Restore Your Truck’s Reliability and Performance
Is your truck suffering from baffling issues like stalling, erratic shifting, a persistent check engine light, or a complete no-start condition? These frustrating problems often point to a failing Powertrain Control Module (PCM), the central computer of your vehicle. Don’t let a faulty module keep you sidelined. This meticulously prepared PCM is your direct-fit, straightforward solution to restore the smooth, dependable performance you rely on every day. We take the guesswork out of the repair by programming the unit specifically for your vehicle using your VIN, ensuring it’s ready for installation right out of the box. Regain the confidence of a worry-free drive and get your truck’s brain back in perfect working order.
Warning Signs and How to Overcome Them
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the definitive solution:
- ✔ Unexplained Check Engine Light illumination, often with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606.
- ✔ Harsh or unpredictable automatic transmission shifting.
- ✔ Engine stalling, stumbling, or rough idling for no apparent reason.
- ✔ A decrease in fuel economy that you can’t trace to other causes.
- ✔ The engine cranks but refuses to start, even with a good battery and fuel supply.
- ✔ Other modules on the vehicle (like the ABS or BCM) report a loss of communication with the PCM.
A Mechanic’s Story: The Ghost in the Machine
A customer brought in his 2000 Sierra, a truck he loved, with a problem that was driving him crazy. It would randomly stall at red lights. He’d already replaced the throttle position sensor and the idle air control valve, but the “ghost” remained. After hooking up my scan tool, I noticed the live data stream from the PCM would just… freeze for a split second before the stall. There were no codes. It was the computer itself glitching internally. We installed a VIN-programmed PCM, and the truck ran like it just rolled off the assembly line. It’s a powerful reminder that sometimes, the most complex problems have a simple, central solution: a healthy control module.
Guided Installation to Restore Peace of Mind
Replacing your PCM is a manageable job for a confident DIYer. With our pre-programmed module, you skip the expensive trip to the dealer. Follow these steps to get back on the road:
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most 1999-2000 GM trucks like the Silverado and Sierra, the PCM is located in the engine bay, on the driver’s side, underneath the battery tray. You will need to remove the battery to access it.
- Disconnect the Old Module: Carefully unplug the electrical harness connectors from the old PCM. These connectors have locking tabs that need to be released. Note their color and orientation.
- Swap the Modules: Unbolt the old PCM from its bracket and set it aside. Mount your new, pre-programmed module in its place.
- Reconnect and Power Up: Firmly plug the harness connectors into the new PCM. Re-install the battery and connect the negative battery terminal.
- Perform Security Relearn: Your vehicle may require a simple security relearn procedure to recognize the new PCM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine.

Frequently Asked Questions
Do I need to program this module?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN after purchase, and we will flash the module with the latest GM-certified software for your specific vehicle. It arrives ready to install.
Where do I find my VIN?
Your Vehicle Identification Number (VIN) can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is installation difficult for a DIYer?
For most individuals with basic hand tools and some mechanical experience, this is a very straightforward installation. The most important parts are disconnecting the battery first and ensuring the harness connectors are seated properly on the new module.
What is a security relearn, and will I need to do it?
A security relearn, or VATS relearn, synchronizes the new PCM with your vehicle’s anti-theft system. Most GM vehicles of this era require it. It’s a simple procedure that involves cycling the ignition key and does not require any special tools. We include instructions to guide you through it.
Will this fix my specific Check Engine Light code?
This PCM will resolve issues directly caused by an internal failure of the original module, including common codes like P0601 (Internal Control Module Memory Check Sum Error). However, if your check engine light is on due to a faulty sensor (like an O2 sensor), that sensor will still need to be replaced. This module fixes the ‘brain,’ not the ‘senses’.
