Expert Insight: The VIN Programming Difference
Many owners are tempted to grab a used computer from a salvage yard, only to find it causes more problems than it solves. A PCM from another vehicle, even an identical Trailblazer, is coded to that specific vehicle’s options, security system (VATS), and emissions. Our process eliminates that risk entirely. By programming this 2006 Trailblazer PCM to your VIN, we ensure it communicates flawlessly with all other modules in your truck, just like the original one did from the factory. It’s the key to a successful and lasting repair.
Frequently Asked Questions
Is this module difficult to install?
No, installation is straightforward for someone with basic mechanical skills. The PCM is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old unit, unbolting it, and then installing the new one in the reverse order. Since our unit comes pre-programmed, no further steps are needed.
How do I provide my VIN number?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we have this information to program it correctly.
Will this fix my specific check engine light codes?
This 2006 Trailblazer PCM is the direct remedy for internal module failure codes like P0601 (Internal Control Module Memory Check Sum Error) and other communication-related faults. While it can resolve issues caused by faulty computer logic, please ensure your vehicle’s sensors and wiring have been checked for other potential problems.
What if my original part number isn’t on the list?
The part numbers listed are the most common, but GM often has many superseded numbers. As long as your vehicle is a 2006 Trailblazer with the 4.2L engine (or another compatible model listed), we can program this module for you. The VIN programming process ensures compatibility.
What does the one-year replacement warranty cover?
This unit is backed by our one-year replacement warranty. This covers any issues related to the proper function of the module itself. If the unit fails within one year of the purchase date, we will provide a replacement part.
