Restore Peak Performance to Your 1997 GM Vehicle
Is your 1997 Chevrolet Lumina, Pontiac Grand Prix, or Buick Regal suffering from frustrating and unpredictable issues? A faulty Powertrain Control Module (PCM), also known as an Electronic Control Module (ECM), is often the hidden culprit behind a wide range of engine and transmission problems. This vital component is the central brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it fails, the symptoms can be confusing and lead to costly, incorrect repairs. This replacement module, part number 16227797, is the definitive solution to restore your vehicle’s original performance and reliability.
Common Symptoms of a Failing Powertrain Control Module
If you’re experiencing any of the following issues, a failing PCM could be the cause. Don’t continue to replace sensors and other components without addressing the core problem. A failing computer can send false signals, making other perfectly good parts appear faulty.
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns with various codes.
- ✔ Rough or erratic idling and stalling.
- ✔ A noticeable decrease in fuel economy.
- ✔ Harsh or delayed transmission shifting.
- ✔ Engine hesitation, misfires, or a general lack of power.
- ✔ The vehicle fails to start intermittently or cranks but won’t turn over.
- ✔ Communication errors with diagnostic scan tools.
From the Diagnostic Bay
We had a 1997 Pontiac Bonneville with the supercharged 3.8L come into the shop. The owner had spent hundreds of dollars replacing the mass airflow sensor and multiple oxygen sensors trying to chase down a lean condition code and poor performance. The car would run fine for a day, then fall flat on its face. After confirming the sensors were good, we hooked up our scope to the PCM connectors. We found the injector driver circuit for cylinder 3 was intermittently dropping out. The PCM itself was failing internally, causing the misfire and lean code. We installed a VIN-programmed module just like this one, and the car ran perfectly. It’s a classic case of the symptoms pointing one way, but the root cause being the computer.
The Importance of a Properly Programmed 1997 Lumina Control Module
Simply installing a used module from another vehicle will not work. Each PCM is programmed with software specific to a vehicle’s Vehicle Identification Number (VIN). This programming accounts for the engine size, transmission type, emissions equipment, and other factory options. Our service eliminates the guesswork and the need for an expensive trip to the dealership. We take your vehicle’s VIN and flash this module with the latest, most stable software updates directly from GM. This ensures that your new 1997 Lumina Control Module not only works perfectly but also benefits from any drivability or performance improvements released by the manufacturer since your car was built.
This module is a direct-fit replacement for original part numbers 16227797 and 19109047. It is meticulously inspected to ensure full functionality and is ready for installation upon arrival. The process is straightforward: provide your VIN during or after checkout, and we handle all the complex programming. When you receive the part, it’s a true plug-and-play solution.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN, and the module will arrive ready to install. This saves you time and the high cost of dealership programming.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is the installation process difficult?
Installation is typically straightforward for someone with basic mechanical skills. It involves disconnecting the battery, locating the old module, unplugging the electrical connectors, unbolting it, and then reversing the process with the new module. In some cases, a simple security relearn procedure (like turning the key on for 10-15 minutes) may be required.
What happens if I install it without it being programmed to my VIN?
An unprogrammed or incorrectly programmed module will not work. It can cause a no-start condition, incorrect engine and transmission operation, and will likely illuminate the check engine light. Our VIN programming service is essential for proper vehicle function.
Will this fix my check engine light?
If the check engine light and associated diagnostic codes are being caused by a faulty PCM, then this part will be the solution. However, it’s always recommended to have the codes professionally diagnosed to ensure the PCM is the root cause and not another sensor or component.
