Is Your 1997 GM Vehicle Running Rough? It Could Be The PCM.
If you’re experiencing frustrating issues like erratic engine behavior, poor fuel mileage, harsh transmission shifts, or a persistent Check Engine Light in your 1997 Buick Park Avenue, Pontiac Bonneville, or other compatible GM model, the root cause is often a failing Powertrain Control Module (PCM). As the central computer for your vehicle, the PCM governs everything from fuel injection and ignition timing to transmission shift points and emissions control. When it begins to fail, it can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs.
This replacement Powertrain Control Module, part number 16227797, is the definitive solution to restore your vehicle’s original performance and reliability. We take the guesswork out of the equation by programming the module specifically for your car using the VIN you provide. This ensures that all factory settings and the latest GM software updates are loaded, making installation as straightforward as possible.
Symptoms of a Failing 1997 Park Avenue PCM
A faulty PCM can manifest in various ways. If you’re noticing any of the following symptoms, it’s a strong indicator that your engine computer may need replacement:
- ✔ Unexplained Check Engine Light illumination
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel economy
- ✔ Failure to pass an emissions test
- ✔ Intermittent no-start condition where the engine cranks but won’t fire
- ✔ Communication errors with diagnostic scan tools
The Importance of VIN Programming
You cannot simply take a PCM from another vehicle and install it in yours. The module is programmed with specific data for the engine, transmission, gear ratios, tire size, and emissions equipment of the original vehicle. Our service eliminates this complexity. By providing your Vehicle Identification Number (VIN) during checkout, you receive a module that is a true plug-and-play component for your exact vehicle configuration. This critical step ensures all systems communicate correctly and your vehicle operates exactly as the manufacturer intended.
Installation and Relearn Procedure
Once you receive your pre-programmed 1997 Park Avenue PCM, the physical installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then reversing the process to install the new one. However, after installation, most 1997 GM vehicles will require a security relearn procedure (often called Passlock or VATS) and a Crankshaft Variation Relearn (CASE). The security relearn allows the module to communicate with your vehicle’s anti-theft system, and the CASE relearn synchronizes the new PCM with the crankshaft position sensor for accurate misfire detection. These procedures can often be performed by a qualified mechanic or with a capable bi-directional scan tool.

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready for installation with the latest GM software for your specific car.
What is a CASE relearn and will I need to perform one?
A CASE (Crankshaft Angle Sensor Error) relearn synchronizes the PCM with the crankshaft position sensor. This is required on most GM vehicles after PCM replacement to ensure accurate engine misfire detection and prevent a false Check Engine Light. This procedure must be performed with a compatible professional scan tool after the module is installed.
Is this part difficult to install?
The physical replacement of the module is typically simple, requiring basic hand tools to disconnect the battery and swap the unit. The more technical part is performing the security and CASE relearn procedures after installation, which may require a trip to a mechanic if you do not own a high-level scan tool.
What happens if I install this without doing the security relearn?
If the security relearn is not performed, the vehicle’s anti-theft system will not recognize the new PCM, and the engine will not start. The ‘Security’ light on your dashboard will likely be illuminated or flashing.
This module looks the same as mine, but the part number is different. Will it work?
This module is a direct replacement for part numbers 16227797 and 19109047. As long as your vehicle is on the compatibility list and your original part number is one of these two, this module will function correctly once programmed to your VIN.
