Restore Your Truck’s Brainpower and Performance
Is your 2000 Suburban 2500 suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM) is often the hidden culprit behind problems that can leave you stranded. As the central computer for your engine and transmission, a failing PCM can cause everything from a simple check engine light to a complete no-start condition. I’ve seen it hundreds of times in the shop: a vehicle comes in with baffling symptoms that all trace back to this single component. This isn’t just a replacement part; it’s a direct solution to restore your vehicle’s reliability and drivability.
This module is the definitive fix for your GM truck or SUV. We take the guesswork and hassle out of the repair by pre-programming this PCM specifically to your vehicle’s VIN. This means it arrives at your door with the latest GM factory software updates already installed. You get the benefit of improved performance parameters and fixes for common factory bugs, all without a costly trip to the dealership. Simply provide your VIN after purchase, and we’ll handle the complex programming for you.
From the Diagnostic Bay: The Intermittent Stall Case
A customer brought in a 2000 Silverado 2500 with a problem that was driving him crazy. The truck would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. No consistent check engine light, just random, intermittent failure. We checked fuel pressure, ignition components, and sensors—all tested fine. After hooking up a high-end scanner and monitoring live data, we finally caught it: the PCM was momentarily losing communication and dropping all its outputs. It was a classic case of internal circuit board failure due to heat and age. We installed a VIN-programmed PCM just like this one, and the truck has been running flawlessly ever since. These intermittent issues are often the clearest sign of a failing computer.
Common Signs of a Failing PCM
- ✔ Check Engine Light is on with communication error codes (e.g., P0601, P0606).
- ✔ Engine cranks but will not start.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Other modules on the vehicle (like the ABS or BCM) cannot communicate with the PCM.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- ✔ Locate the PCM: On most compatible trucks and SUVs (like the Suburban, Silverado, and Sierra), the PCM is located in the engine bay on the driver’s side, typically under or next to the battery tray.
- ✔ Disconnect Connectors: Carefully unclip and remove the electrical wiring harnesses from the old PCM. These connectors have locking tabs that need to be released before pulling.
- ✔ Remove the Old Module: Unbolt the PCM from its mounting bracket. Keep the hardware, as you may need to reuse it.
- ✔ Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and securely fasten it.
- ✔ Reconnect Everything: Plug the wiring harnesses firmly into the new module until they click into place. Reconnect the negative battery terminal.
- ✔ Final Step: In some cases, a security or CASE relearn procedure may be necessary with a capable scan tool to sync the new PCM with your vehicle’s anti-theft and crankshaft position sensor systems.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to the VIN you provide before we ship it. It arrives ready for installation, loaded with the latest GM software for your vehicle.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
What is a CASE relearn and will I need one?
A Crankshaft Variation (CASE) relearn synchronizes the PCM with the crankshaft position sensor. While many vehicles will start and run without it, performing a CASE relearn with a compatible scan tool is recommended for optimal performance and to prevent a P1336 trouble code.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part that has been professionally programmed to ensure it meets or exceeds original factory performance standards.
What if my part number is slightly different?
This module directly replaces part numbers 09354896, 19109040, and 9354896. If your part number matches one of these, it is the correct part for your vehicle, provided your model is on the compatibility list.
