An Expert’s Note on GM Security Systems
“On these GM trucks and SUVs from the early 2000s, the PCM is a central part of the Passlock II or Passkey 3+ vehicle security system. Simply swapping a used computer from another vehicle will result in a no-start condition because the security data doesn’t match. That’s why our VIN-programming service is so essential. We don’t just load the engine software; we ensure the foundational data is correct so the module can properly ‘shake hands’ with the rest of your vehicle’s electronics after the relearn procedure. It’s the difference between a quick fix and a week of headaches.”
Take the guesswork out of your repair. By ordering a pre-programmed 2004-2005 Envoy XUV PCM, you are choosing a reliable, professional-grade solution that saves you time, money, and frustration. Provide us with your VIN at checkout, and we’ll handle the rest.
Frequently Asked Questions
Do I need to do anything after I install this PCM?
Yes. You will need to perform a simple security relearn procedure, which typically takes about 30 minutes and involves turning the key in the ignition. This allows the new PCM to sync with your vehicle’s anti-theft system. We can provide instructions for this simple process.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle registration and insurance documents.
Is this PCM guaranteed to fix my vehicle’s problem?
This module is guaranteed to be a fully functional, correctly programmed replacement for a faulty PCM. It will solve any issues directly caused by your old computer. However, it’s important to ensure your vehicle has been properly diagnosed, as other issues (like bad sensors or wiring) can sometimes mimic PCM failure.
What part numbers does this module replace?
This computer is a direct replacement for a wide range of part numbers, including 12573576, 12574976, 12577955, 12584593, 16255757, and 19210065, among others listed in the fitment guide.
