Restore Peak Performance to Your GM Vehicle
Is your 1999-2002 Camaro, Firebird, or GM truck suffering from baffling electrical gremlins? Issues like random stalling, a persistent check engine light, or a complete no-start condition often point to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s the central computer of your vehicle, and when it falters, everything from fuel delivery to transmission shifting can be compromised. This replacement PCM, part number 09354896, is the definitive solution to restore your vehicle’s factory operation and reliability.
We take the guesswork and hassle out of the repair. Unlike sourcing a used part with an unknown history, this module is delivered to you fully programmed with the latest official GM software. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will flash the computer specifically for your car or truck. This ensures seamless communication between all vehicle systems and eliminates the need for an expensive trip to the dealership for programming. It’s the most direct path to getting your vehicle back on the road and running as it should.
Case Study: A Tricky Diagnosis
I remember a 2001 Camaro SS that came into the shop with a frustratingly intermittent no-start condition. The owner had already replaced the battery and checked the fuel pump. When it acted up, the security light would flash, but it wouldn’t store any consistent trouble codes. We spent hours checking wiring and grounds. Finally, on a hunch, we monitored the PCM’s internal temperature data. We discovered that once the module reached operating temperature, it would develop an internal short, causing it to lose communication with the Body Control Module and trigger the security system. Swapping in a pre-programmed 1999-2002 Camaro PCM like this one solved the problem instantly. It’s a perfect example of how a failing computer can create symptoms that mimic other component failures.
Common Signs of a Failing Powertrain Control Module
If you’re experiencing any of the following, a faulty PCM could be the culprit. I’ve seen these symptoms countless times in my 20+ years of diagnostic work.
- ✔ Your vehicle fails to start or starts intermittently.
- ✔ Unexplained stalling while driving or at idle.
- ✔ A persistent Check Engine Light, especially with communication error codes.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0601, P0602, or P0606.
- ✔ Poor fuel economy and noticeable loss of power.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Multiple, unrelated sensor codes appearing at the same time.
A Straightforward Guide to Installation
Installing your new PCM is a manageable job for a DIYer with basic tools. The location varies between F-body cars and trucks, but the process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On a Camaro or Firebird, it’s typically behind the passenger-side strut tower in the engine bay. On Silverado/Sierra trucks and SUVs, it’s usually under the hood on the driver’s side, often below the battery tray.
- Disconnect the Old Module: Carefully unplug the electrical harness connectors. They have locking tabs that need to be released—don’t force them.
- Remove the PCM: Unbolt the module from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed module in place and securely fasten it.
- Reconnect Everything: Plug the harness connectors in firmly until they click. Reconnect the negative battery terminal.
- Perform Security Relearn: On many of these GM vehicles, you will need to perform a simple key-cycle security relearn procedure. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. This allows the new PCM to recognize your vehicle’s key.

Frequently Asked Questions
Frequently Asked Questions
Why is my VIN required for programming?
Your Vehicle Identification Number (VIN) allows us to load the exact GM-specified software for your vehicle’s engine, transmission, and options. This ensures perfect compatibility and function, just like a part from the dealer, without the high cost.
Is this a simple plug-and-play installation?
Yes, because we program it beforehand. Once installed, you will likely need to perform a standard security relearn procedure, which involves a few key cycles and takes about 30 minutes. This does not require any special tools.
What if my original part number is 19109040?
This module is a fully compatible replacement for part numbers 19109040 and 9354896. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (like code P0601), then yes, this part will resolve the issue. It’s crucial to properly diagnose the vehicle first, as the light can also be triggered by faulty sensors or other components.
Is this the correct computer for my 2001 Camaro with ID 9354896?
Yes, absolutely. This PCM is the specified replacement for vehicles that originally came with the module identified as 9354896. We will ensure it is programmed correctly for your specific year and model.
