We understand that you need a reliable, straightforward solutionโfast. This is the definitive replacement for your faulty computer, designed to restore your van’s performance and get you back to work with confidence.
This unit is a direct-fit replacement, but it’s more than just a part. We professionally program it to your van’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures it communicates flawlessly with your vehicle’s systems, just like the original, but with the benefit of the latest GM software updates. By handling the programming for you, we eliminate the need for an expensive trip to the dealership, saving you both time and hassle. This is the most efficient way to solve your PCM problems and ensure your 2001-2002 Savana 3500 PCM is functioning perfectly.
Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing any of the following, a faulty engine computer is the likely culprit:
- The Check Engine Light is on with communication-related codes (e.g., P0601, P0605).
- Your van experiences random stalling or difficulty starting.
- Noticeable decrease in fuel economy.
- Harsh or unpredictable automatic transmission shifting.
- The engine runs rough, misfires, or lacks power.
- Your scan tool cannot communicate with the PCM.
This pre-programmed module is engineered to resolve these issues, restoring the precise engine and transmission control your Savana needs to operate reliably day in and day out.

Expert Mechanic’s Tip: The Anti-Theft Relearn Procedure
While we handle the complex programming, your van’s anti-theft system (Passlock/VATS) needs to sync with the new PCM after installation. This is a simple procedure you can do yourself in about 30 minutes with just your key. It typically involves turning the key to the ‘ON’ position for 10 minutes, off for 10 seconds, and repeating this sequence three times. This final handshake between the components is crucial and ensures your van will start and run correctly. We include simple, step-by-step instructions to make this process foolproof.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the critical programming based on your VIN. The only thing you may need to do is a simple key-cycle “security relearn” procedure, which takes about 30 minutes and requires no special tools. We provide clear instructions for this.
Where do I provide my VIN?
After you complete your purchase, you can either send us a message with your 17-digit VIN or add it to the ‘notes’ section during checkout. We cannot ship your order until we receive your VIN, as the programming is essential.
Is this 2001-2002 Savana 3500 PCM compatible with other vehicles?
Yes, this computer is a workhorse for GM and fits a wide range of trucks and vans from that era, including the Silverado 1500/2500/3500, Sierra, Express Van, Tahoe, Yukon, and Suburban, among others. The key is matching the part number and ensuring we program it for your specific vehicle.
What tools are needed for installation?
Installation is straightforward for anyone with basic mechanical skills. You will typically need a socket set (often 10mm and 13mm sockets), a ratchet, and a flathead screwdriver. Always disconnect the negative battery terminal before starting work.
How do I know for sure my original PCM has failed?
Common signs include a persistent Check Engine Light with internal processor error codes (like P0601), a no-start condition where the engine cranks but won’t fire, or a complete loss of communication with a diagnostic scan tool. If you’re experiencing several of these symptoms, the PCM is the most likely cause.
What if I have a problem after installation?
First, ensure the security relearn procedure was completed correctly. If issues persist, please contact our support team. This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
