn) may be required. This is a simple process that can often be done without special tools and involves a sequence of key turns. We can provide instructions if needed. This ensures the module communicates correctly with your vehicle’s anti-theft system.
How do I know this will fix my problem?
While this programmed 2004-2006 Colorado PCM is the solution for a very wide range of electronic and drivability issues, we always recommend having a proper diagnosis performed by a qualified mechanic. This ensures you are replacing the correct part and not overlooking other potential issues like faulty wiring or sensors.
What if my original part number isn’t 12591648?
This module is a direct replacement for a long list of interchangeable GM part numbers. As long as your vehicle’s year, make, and model are listed in the compatibility chart, this unit will work perfectly once programmed to your VIN, regardless of the number on your original module.
