Expert Insight: Don’t Forget the Security Relearn!
As a seasoned tech, I’ve seen countless people install a new PCM and panic when the truck won’t start. Remember, your GM vehicle has a built-in anti-theft system (VATS/Passlock). After installing this new module, you MUST perform a simple ‘security relearn’ procedure. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this sequence three times. This allows your truck’s security system to recognize the new PCM. It’s a simple step that ensures a successful installation and prevents unnecessary troubleshooting.
Frequently Asked Questions
What exactly is a PCM?
The Powertrain Control Module (PCM) is the main computer in your vehicle. It controls all aspects of the engine and transmission, such as fuel injection, spark timing, and shift points, to ensure your truck runs efficiently and reliably.
Do I need to do anything after I install it?
Yes. While the module is programmed for your engine and options, you will need to perform a security relearn procedure (also known as VATS or Passlock relearn) so the vehicle’s anti-theft system recognizes the new computer. This is a simple procedure that you can do yourself and does not require special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is required for the programming process.
Will this fix my specific problem or check engine light?
This programmed 2001-2002 Silverado 2500 PCM is the solution for issues directly caused by a failing computer, including common internal failure codes like P0601. However, it’s crucial to properly diagnose your vehicle first, as other faulty sensors or wiring issues can cause similar symptoms.
Is this part difficult to install?
Physically replacing the PCM is straightforward. It’s typically located under the hood, under the battery tray on the driver’s side. The process involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. The most important step is performing the security relearn after installation.
