Is your 1997 Grand Prix, Monte Carlo, or another trusted GM vehicle suddenly running rough, stalling, or refusing to start? The frustration of an unreliable car can disrupt your entire day.

Expert Insight: The Anti-Theft System Connection
A common mistake when replacing a PCM on these 90s GM vehicles is using a standard, non-programmed unit from a salvage yard. These will not work because of the factory Vehicle Anti-Theft System (VATS/PassKey). The original PCM is electronically ‘married’ to your key’s security chip. Our service of programming the module to your VIN before shipping is essential. It allows the new PCM to correctly communicate with your car’s security system, enabling it to start and run. While a simple 30-minute security relearn procedure is sometimes needed after install (see our FAQ), our programming does the critical heavy lifting for you.
Don’t let a faulty computer keep your car off the road. This programmed 1997 Grand Prix PCM 16227797 is the most effective and straightforward way to solve complex electronic issues and make your car dependable again.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives at your door fully programmed to your vehicle’s VIN and ready for installation. In some cases, a simple 30-minute security relearn procedure may be necessary, which involves turning the key on and off and requires no special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email. We cannot ship the module until we have your VIN to ensure correct programming.
What if my original part number is 19109047?
This module is a direct, compatible replacement for several part numbers, including 19109047. As long as your vehicle’s make, model, and year are on our compatibility list, we will program it to function perfectly for your specific application.
Is this a difficult part to install?
For most individuals with basic hand tools, this is a straightforward DIY job. The process typically involves disconnecting the car battery, locating the original PCM (often near the air filter box), unplugging the electrical harnesses, swapping the modules, and reconnecting everything.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal failure of your original PCM (e.g., code P0601), then this replacement will resolve the issue. However, if the light is on for another reason, such as a faulty sensor, that separate issue will still need to be addressed.
What is the security relearn procedure?
If your vehicle’s ‘Security’ or ‘Theft’ light is on after installation, you’ll need to perform a simple relearn. Turn the key to the ‘ON’ position (without starting) for 10 minutes, then ‘OFF’ for 10 seconds. Repeat this cycle three times. On the third cycle, the car should start and run normally.
