Is Your GM Truck or Van Running Rough?
If your late 90s or early 2000s Chevrolet, GMC, or Isuzu is suffering from erratic behavior like a persistent check engine light, poor fuel economy, harsh shifting, or even a frustrating no-start condition, the problem may lie with a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it begins to fail, it can cause a cascade of issues that are often difficult to diagnose, leading to wasted time and money on unnecessary sensor replacements.
The Direct Solution: A VIN-Programmed PCM
This isn’t just a replacement part; it’s a complete solution. We offer a Powertrain Control Module, compatible with part number 8162634940, that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates flawlessly with all other systems in your truck or van, just as the original did. We load the latest GM-authorized software updates, which can often resolve underlying drivability issues and improve overall performance and efficiency. Forget the hassle and expense of towing your vehicle to a dealership for programming. Our module arrives ready for installation.

Simple Ordering and Installation Process
1. Purchase: Complete your order for this module.
2. Provide VIN: Reply to our confirmation email or contact us with your 17-digit VIN. This is a mandatory step, as we cannot ship the module without programming it first.
3. Installation: Once you receive the module, disconnect the vehicle’s battery. Carefully remove the old PCM and install the new one. Reconnect the battery.
4. Security Relearn: In most cases, you will need to perform a simple security relearn procedure (often called a VATS or Passlock relearn). This procedure can be done without any special tools and typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This syncs the new PCM with your vehicle’s anti-theft system. Instructions are readily available online for your specific model.
This module is a direct fit for a wide range of GM vehicles. Please verify your original part number (16263494, 16265035, etc.) and check the extensive fitment list provided to ensure compatibility with your specific year, make, and model.
Frequently Asked Questions
What happens if I don’t provide my VIN?
We cannot ship your order without your vehicle’s VIN. The programming is essential for the module to function correctly in your vehicle. We will hold your order and contact you until the VIN is provided.
Is this a plug-and-play part?
Almost. It is plug-in, but you will need to perform a security relearn procedure after installation. This is a simple process that takes about 30 minutes and requires no special tools, just your ignition key.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty PCM, then yes, this module will resolve the issue. However, it’s crucial to ensure that the codes are not being caused by other failing components like sensors or wiring issues.
How do I find my original part number?
Your original part number is printed on a sticker on the PCM itself. You may need to remove the module from its bracket in the engine compartment to see the label clearly. Matching this number to our compatible list (16263494, 16265035, 8162634940) ensures you are ordering the correct hardware.
