Frequently Asked Questions
Do I need to send my old computer (core) back?
No, there is no core charge or requirement to send your old module back to us. You can keep it or dispose of it as you see fit.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program or ship the module without it. This ensures the Programmed 2004-2006 Colorado PCM is a perfect match for your vehicle’s configuration.
Is this really a plug-and-play installation?
Yes, for the most part. The module is pre-programmed for your engine and transmission. After physical installation, you will need to perform a simple security relearn procedure, also known as the Passlock or anti-theft relearn. This procedure syncs the new PCM to your vehicle’s keys and can be done without any special tools, typically taking 30-40 minutes.
Will this fix my specific problem?
This PCM will correct any issues directly caused by a failing engine computer. While it solves the most common electronic problems, it’s essential to ensure your vehicle’s wiring and sensors are in good working order. This part is designed to fix internal module faults, such as those indicated by DTCs like P0601 (Internal Control Module Memory Check Sum Error).
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers any internal defects or programming faults with the module itself. It does not cover damage caused by improper installation or other vehicle electrical faults.
