Get Your Workhorse Back on the Road
When your 2001-2002 GMC Savana 3500 is down, your work stops. A faulty Powertrain Control Module (PCM) can cause a cascade of frustrating issues, from erratic engine behavior to a complete no-start condition. Don’t let a bad computer keep your van sidelined. This professionally programmed PCM is the reliable, straightforward solution to restore your vehicle’s factory performance and get you back to work with confidence.
Is Your GM Truck or Van Showing Signs of a Bad PCM?
A failing engine computer can manifest in various ways, often leading to incorrect diagnostics and costly, unnecessary repairs. If your vehicle is experiencing any of the following, a faulty PCM could be the culprit:
- Check Engine Light: The light is on, and you may have codes like P0601, P0602, or P0606 stored.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, or decreased fuel economy.
- Erratic Shifting: The transmission may shift harshly, at the wrong times, or not at all.
- Stalling or Rough Idle: The engine stalls intermittently, especially when stopping, or idles roughly.
- No-Start Condition: The engine cranks but will not start, and you’ve ruled out fuel and spark issues.
- Communication Errors: Your diagnostic scan tool cannot communicate with the PCM.
This module is the definitive solution. We program it with the latest official GM software updates using your vehicle’s VIN, ensuring it functions correctly right out of the box and seamlessly integrates with your van’s systems.

An Expert’s Note on Installation
A common oversight during PCM replacement is failing to address the original cause of failure. Before installing your new module, we strongly recommend inspecting the wiring harness for any chafed or shorted wires, particularly around the module’s mounting location. Also, ensure your battery terminals are clean, and the grounds are secure. A clean installation environment and a solid electrical foundation are key to the long-term health of your vehicle’s new brain.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM comes fully programmed to the VIN you provide. The only additional step that may be required is a simple security relearn procedure, which pairs the module to your existing keys. This process takes about 10-15 minutes and does not require any special tools.
Where do I provide my vehicle’s VIN?
You can add your 17-digit VIN in the notes section during checkout. If you forget, we will contact you via email to request it before we can program and ship your module.
Will this fix my specific problem?
This module will correct any issues directly caused by a failing PCM. However, it is crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical failures.
Is a CASE (Crankshaft Angle Sensor Error) relearn required?
In most cases for this vehicle generation, a CASE relearn is not required for the vehicle to run and drive properly. However, for optimal performance and to clear a potential check engine light for code P1336, a CASE relearn with a capable scan tool is recommended after installation.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Electronic Control Unit) is a general term. ECM (Engine Control Module) typically controls only the engine. A PCM (Powertrain Control Module), like this unit, is more integrated and controls both the engine and the transmission functions.
Does this module come with new keys?
No, this module does not include keys. It is programmed to work with your vehicle’s existing keys after you perform the simple, tool-free security relearn procedure upon installation.
