Restore Your Vehicle’s Heartbeat and Performance
Is your Corvette, Camaro, or Silverado suddenly acting up? A flickering check engine light, erratic shifting, or a frustrating no-start condition can quickly turn a pleasant drive into a stressful ordeal. These aren’t just annoyances; they’re often symptoms of a failing Powertrain Control Module (PCM), the central computer that manages your engine and transmission. This replacement PCM, part number 09354896, is the definitive solution to bring back the smooth, reliable performance you depend on. We take the guesswork out of the repair by programming the module specifically to your vehicle’s VIN before it even leaves our facility, ensuring a straightforward, plug-and-play installation.
Warning Signs Your PCM Needs Attention
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, this module is the reliable fix you’ve been looking for:
- ✔ Check Engine Light: Persistent illumination, especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, rough idling, or sudden stalling.
- ✔ Reduced Fuel Economy: An unexplained drop in MPG is a common sign the PCM isn’t managing the fuel system correctly.
- ✔ Erratic Transmission Shifting: Harsh, delayed, or unpredictable gear changes can point directly to a faulty computer.
- ✔ Intermittent Starting Issues: The vehicle cranks but refuses to start, or starts unreliably, often without a clear pattern.
- ✔ Communication Failures: Your diagnostic scan tool is unable to connect with the PCM, indicating an internal module failure.
An Expert’s Story: The Elusive Stumble
“A customer brought in his 2000 Silverado 2500 with a problem that had stumped two other shops. It had a random, intermittent stumble under light load—no codes, no consistent pattern. We checked everything: fuel pressure, ignition components, sensors. Everything looked perfect. On a hunch, I monitored the live data stream from the PCM. I noticed the injector pulse width would flicker erratically right before the stumble. The computer’s internal processor was failing under specific conditions. We installed a VIN-programmed PCM, and the truck ran like it just rolled off the assembly line. It’s a powerful reminder that the PCM is the brain, and when it’s not healthy, the whole system suffers.”

Getting Your Ride Back on the Road: A 1999-2000 Corvette PCM Installation Guide
Replacing your PCM is a manageable job that you can tackle with basic hand tools and confidence. Our pre-programmed module eliminates the need for expensive dealer visits. Follow these steps for a successful installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental electrical shorts.
- Locate the Old PCM: On most compatible vehicles like the Corvette or Camaro, the PCM is located in the engine compartment, often behind the right-hand strut tower or under the battery tray on trucks and SUVs. Consult your vehicle’s service manual for the exact location.
- Disconnect the Harnesses: Carefully disengage the locking tabs on the electrical connectors. They can be stiff, so use gentle, steady pressure. Never pull on the wires themselves. Inspect the connectors for any corrosion or bent pins.
- Remove the Module: Unbolt the PCM from its mounting bracket. Keep the hardware safe, as you’ll need it to install the new unit.
- Install the New PCM: Mount your new, VIN-programmed module securely onto the bracket. Reconnect the electrical harnesses, making sure you hear a solid ‘click’ as they lock into place.
- Reconnect the Battery: Re-attach the negative battery terminal and tighten it securely.
- Perform Security Relearn (If Necessary): Some GM vehicles require a simple security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Your vehicle’s manual will have the specific steps. Once complete, your vehicle is ready to start.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you. Simply provide us with your vehicle’s 17-digit VIN during checkout, and we will flash the module with the latest GM-certified software for your specific vehicle. It will arrive ready to install.
What is a VIN and where can I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can typically find it on a plate on the driver’s side 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 specific problem?
This module is the definitive solution for issues caused by a failing PCM, including common DTCs, poor performance, and no-start conditions. While it resolves the vast majority of computer-related problems, we always recommend a proper diagnosis to rule out other potential causes like faulty sensors or wiring.
Is a security relearn procedure difficult?
Not at all. The GM Passlock/VATS security relearn is a simple key-cycle procedure that you can do yourself in about 30 minutes with no special tools. We include instructions, and it’s a straightforward process designed to sync the new PCM with your vehicle’s anti-theft system.
What if my original part number is slightly different?
This module is a compatible replacement for several part numbers, including 19109040 and 9354896. As long as your vehicle’s year, make, and model are on our compatibility list, this programmed 1999-2000 Corvette PCM will function correctly as the hardware is designed to serve multiple applications once programmed.
