Restore Your Truck’s Brain and Bring Back Peak Performance
Is your trusty 1997 GM truck or van feeling unpredictable? A failing Powertrain Control Module (PCM) is often the culprit behind a host of frustrating issues, from a rough idle to a sudden no-start condition. It’s the central computer, the brain of your vehicle, and when it falters, the entire system suffers. This direct-fit replacement module, compatible with part number 16229684, is the definitive solution to restore the smooth, reliable operation you depend on. We take the biggest headache out of the repair by programming the module to your specific Vehicle Identification Number (VIN) before it ships, ensuring it’s ready for a straightforward installation right out of the box.
Warning Signs Your PCM is Failing
Don’t let a faulty computer leave you stranded. If you’re experiencing any of these symptoms, it’s a strong indicator that your vehicle’s PCM needs attention. Replacing it can solve these problems and give you back the confidence of a dependable ride.
- ✔ Persistent Check Engine Light with codes like P0601, P0602, or P0605.
- ✔ Unexplained drops in fuel economy.

An Expert’s Note: The Diagnostic Wild Goose Chase
“I once had a customer with a ’97 Yukon who had spent nearly a thousand dollars replacing sensors, spark plugs, and even a fuel pump trying to fix an intermittent stalling issue. The truck ran fine for days, then would die at a stoplight without warning. After checking everything, we finally tested the PCM. The new, programmed module fixed it instantly. He called me a week later just to say how amazing it felt to drive without that constant worry in the back of his mind. Sometimes, the simplest solution is the right one.”
Guided Installation for a Confident Repair
You don’t need to be a master mechanic to complete this job. Our pre-programmed module makes this one of the most satisfying DIY repairs you can do. Follow these simple steps to get your vehicle back in top shape.
- Safety First: Always begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most 1997 GM trucks and vans, the PCM is located in the engine bay, typically on the driver’s side near the battery or firewall. It’s a silver metal box with several large wiring harness connectors.
- Disconnect and Remove: Carefully unplug the wiring harnesses. They have locking tabs that may need to be gently pried or squeezed. Once disconnected, unbolt the old module from its mounting bracket.
- Install the New 1997 Chevrolet 1500 PCM: Mount your new, pre-programmed module in the same location. Securely reconnect all the wiring harnesses, ensuring they click firmly into place.
- Power Up: Reconnect the negative battery terminal. The vehicle may need to go through a brief idle relearn procedure, but it’s now ready to start with its new, fully updated brain.

Frequently Asked Questions
Do I need to have this programmed by a dealer?
Absolutely not! The main benefit of our service is that we program the module to your vehicle’s specific VIN before shipping it to you. This saves you the time, hassle, and expense of a trip to the dealership. It arrives ready to install.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information, as the programming is unique to your vehicle.
Is any other setup required after installation?
In some cases, your vehicle may require a security relearn procedure, which is a simple process that can be done without any special tools. We include easy-to-follow instructions for this procedure if it’s necessary for your specific model.
What if my old part number is 8162296840?
This module is fully compatible. The part number 8162296840 is an alternative or service number for the primary part number 16229684. It will function identically in your vehicle.
What makes this a better choice than a junkyard part?
A used part from a junkyard will be programmed for the donor vehicle, not yours, and will not work correctly. Furthermore, our modules are inspected, tested, and loaded with the latest software updates from GM, ensuring optimal performance and longevity that you can’t get from a salvaged part.
