When your 2001-2002 GMC Savana 3500 is down, your work stops. Unreliable starting, poor fuel economy, and a persistent Check Engine Light are more than just annoyances—they cost you time and money. Restore your van’s core operational integrity with this Powertrain Control Module (PCM), the central command unit for your engine and transmission. This isn’t just a replacement part; it’s a direct-fit, VIN-programmed solution designed to get your workhorse back on the road with minimal downtime.
Is Your Savana 3500 Showing Signs of a Bad PCM?
A failing PCM can cause a wide range of confusing and intermittent issues. If you’re experiencing any of the following, a faulty engine computer could be the culprit:
- Check Engine Light: Especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606.
- No-Start or Hard-Start Condition: The engine cranks but refuses to start, or only starts after multiple attempts.
- Rough Idle & Stalling: The engine runs erratically, shakes, or stalls unexpectedly at stops.
- Poor Fuel Economy: A sudden and unexplained drop in your van’s miles per gallon.
- Failed Emissions Test: Inability to pass state inspection due to module-related faults.
This module is the definitive solution, arriving pre-programmed to your specific vehicle to restore communication between all critical systems and ensure your engine operates exactly as the manufacturer intended.

From Our Experts: Protect Your New Module
Before installing your new PCM, take a moment to inspect and clean your vehicle’s main grounding points. A poor ground connection at the chassis or engine block can create voltage spikes that damage sensitive electronics. Ensuring these connections are clean, tight, and free of corrosion is a simple step that protects your investment and ensures a lasting, reliable repair.
Frequently Asked Questions
Do I need to program this module after I receive it?
No. This module is fully pre-programmed to the VIN you provide after your purchase. It is designed for a plug-and-play installation. In some cases, a CASE (Crankshaft Angle Sensor Error) relearn procedure may be needed with a scan tool to clear a related code, but the core programming is complete.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
What’s the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. ECU (Engine Control Unit) is a general term. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module), like this unit, is more comprehensive and manages both the engine and the automatic transmission functions.
Will this PCM fix my vehicle’s problem for sure?
This module will correct any issues caused by an internal failure of the original PCM. However, it is crucial that your vehicle has been properly diagnosed. This part will not fix problems caused by other faulty components, such as a bad sensor, a wiring short, or a failing fuel pump.
Is this compatible with other GM trucks and vans?
Yes, this PCM is compatible with a wide range of 2000-2003 GM vehicles, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Express van. Please check the detailed fitment list on this page to confirm it matches your specific model and engine.
