Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to the VIN you provide. It is designed to be a plug-and-play installation. In some cases, a simple security relearn procedure may be required, which takes only a few minutes and does not require any special tools.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. You can typically reply to your order confirmation email or follow a link to a secure submission form.
Is this the correct part for my car?
This computer is a direct replacement for part numbers 16217058 and 16218070. It fits a wide range of 1997 GM vehicles, including the Pontiac Grand Prix, Buick LeSabre, Chevy Monte Carlo, and Oldsmobile Silhouette, among others listed in the fitment chart. Please verify your part number to ensure compatibility.
What is the security relearn procedure?
For vehicles equipped with a GM Passlock or VATS security system, you may need to perform a simple key-cycle procedure after installation. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the new PCM to recognize your vehicle’s key and security system.
How can I be sure my old PCM is the problem?
While the symptoms listed are strong indicators of PCM failure, we always recommend a thorough diagnosis by a qualified mechanic. Common checks include verifying power and ground signals to the computer and checking for communication with a professional scan tool. This ensures you are ordering the correct part for your issue.
