Restore Your Vehicle’s Brain, Restore Your Peace of Mind
Is your truck or van suffering from baffling issues like a persistent check engine light, erratic shifting, a rough idle, or even a no-start condition? The Powertrain Control Module (PCM) is the central computer of your vehicle, and when it fails, it can cause a cascade of frustrating problems. This isn’t just an inconvenience; for a work vehicle, it’s downtime that costs you money. This pre-programmed PCM is your direct-fit, dealership-free solution to get your vehicle back on the road and running with factory precision.
Common Symptoms & Your Solution
A failing PCM can be difficult to diagnose, but it often reveals itself through symptoms like poor fuel economy, hesitation during acceleration, or stalling. You may also have specific Diagnostic Trouble Codes (DTCs) stored, such as P0601 (Internal Control Module Memory Check Sum Error) or P0300 (Random/Multiple Misfire). Instead of chasing down individual sensors, address the core issue. This module, precisely programmed for your specific 1999-2002 Savana 3500 PCM requirements, is engineered to resolve these complex electronic issues and restore dependable operation.

Expert Insight: The Power of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicles with hard-to-solve running problems that all traced back to a faulty or incorrectly programmed PCM. On these GM Vortec engines, the PCM controls everything—from the precise moment of fuel injection to the firmness of a transmission shift. Simply installing a used module from another vehicle won’t work; it needs to be matched to your VIN and all its specific options. Our process ensures every parameter is set correctly, preventing the kind of electronic gremlins that can keep a vehicle off the road for weeks.
Getting your truck or van back in service is our top priority. By providing us with your VIN at checkout, you ensure that the 1999-2002 Savana 3500 PCM you receive is perfectly matched to your vehicle’s specifications. This critical step is the key to a smooth, successful repair that gets the job done right the first time.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), often called an Engine Control Module (ECM), is your vehicle’s main computer. It controls all aspects of engine and transmission function to ensure optimal performance, fuel economy, and emissions.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to work in your vehicle.
Is any additional programming needed after installation?
In most cases, no. The module is sent ready to install. However, some GM vehicles may require a simple, key-on security relearn procedure that takes about 10-15 minutes to perform and does not require any special tools. Instructions can be provided if necessary.
How can I be sure this fits my vehicle?
Please review the detailed fitment list provided on this page. This module is a direct replacement for multiple part numbers, including 16263494. The most crucial step is providing your VIN, which allows us to program it specifically for your truck or van, guaranteeing compatibility.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (like a P0601 code), this part is the correct solution. However, if the light is on due to a faulty sensor or other mechanical issue, that separate problem will still need to be addressed.
