Effortless Steps for a Confident Fix
Replacing your 2001-2002 Chevrolet 3500 PCM is a straightforward job you can tackle with basic tools. Follow these guided steps to restore your truck’s health and get back to what matters.
- Safety First: Begin by disconnecting the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: You’ll find the PCM located on the driver’s side of the engine bay, typically under or next to the battery tray.
- Disconnect Wiring: Carefully unplug the electrical harness connectors from the old PCM. There are usually release tabs that you’ll need to press or lift. Avoid pulling on the wires themselves.
- Remove the Old PCM: Unbolt the mounting hardware that secures the old computer to its bracket and remove it from the vehicle.
- Install the New Unit: Mount your new, pre-programmed PCM in the same location, securing it with the original hardware.
- Reconnect and Finalize: Firmly plug the wiring harnesses into the new module until they click into place. Reconnect the negative battery terminal. In some cases, a security relearn procedure may be necessary, which typically involves cycling the key.
Expert Diagnostic Tip
Before condemning your PCM, take a moment to inspect your battery terminals and the main engine ground wires. A loose, corroded, or failing connection can cause erratic voltage, which often mimics the symptoms of a bad computer. A simple cleaning and tightening can sometimes save you a lot of diagnostic headaches. A healthy electrical foundation is key to a reliable truck.

Where do I provide my VIN?

What is the security relearn procedure?
For some GM vehicles, the anti-theft system (Passlock/VATS) needs to sync with the new PCM.

Instructions are readily available online for your specific model.
