Is Your GM Truck or Van Running Rough?
There’s nothing more frustrating than a vehicle you can’t rely on. If your Chevrolet Express, Silverado, or GMC Sierra is suffering from a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s downtime that costs you time and money. This pre-programmed engine computer is the definitive solution to get your dependable workhorse back on the road, running strong.

- Engine Stalling or Misfiring for no apparent reason.
- Harsh or Failed Shifting as the PCM struggles to communicate with the transmission.
- Drastic Decrease in Fuel Mileage.
- Vehicle Won’t Start even with a good battery and starter.

Expert Insight: The Critical Role of VIN Programming
Many people are tempted to grab a used computer from a salvage yard, but this is almost always a mistake for these GM vehicles. Why? The PCM is tied directly to the vehicle’s anti-theft system (VATS/Passlock). A module from another vehicle will not have the correct security information and will prevent your engine from starting. Our VIN programming service not only loads the correct engine and transmission software but also synchronizes the module to your vehicle’s security, making the installation process as simple as swapping the part. This is the crucial step that ensures your vehicle starts and runs correctly right away.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the 16263494 PCM with the exact software and security calibration for your truck or van’s specific engine, transmission, and options. This step is essential for a true plug-and-play installation and ensures your vehicle will start and run correctly.
Is this part difficult to install?
For most of the compatible vehicles, the PCM is located in the engine bay and is held in by a few bolts and has several large electrical connectors. Installation is typically straightforward for someone with basic mechanical skills. The most important step is to disconnect the vehicle’s battery before starting the swap.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes include P0601-P0606), then this replacement module will solve the problem. However, if the light is on for another reason, such as a faulty sensor, that issue will need to be addressed separately.
What happens if I install it without programming?
An unprogrammed module will not work. Due to the GM anti-theft system, the vehicle will not start. Our mandatory VIN programming service handles this for you, so the part you receive is ready for installation.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis often requires a professional scan tool to check for communication errors with the module. Common signs include a lack of communication with the PCM, or specific internal fault codes. If your mechanic has condemned the PCM, this is the reliable replacement you need.
