Is Your GM Truck Running Rough or Refusing to Start?
There’s nothing more frustrating than a reliable truck, van, or SUV that suddenly won’t cooperate. If you’re dealing with a persistent check engine light, erratic shifting, a no-start condition, or poor fuel economy, the culprit is often a failing Powertrain Control Module (PCM). This component is the brain of your vehicle, and when it malfunctions, it can bring everything to a halt. Instead of facing a massive bill at the dealership, get your vehicle back on the road with this simple, effective, and affordable solution.
Common Symptoms of a Failing GM PCM & Your Solution
A faulty PCM can manifest in numerous ways, often confusing even experienced mechanics. If your vehicle is experiencing any of the following, our pre-programmed module is the definitive fix:
- No-Start or Stalling: The engine cranks but won’t start, or it stalls intermittently while driving.
- Harsh or Erratic Shifting: Your automatic transmission slams into gear, hesitates, or shifts at the wrong times.
- Check Engine Light with Error Codes: You may see codes like P0601 (Internal Control Module Memory Check Sum Error) or other communication-related faults.
- Poor Engine Performance: Noticeable loss of power, rough idling, and a significant drop in fuel mileage.
- Communication Failures: A scan tool is unable to communicate with the PCM.

Expert Insight: The Critical Role of VIN Programming
A common mistake we see is grabbing any old PCM from a salvage yard. While the part number might match, it won’t be programmed to your vehicle’s specific Vehicle Identification Number (VIN) and options. This inevitably leads to a no-start condition due to the factory anti-theft system (VATS/Passlock) and incorrect engine or transmission parameters. Our process eliminates this headache. We flash the module with the latest GM software calibrated specifically to your VIN, ensuring it communicates perfectly with your vehicle right out of the box. It’s the most reliable way to complete the repair without the dealership price tag.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module comes fully programmed to your vehicle’s VIN. In most cases, it is a plug-and-play installation. You may only need to perform a simple security relearn procedure, which takes about 30 minutes and requires only your key.
How do I provide my VIN?
After you place your order, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive the VIN.
What is the security relearn procedure?
For vehicles with VATS/Passlock anti-theft systems, you may need to perform a key relearn. This typically involves turning the key to the “ON” position for 10 minutes, off for 10 seconds, and repeating this cycle three times. This allows the new PCM to recognize your existing keys.
Is this a new part?
No, this is a high-quality, tested computer that was sourced from a salvaged vehicle. This allows us to provide a dependable and affordable solution for keeping these classic GM trucks and SUVs on the road.
Will this fit my vehicle if my part number is slightly different?
Yes, this unit is a direct replacement for multiple part numbers, including 09355699, 16266645, 9355699, 16250279, 16258815, and 09366810. As long as your vehicle is on the compatibility list, this Programmed 09355699 PCM will work perfectly.
