Is your GM truck, van, or SUV suffering from erratic performance, a persistent Check Engine Light, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the culprit, acting as the brain of your vehicle and causing widespread issues when it malfunctions. Don’t let a faulty computer keep your reliable workhorse off the road. This is the direct, professionally prepared solution to restore your vehicle’s performance and get you back to work with confidence.
Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely cause. This module is the definitive fix for issues such as:
- Persistent Check Engine Light: Especially with communication-related Diagnostic Trouble Codes (DTCs) like P0600, P0601, P0602, P0605, or P0606.
- Engine Performance Problems: Rough idling, stalling, misfires, poor acceleration, and a noticeable decrease in fuel economy.
- Transmission Issues: Harsh or delayed shifting, or the transmission getting stuck in one gear (limp mode).
- No-Start or Intermittent Starting: The engine cranks but won’t start, or only starts sometimes, due to the PCM failing to control the fuel or spark systems correctly.
Our solution is a high-quality, dependable Powertrain Control Module. The key is our expert programming service. We flash this programmed GM PCM 16263494 with the latest official GM software updates, precisely matched to your vehicle’s unique Vehicle Identification Number (VIN).

Expert Insight: The Critical Role of Correct Programming
As a veteran technician, I’ve seen countless vehicle issues caused by improperly matched electronics. A PCM isn’t just a simple part you can swap from another truck. It contains specific data for the engine size, transmission type, gear ratios, and even tire size. Using a non-programmed or incorrectly programmed module can lead to immediate running problems or long-term damage. Our process of using your VIN to install the latest GM calibration ensures this computer integrates perfectly, just as it did from the factory, giving you a lasting and reliable repair.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is any additional programming needed after installation?
In most cases, no. This module is sent to you ready for installation. However, some vehicles may require a security relearn procedure (often called CASE relearn or Passlock relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available online for your specific model.
How can I be sure this part will fit my vehicle?
Please check the extensive fitment list on this page carefully. The most important step is to match one of the compatible OEM part numbers (like 16263494) to the number on your existing module. Providing your VIN for programming is the final step that guarantees compatibility for this programmed GM PCM 16263494.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Engine Control Unit) is a general term. ECM (Engine Control Module) typically controls only the engine. A PCM (Powertrain Control Module) is more integrated and controls both the engine and the transmission, which is common in the vehicles this part fits.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal failure of your original PCM, then yes, this part is designed to resolve that. It is crucial to properly diagnose the vehicle first to ensure the fault lies with the module and not a sensor, wiring, or other component.
