Restore Peak Performance to Your GM Vehicle
Is your Firebird, Camaro, or Silverado suffering from frustrating issues like a persistent Check Engine Light, rough idling, poor fuel economy, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. A faulty PCM can disrupt everything from fuel delivery and spark timing to transmission shifting, making your vehicle unreliable. This replacement PCM, part number 9354896, is the definitive solution to get your vehicle running smoothly and efficiently again.
The biggest challenge with replacing a PCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Before this module ships, our technicians will program it with the latest GM-certified software, specifically matched to your vehicle’s VIN. This means it arrives at your door ready for a straightforward installation, saving you hundreds of dollars and significant downtime. Simply provide your VIN at checkout, and we handle the complex part for you.
Case Study: A Tricky Diagnosis
A customer brought in a 2000 Silverado 2500 with a complaint that stumped a couple of other shops: intermittent stalling at stoplights, but with no consistent trouble codes. We could feel a slight hesitation and saw the fuel trims were erratic. After verifying fuel pressure and checking for vacuum leaks, we suspected the PCM. In my experience, heat-soak can cause these older PCMs to develop internal faults that don’t always throw a P0601 code right away. We swapped in a pre-programmed unit like this one, and the truck ran perfectly. The VIN-specific programming ensured all the factory settings for that heavy-duty truck were correct, providing a fast and permanent fix.
Is Your Vehicle Showing These Symptoms?
- ✔ Unexplained Check Engine Light (CEL) illumination
- ✔ Diagnostic Trouble Codes (DTCs) such as P0601, P0602, or P0606
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Noticeable decrease in fuel mileage
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass state emissions testing
- ✔ Complete no-start condition where the engine cranks but won’t fire
A Straightforward Guide to Installation
Installing your new 1999-2002 Firebird PCM is a job most DIYers can handle with basic tools. This module is designed for a direct fit, making the process simple. Follow these steps to get back on the road:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On Firebirds and Camaros, it’s typically behind the passenger-side strut tower in the engine bay. On trucks like the Silverado or Sierra, it’s often under the hood on the driver’s side, below or near the battery.
- Disconnect Connectors: Carefully unplug the electrical wiring harnesses from the old PCM. There are usually two or three large connectors with locking tabs.
- Remove the Old Module: Unbolt the PCM from its mounting bracket. Keep the hardware, as you may need to reuse it.
- Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and securely reconnect all wiring harnesses. Ensure they click into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn: Your vehicle may require a simple security relearn procedure to recognize the new PCM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for the specific procedure for your model.

Frequently Asked Questions About This PCM
Does this PCM really come programmed?
Yes. We flash the module with the latest software from GM using the Vehicle Identification Number (VIN) you provide. This ensures it’s a true plug-and-play solution, with no need for a trip to the dealer for programming.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship the module until we receive this information to perform the necessary programming.
Is this a difficult part to install myself?
For most DIY mechanics with basic hand tools, this is a very manageable job. The module is typically easy to access in the engine bay, and the process involves unplugging the old unit and plugging in the new one. See our installation guide above for more details.
Will this fix my car’s specific problem?
This PCM is a direct solution for issues caused by a faulty module, such as internal processor errors (P0601), erratic engine behavior, and communication failures. If your vehicle has been properly diagnosed with a bad PCM, this part will resolve those symptoms.
What is a “security relearn” and will I need to do it?
A security relearn syncs the new PCM with your vehicle’s anti-theft system. Most GM vehicles of this era require it. It’s a simple, tool-free procedure that usually involves leaving the key in the ‘ON’ position for about 10-15 minutes. Your vehicle will not start until this is completed.
