Expert Insight: The Critical Role of VIN Programming
Many people are tempted to grab a used computer from a salvage yard, but this is a classic mistake for these GM vehicles. Without proper VIN programming, the module won’t communicate correctly with the Body Control Module (BCM) and other vehicle systems. This often leads to a no-start condition due to the anti-theft system (VATS/Passlock) or severe transmission shifting problems. Our service eliminates that risk entirely. By providing us with your VIN, you’re getting a component that is electronically identical to the original, ensuring all systems work together as the factory intended.
This module is a direct replacement for multiple part numbers, including 16263494, 16265035, and 8162634940. Ordering a programmed 16263494 PCM from us is the most reliable way to solve complex electronic issues and ensure your vehicle remains a dependable workhorse. Simply provide your VIN after purchase, and we’ll handle the rest.

What information do you need from me?
After you place your order, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific truck or van.
Do I need to have my keys reprogrammed after installation?
In most cases for these specific vehicles, no. Our programming process correctly sets up the module to communicate with your vehicle’s existing systems. However, some GM models may require a simple security relearn procedure that you can do yourself in about 15-30 minutes without any special tools. We can provide instructions if needed.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment component that has been verified for full functionality. We then program it with fresh, vehicle-specific software, making it a reliable and lasting repair solution.
Where is the PCM located on my vehicle?
The location varies slightly. On most Savana and Express vans, it’s in the engine compartment on the driver’s side, near the rear. On many pickups and SUVs like the Tahoe or Silverado, it’s under the hood on the driver’s side, often near the battery or fender well. On S10/Blazer models, it’s typically on the passenger side fender well.
Will this fix my vehicle’s specific problem?
This programmed 16263494 PCM is the solution for a wide range of electronic, performance, and communication issues caused by a faulty computer. While proper diagnosis is always recommended, the symptoms listed above are classic indicators of PCM failure for which this part is the correct fix.
