An Expert’s Note on GM’s Passlock/VATS Security
As a technician who’s worked on countless of these 90s GM trucks, I can’t stress this enough: you can’t just swap in a used computer from a junkyard. On these vehicles, the PCM is electronically tied to the security system (VATS or Passlock) and the specific VIN. An incorrect module will trigger the anti-theft system and prevent the engine from starting. Our VIN programming service correctly configures the module, bypassing this entire headache and making the installation process as simple as swapping the part.
Don’t let a faulty computer keep your reliable truck sidelined. This is the most straightforward and effective way to restore your vehicle’s core functionality. By providing us with your VIN upon purchase, you’re getting a component that is truly ready for your specific 1997 Chevy Express 1500 PCM requirements and a wide range of other GM models. Check the fitment list to confirm compatibility.
Frequently Asked Questions
Do I need to have this programmed by a dealer after I receive it?
Absolutely not. The main benefit of our service is that we handle all the programming for you before we ship. It will arrive ready to install, saving you time and the high cost of dealer programming.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). You can typically find this on your dashboard (visible through the windshield), on your driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How difficult is the installation process?
For most 1997 GM trucks and vans, the PCM is located in the engine compartment, often near the battery. It’s a straightforward job for a confident DIYer. You’ll need to disconnect the battery, unplug the electrical connectors, and unbolt the old module to swap in the new one. No special tools are typically required.
Will this fix my Check Engine Light?
If your Check Engine Light is on due to an internal fault with the original PCM (like a P0601 code), then yes, this part is the correct fix. However, it will not fix issues caused by other faulty components like sensors or wiring problems.
How do I provide my VIN after purchase?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. You can also send it to us through our website’s contact form, referencing your order number.
Does this fit other GM models besides the Express van?
Yes, this specific 1997 Chevy Express 1500 PCM is also the correct computer for a wide range of GM trucks and SUVs from that year, including the C/K 1500/2500/3500 pickups, Suburban, Tahoe, Yukon, and S-10/Blazer series. Please review the detailed fitment list on this page to be certain.
