Restore Peak Performance to Your TrailBlazer
Is your 2006 TrailBlazer EXT suffering from frustrating issues like a persistent check engine light, erratic shifting, a rough idle, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the computer that acts as the brain for your engine and transmission. Driving with a faulty PCM can lead to poor fuel economy, failed emissions tests, and unpredictable behavior on the road. Don’t let a bad computer keep your reliable SUV sidelined. This module is the straightforward, professional solution to get you back behind the wheel with confidence.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, this pre-programmed module is your definitive fix:

- Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U0100
- Harsh or delayed transmission shifting
- Unexplained drop in fuel mileage
- Engine stalling, stumbling, or hesitating
- Complete no-start or intermittent starting problems

Expert Insight: Why VIN Programming is Non-Negotiable
Many people think they can grab a used computer from a junkyard and simply swap it in. On modern vehicles like your TrailBlazer, this will not work. The PCM is tied directly to your vehicle’s anti-theft system (GM’s PassLock II or PassKey III). A module from another vehicle will prevent your engine from starting. Furthermore, your SUV has specific calibrations for its engine, transmission, and emissions equipment. Our VIN-specific programming ensures all these critical systems, including the anti-theft security, are perfectly matched, making the installation as simple as swapping the part.
By purchasing this 2006 TrailBlazer EXT PCM, you are choosing a reliable and intelligent repair. We handle the complex technical work so you can focus on the simple installation. Restore your vehicle’s drivability and eliminate those nagging electronic gremlins for good.
Frequently Asked Questions
Do I need to do any additional programming after installation?
No. This 2006 TrailBlazer EXT PCM comes fully programmed to the VIN you provide. In most cases, it is a direct plug-and-play installation. However, some vehicles may require a ‘CASE Relearn’ (Crankshaft Position System Variation Learning) procedure, which can be done with a capable scan tool. This syncs the new PCM with the crankshaft position sensor for optimal timing and misfire detection.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is this the correct part for my truck?
This unit fits the vehicles listed in the compatibility chart and replaces all part numbers shown. Please verify that your vehicle and original part number are listed. If you are unsure, feel free to contact us with your VIN, and we will be happy to confirm the fitment for you.
What if my original part number isn’t on the list?
The part numbers listed represent the most common compatible units. However, GM often has many superseded numbers. If your part number is not on the list, please contact us with your VIN. We can verify if this module is the correct service replacement for your specific vehicle.
What tools are needed for the installation?
Installation is typically straightforward and requires basic hand tools, such as a socket set to remove the module’s mounting bolts and connectors. It is crucial to disconnect the vehicle’s battery before beginning the installation to prevent any electrical damage.
