Restore Peak Performance to Your GM Vehicle
Is your 1999-2002 Firebird, Camaro, or GM truck suffering from erratic behavior, poor fuel economy, or a persistent Check Engine light? These are classic signs of a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, a faulty PCM can cause a cascade of frustrating and difficult-to-diagnose issues. This replacement module, part number 09354896, is the definitive solution to restore your vehicle’s factory performance, reliability, and drivability.
Unlike generic modules from a salvage yard, this unit is professionally programmed specifically for your vehicle. Upon purchase, you simply provide us with your Vehicle Identification Number (VIN). Our technicians then flash the module with the latest, most stable General Motors software updates available for your exact make and model. This critical step ensures seamless communication between all vehicle systems, corrects potential factory flaws, and guarantees optimal engine and transmission function right out of the box.
Diagnosing a Defective 1999-2002 Firebird PCM
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your PCM is a likely culprit. Verifying these symptoms can save you time and money on unnecessary repairs.
- ✔ Check Engine Light: The most common indicator, often with communication-related codes (U-codes) or multiple, seemingly unrelated sensor codes.
- ✔ No-Start or Hard-Start Condition: The engine may crank but fail to start, or take an unusually long time to fire up, due to incorrect fuel or spark commands.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, stumbling, or misfiring as the PCM struggles to manage the engine.
- ✔ Reduced Fuel Economy: An inefficiently running engine, caused by incorrect air/fuel mixture calculations from a faulty module, will consume more fuel.
- ✔ Harsh or Erratic Shifting: The PCM also controls the transmission. A failing unit can cause delayed shifts, banging into gear, or failure to shift at all.
- ✔ Intermittent Stalling: The vehicle may stall unexpectedly while driving or at idle for no apparent reason.
- ✔ Failure to Communicate with Scan Tools: If your diagnostic scanner cannot connect to the vehicle’s computer, it’s a strong sign the PCM itself has failed.
A Simple, Reliable Solution
Replacing your vehicle’s PCM shouldn’t be a gamble. Our process is designed to be straightforward and effective. We take a high-quality, tested hardware unit and program it to your specific VIN. This ensures that all factory settings, including engine parameters, transmission strategy, and security information, are a perfect match for your vehicle’s original configuration. This module is a direct replacement for part numbers 09354896, 9354896, and 19109040.
Installation Note: After installing the new PCM, a security relearn procedure (often called VATS or Passlock relearn) will be necessary. This procedure pairs the new module to your vehicle’s anti-theft system and keys. It is a simple process that typically takes 30 minutes and can be done without special tools. Instructions are widely available online or in your vehicle’s service manual.
Broad GM Compatibility
While this is a popular part for the F-Body platform (Camaro and Firebird), this versatile PCM was used across a wide range of GM trucks and SUVs from 1999 to 2002. Please verify your original part number and consult the fitment list below to ensure compatibility with your vehicle.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission operation, including fuel injection, ignition timing, emissions systems, and shift points, to ensure optimal performance and efficiency.
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) contains specific information about your car’s engine, transmission, emissions, and other options. We use the VIN to load the exact GM-certified software and calibrations your vehicle needs to run correctly. Without it, the module will not function properly.
Is this part difficult to install?
Physically installing the module is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old unit. The location varies by vehicle (e.g., behind the RH strut tower on a Firebird, under the battery on a Silverado). The most important step is the security relearn procedure after installation.
What happens if I don’t perform the security relearn?
If the security relearn procedure is not completed, the vehicle’s anti-theft system will not recognize the new PCM. This will typically result in a ‘Security’ light on the dash and the engine will crank but not start.
Will this fix my Check Engine light?
If the Check Engine light is on due to an internal failure of your old PCM, then yes, this replacement module will resolve the issue. However, if the light is on because of a separate faulty sensor or component on the vehicle, that issue will still need to be addressed.
Is this a plug-and-play part?
It is as close as you can get. Because we program it to your VIN, it eliminates the need for expensive dealer programming. However, you must perform the security relearn procedure after installation for the vehicle to start.
