Is your Silverado, Sierra, or Camaro running rough, shifting erratically, or failing to start? A faulty Powertrain Control Module (PCM) is often the culprit. As the central computer of your vehicle, the PCM manages everything from fuel injection and spark timing to transmission shift points. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This direct replacement Powertrain Control Module, part number 9354896, is the definitive solution to restore your vehicle’s performance, reliability, and drivability.
We take the guesswork out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit comes pre-programmed with the latest GM factory software updates specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after your purchase, and our technicians will flash the module to match your vehicle’s exact specifications. This ensures seamless integration and optimal performance right out of the box, eliminating the need for expensive dealership programming.
Common Symptoms of a Failing PCM
- ✔ Check Engine Light (CEL) is illuminated with various communication or sensor codes.
- ✔ Engine misfires, stalling, or rough idling.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start or intermittent starting condition.
- ✔ Poor fuel economy and noticeable loss of engine power.
- ✔ Inconsistent or non-functional electronic throttle control.
- ✔ Communication errors with diagnostic scan tools.
From the Diagnostic Bay
We had a 2000 Silverado 2500 towed in with a classic no-start condition. The owner had already replaced the battery, starter, and fuel pump with no luck. The engine would crank but never fire. Our initial scan showed no communication with the PCM. After checking all power and ground circuits to the module, we confirmed they were good. The final diagnosis was an internally failed PCM. We sourced a replacement GM PCM 9354896, programmed it to the truck’s VIN, performed the security relearn, and the truck fired up on the first try. It’s a perfect example of how a single component can mimic multiple other failures, making a correct diagnosis essential.

Frequently Asked Questions
Do I need to have this programmed by a dealer?
No. We program the module to the VIN you provide before shipping it. This means it arrives ready for installation, saving you a trip to the dealership and additional programming fees.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is installation difficult?
Installation is straightforward for someone with basic mechanical skills. The PCM is typically located in the engine bay (under the battery on most trucks). It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. After installing the new one, you may need to perform a security relearn procedure, which is a simple key-cycling process.
Will this fix my specific problem?
This module is a solution for a failed PCM. While the symptoms listed are very common for PCM failure, it’s always recommended to have a proper diagnosis performed by a qualified mechanic to rule out other potential issues like wiring or sensor problems.
What if I provide the wrong VIN?
The programming is specific to the VIN. An incorrect VIN will result in the module not working correctly with your vehicle. Please double-check your VIN for accuracy before sending it to us to ensure compatibility.
