Get Your Workhorse Back on the Job, Fast.
A non-starting van or a persistent check engine light isn’t just an annoyanceโit’s costing you time and money. When the brain of your vehicle, the Powertrain Control Module (PCM), starts to fail, it can cause a host of frustrating and debilitating issues. This replacement module is the definitive, hassle-free solution to restore your vehicle’s performance and reliability. We provide a professionally programmed 2001-2002 Savana 2500 programmed PCM that arrives at your door ready for installation, getting you back on the road without an expensive trip to the dealership.
Common Symptoms & Your Solution
If your truck or van is experiencing any of the following, a failing PCM is the likely culprit:
- Check Engine Light: Particularly for codes like P0601, P0602, P0604, or P0606, which indicate internal module failure.
- No-Start or Hard-Start: The engine cranks but refuses to start, or only starts after multiple attempts.
- Poor Performance: Noticeable loss of power, rough idling, stalling, or decreased fuel economy.
- Erratic Shifting: The transmission may shift harshly, incorrectly, or not at all.
- Failed Emissions Test: An unresponsive module can prevent your vehicle from passing inspection.
This module is the solution. By replacing your faulty unit with this pre-flashed computer, you are directly addressing the root cause of these problems and restoring your vehicle’s factory-specified operation.

Expert Insight: The Dreaded P0601 Code
As a technician, one of the most definitive trouble codes is P0601: “Internal Control Module Memory Check Sum Error.” In simple terms, this means the PCM has failed its own internal integrity test. It’s like a computer that can’t read its own hard drive. There is no software fix or reflash that can correct this; the internal hardware is compromised. When you see this code, replacement is the only reliable path forward. Installing a quality, correctly programmed 2001-2002 Savana 2500 programmed PCM is the direct and permanent fix to clear this code and restore vehicle health.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the module. You just need to provide us with your vehicle’s VIN at checkout. The module will arrive ready for installation.
Will I need to perform a security relearn procedure?
For many GM vehicles of this era, a security relearn (often called a Passlock or VATS relearn) is necessary after installation. This procedure syncs the new PCM with your vehicle’s anti-theft system. It’s a simple process that typically takes 10-30 minutes and does not require any special tools. We include instructions to guide you through it.
How do I provide my VIN?
You can enter your 17-digit Vehicle Identification Number (VIN) during the checkout process. Please double-check it for accuracy, as this is critical for correct programming.
Is this a guaranteed fix for my vehicle’s problems?
This 2001-2002 Savana 2500 programmed PCM will correct all issues directly caused by a faulty module. While it solves the vast majority of the symptoms listed above, it’s always important to ensure your vehicle has been properly diagnosed. This part will not fix problems related to other faulty sensors or mechanical issues.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
Where is the PCM located on my vehicle?
On most compatible trucks and SUVs (Silverado, Sierra, Tahoe), the PCM is located under the hood on the driver’s side, often under the battery tray. On vans (Express, Savana), it’s typically found in the rear of the engine compartment on the driver’s side. Always disconnect the battery before attempting removal or installation.
