Is Your GMC Envoy Running Rough, Stalling, or Showing a Check Engine Light?
Dealing with erratic engine behavior in your 2006 GMC Envoy can be incredibly frustrating. You rely on your SUV to be dependable, but a faulty Powertrain Control Module (PCM) can turn it into a source of constant worry. Whether you’re experiencing hard starts, poor fuel mileage, or confusing error codes, you’ve come to the right place for a reliable, straightforward solution. This module is the brain of your vehicle, and we provide a professionally programmed replacement that gets you back on the road with confidence.
Common Symptoms & Your Solution
A failing engine computer can manifest in numerous ways. If you’re seeing Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606, or experiencing symptoms like a rough idle, hesitation during acceleration, or incorrect transmission shifting, the PCM is a likely culprit. Our pre-programmed 2006 GMC Envoy PCM 12596784 is the definitive fix. We take the guesswork out of the repair by flashing the unit with your vehicle’s specific VIN and the latest GM software updates before it even ships. This ensures it communicates perfectly with your Envoy’s systems right out of the box, saving you a costly and time-consuming trip to the dealership.

An Expert’s Note on VIN Programming
Many people wonder why VIN programming is so critical. In vehicles like your 2006 Envoy, the PCM doesn’t just manage the engineโit’s part of a complex network that includes the anti-theft system (VATS/Passlock), transmission module, and instrument cluster. Simply installing a generic, un-programmed computer will cause a no-start condition or a cascade of communication errors. By programming the module to your specific VIN, we ensure all these components recognize each other and work together seamlessly, just as the factory intended. This is the key to a successful and lasting repair.
Frequently Asked Questions
Do I need to get this computer programmed?
No. We handle all the programming for you before shipping. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
What is a VIN and where do I find it?
The VIN is your 17-digit Vehicle Identification Number. It’s like a unique fingerprint for your Envoy. You can easily find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
This 2006 GMC Envoy PCM 12596784 is the correct solution for many issues that trigger a check engine light, especially internal module fault codes (like P0601). However, always ensure your vehicle has been properly diagnosed by a qualified mechanic, as other sensors or components could be at fault.
Is any other procedure needed after I install it?
In most cases, you will need to perform a simple security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This procedure is straightforward, requires no special tools, and we can provide you with easy-to-follow instructions.
How can I confirm this is the right part number for me?
The best way is to check the part number on the sticker of your original PCM. This unit is a direct replacement for part number 12596784 and all the other compatible numbers listed in the detailed fitment section.
