Restore Peak Performance to Your GMC Envoy XL
Is your 2002 GMC Envoy XL suffering from frustrating and unpredictable issues like a persistent check engine light, poor shifting, or a no-start condition?

An Expert’s Note on VIN Programming: Why is programming so critical? On your 2002 Envoy, the PCM is the brain that talks to everything—the engine, transmission, anti-lock brakes, and even the security system (Passlock). A generic, non-programmed module simply won’t work. By flashing it to your exact VIN, we ensure all these systems communicate correctly, just as they did from the factory. This crucial step prevents a host of issues and makes the installation process as simple as possible for you or your mechanic.
Don’t let a faulty computer keep your reliable Envoy XL off the road. This is your opportunity to restore its performance and your peace of mind with a quality, correctly programmed 2002 GMC Envoy XL PCM.
Frequently Asked Questions
Do I need to do anything after installing the PCM?
Yes. After installation, you will need to perform a security relearn procedure, also known as a VATS or Passlock relearn. This synchronizes the new PCM with your vehicle’s anti-theft system. The procedure is simple, takes about 30 minutes, and requires only your car key—no special tools are needed. We include instructions to guide you through the process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program or ship your module without it. You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard near the windshield.
Will this fix my specific problem?
This 2002 GMC Envoy XL PCM is the correct solution for issues directly caused by a failing computer module. While it resolves the common symptoms listed above, we always recommend proper vehicle diagnostics to confirm the PCM is the root cause before ordering. This ensures you get the right part the first time.

The part numbers listed (19210066, 12571178, etc.) are the most common for this vehicle. If your number is different, please contact us with your VIN and original part number. We can verify compatibility and ensure you receive the correct module for your Envoy XL.
Is this a new part?
