An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money on generic, unprogrammed modules. Your vehicle’s PCM is not a one-size-fits-all part. It needs to know your specific engine, transmission, tire size, and factory options to operate correctly. Our mandatory VIN programming service isn’t an upsell; it’s the critical step that ensures your 2002 Envoy XL PCM works flawlessly the moment you install it. We’re not just selling you a part; we’re delivering a complete, reliable solution.
Frequently Asked Questions
Do I need to do anything after installing the PCM?
In most cases, you will need to perform a simple security relearn procedure, also known as a CASE relearn. This can typically be done without special tools and involves a sequence of key turns. We include instructions to guide you through this quick process.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot ship your order until we receive the VIN, as programming is a required step.
Will this fix my specific problem?
This 2002 Envoy XL PCM is the correct solution for failures of the engine computer itself. While it resolves the most common electronic issues, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential problems like faulty wiring or sensors.
Is this a brand new computer?
This is a high-quality, OEM replacement unit that has been thoroughly inspected, tested, and prepared to meet or exceed original factory specifications. It is loaded with the newest software available for your vehicle.
What does the one-year replacement warranty cover?
The warranty covers any functional failure of the module itself for a period of one year from the date of purchase. If the unit fails, we will provide a replacement. The warranty does not cover issues caused by other vehicle faults, such as electrical shorts or improper installation.
