Expert Insight: The Importance of VIN Programming
For these late-90s GM trucks, the PCM is more than just an engine controller; it’s the central command for the entire vehicle. It’s directly tied into the anti-theft system (VATS/Passlock). Simply installing a used computer from another truck will almost always result in a no-start security lockout. That’s why our VIN programming service is not just a convenience—it’s a necessity. We’re not just selling you a part; we’re providing a complete, ready-to-install solution that bypasses the headaches and gets your reliable workhorse back on the road.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. All you need to do is provide us with your vehicle’s 17-digit VIN during or after checkout. The only step you may need to perform after installation is a simple security relearn procedure, which takes about 10-15 minutes and requires only your ignition key.
What is the security relearn procedure?
After installing the PCM, you may need to help your vehicle recognize it. The procedure is typically: 1) Turn the key to the ‘ON’ position (don’t start the engine). 2) Leave it on for 10 minutes, or until the ‘Security’ light on the dash stops flashing and turns off. 3) Turn the key off for 5 seconds. 4) The vehicle should now start. We include simple instructions with your order.
Is this a new part?
No, this is a high-quality, inspected, and tested used part that has been sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution for your 1999 Suburban 1500 PCM replacement needs.
How do I find my part number to confirm a match?
Your vehicle’s original PCM is typically located in the engine bay, often on the driver’s side fender. The part number is printed on a sticker on the module itself. You can match it to the numbers listed in our description, such as 09355699 or 9366810.
Will this fix my specific problem?
This part is a solution for a faulty PCM. While it resolves a wide range of common electronic and drivability issues, it’s important to ensure your vehicle has been properly diagnosed. This module will not fix problems related to bad sensors, faulty wiring, or mechanical failures.
