Restore Your Vehicle’s Core Performance and Reliability
Is your Corvette, Camaro, or Silverado suffering from frustrating issues like stalling, erratic shifting, a persistent Check Engine Light, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine’s performance. As a technician with over two decades of experience, I’ve seen firsthand how a faulty PCM can cripple an otherwise healthy vehicle. This isn’t just a part; it’s the brain of your engine’s operation, and when it fails, you need a solution you can trust.
This replacement PCM, part number 09354896, is the definitive fix. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s Vehicle Identification Number (VIN) before we ship it. This critical step ensures all factory settings and vehicle-specific options are correctly loaded, making the installation process as simple as possible. It arrives loaded with the latest GM software updates, often resolving underlying drivability issues that older software couldn’t. This is the same level of service you’d get at a dealership, without the high cost or inconvenience.
A Technician’s Notebook
I remember a 2000 Silverado 2500 that came into the bay with a maddeningly intermittent no-start condition. The owner had already replaced the battery, starter, and fuel pump. It would run fine for days, then refuse to start, only to fire right up an hour later. No codes were stored. After checking all the grounds and power feeds to the PCM, I noticed the failure only happened on hot days after the truck had been sitting in the sun. On a hunch, I used a heat gun on the PCM, and sure enough, the engine died. A hairline crack on the circuit board was expanding with heat, breaking the connection. Replacing the PCM with a properly programmed unit solved the problem for good. It’s a perfect example of how PCM failure isn’t always a simple code—it can be a tricky ghost in the machine.
Is Your Vehicle Showing These Symptoms?
A failing engine computer can manifest in numerous ways. If you’re experiencing any of the following, a faulty PCM is a likely culprit. This is especially true if you see diagnostic trouble codes (DTCs) related to internal module failure.
- ✔ Check Engine Light is on with codes like P0601, P0602, P0604, or P0606 (Internal Control Module Memory/Processor Errors).
- ✔ The engine cranks but will not start.
- ✔ Unexplained drops in fuel economy.
- ✔ The transmission is shifting harshly or at the wrong times.
- ✔ Intermittent stalling or rough idling for no apparent reason.
- ✔ Communication errors with your scan tool.
A Straightforward Guide to Installation
Replacing your 1999-2000 Corvette PCM or the computer in a compatible GM truck is a job most DIYers can handle. Our VIN programming service eliminates the most difficult step. Just follow this general process:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for the system capacitors to discharge.
- Locate the PCM: The location varies. On a C5 Corvette, it’s in the engine compartment on the passenger side. On Silverado/Sierra trucks, it’s typically under the hood on the driver’s side, below or near the battery. On F-Body cars (Camaro/Firebird), it’s behind the passenger-side strut tower.
- Disconnect the Connectors: Carefully unclip and remove the wiring harness connectors from the old PCM. They are often color-coded. Inspect them for any corrosion or damaged pins.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed PCM into place. Reconnect the wiring harnesses, ensuring they click securely into position.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn (If Necessary): On many GM vehicles, you will need to perform a simple security relearn procedure so the vehicle recognizes the new PCM. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. Your vehicle’s service manual will have the exact steps.

How do I provide my VIN for programming?
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for programming the module correctly for your vehicle’s specific configuration.
Is this part difficult to install?
No, this is a plug-and-play repair for most individuals with basic mechanical skills. Since we handle the programming, you will not need any special scan tools. The main steps are disconnecting the battery, swapping the module, and performing a simple key-cycle security relearn procedure, which takes about 30 minutes.
Will this fix my Check Engine Light?
If your Check Engine Light is on due to an internal PCM failure (like codes P0601-P0606), then yes, this part is the correct fix. However, if the light is on for another reason, such as a bad oxygen sensor or an EVAP leak, this will not resolve that specific issue. Proper diagnosis is key.
What if I have modifications on my vehicle?
Our programming service installs the latest stock GM calibration for your VIN. It is not designed to account for significant aftermarket modifications like different injectors, camshafts, or forced induction. This module is intended for vehicles with stock or near-stock configurations.
Does this module come with a warranty?
Yes, all of our electronic modules are thoroughly tested and come with a warranty. Please see the warranty tab on this listing for complete details and peace of mind with your purchase.
