Expert Insight from Our Technicians
“We see it all the time. A customer buys a used computer from a salvage yard for their Trailblazer, plugs it in, and the truck won’t start. That’s because on these GM vehicles, the PCM is linked to the anti-theft system (PassLock). A module from another vehicle won’t recognize the key. Our process of programming the unit to your specific VIN before shipping eliminates this entire problem. It ensures the computer is ready to work with your exact vehicle, saving you from a massive headache and a tow bill to the dealership.”
Frequently Asked Questions
Is this PCM truly “plug and play”?
Yes. Because we program the module to your vehicle’s VIN before shipping, it is ready for installation right out of the box. In most cases, no additional procedures are needed. It’s designed to be a straightforward installation for a DIYer or professional mechanic.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians will use this number to flash the computer with the correct software for your specific make, model, and options. The unit will then be securely packaged and shipped to you.
Where do I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my specific check engine light codes?
This PCM is a guaranteed fix for internal module failure codes, such as P0601 through P0606. It can also resolve a wide variety of other codes caused by a faulty computer. However, if your codes are related to a failed external sensor (like an oxygen sensor or MAP sensor), you will still need to replace that sensor. This computer will restore the system’s ability to correctly read those sensors.
Does this computer fit other vehicles besides the Trailblazer?
Yes. This module, identified by part number 19209821 and its equivalents, fits a wide range of 2004-2006 GM trucks and SUVs, including the GMC Envoy, Isuzu Ascender, Hummer H3, and Chevy Colorado. We program it specifically for the vehicle VIN you provide, ensuring the computer communicates perfectly with your **2006 Trailblazer EXT PCM** or other compatible model.
