Is your 2000 Chevrolet Tahoe, Silverado, or another compatible GM vehicle suffering from perplexing engine issues? A faulty Powertrain Control Module (PCM) is often the culprit behind problems like a persistent check engine light, poor fuel economy, stalling, or even a no-start condition. This replacement PCM, part number 9354896, is the definitive solution to restore your vehicle’s factory performance and reliability. As the central computer of your vehicle, the PCM manages critical functions of the engine and transmission, and when it fails, the symptoms can be widespread and frustrating.
We take the guesswork out of the repair process. Unlike a generic module from a salvage yard, this unit is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This crucial step ensures that the computer has the correct software and calibrations for your engine, transmission, and factory options. We flash it with the latest updates available from General Motors, which can often resolve issues that were present even when the vehicle was new. This means you receive a module that is ready for installation, simplifying the repair and getting you back on the road with confidence.
We had a 2000 Sierra 1500 come in with an intermittent stalling problem that was driving the owner crazy. It would die at stoplights, but not always. We checked fuel pressure, sensors, and wiring, but couldn’t find a consistent fault. After hours of diagnostics, we noticed the 5-volt reference signal to the sensors would occasionally drop out. We connected a scope to the PCM outputs and confirmed the module itself was failing internally under certain conditions. We installed one of our VIN-programmed PCMs, performed the security relearn, and the truck ran perfectly. The customer was thrilled to have his reliable truck back without the constant fear of stalling in traffic.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is your vehicle’s main computer. It controls all aspects of engine and transmission operation to ensure optimal performance, fuel economy, and emissions.
Is this part ready to install?
Yes, this module is shipped to you pre-programmed to your vehicle’s VIN. After installation, you may need to perform a simple security relearn procedure (often called a ‘key-on/key-off’ cycle) to sync the module with your vehicle’s anti-theft system. Instructions for this are widely available online.
How do I provide my VIN?
After placing your order, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty PCM, this replacement will resolve the issue. However, it’s always best to have the codes professionally diagnosed to ensure the problem isn’t with a sensor or other component that the PCM is monitoring.
Where is the PCM located on my 2000 Tahoe?
On the 2000 Tahoe and similar GM trucks like the Silverado and Sierra, the PCM is typically located in the engine bay on the driver’s side, mounted to a bracket below or near the battery tray.
