Is your 1996 Lumina, Grand Prix, or Regal acting up? If you’re dealing with a frustrating no-start condition, erratic engine behavior, or a check engine light that won’t go away, a failing Powertrain Control Module (PCM) is often the culprit.

Expert Insight: The Grounding Point Check
As a technician with over 20 years of experience, I’ve seen countless mid-90s GM vehicles with puzzling electrical issues. Before you replace any computer, do yourself a favor: check the main engine and body ground connections. On these cars, a corroded or loose ground strap can cause voltage fluctuations that mimic PCM failure and can even damage a new unit. A clean, tight ground is the foundation of a healthy electrical system. Installing this 1996 GM 16231853 PCM on a vehicle with solid grounds is the key to a lasting repair.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
Yes, you will likely need to perform a simple security relearn procedure, also known as a VATS relearn. This can typically be done without any special tools by turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the new PCM to synchronize with your vehicle’s anti-theft system. Instructions are readily available online for your specific model.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your 17-digit VIN to the order notes or send it to us in a message. We cannot program and ship your 1996 GM 16231853 PCM until we receive this information, as it is essential for a correct and functional part.
Is this the correct part for my car?
This unit is compatible with a wide range of 1996 GM models. The best way to confirm is to check the service number on your original computer’s sticker. If it matches 16231853, 16211539, or 88963800, this is the correct part for you. Please review the detailed fitment list on this page.
What causes a PCM to fail?
PCM failure is typically caused by age, heat cycles, and vibration over many years. Other causes can include electrical system damage from voltage spikes, short circuits in wiring or other components, and exposure to moisture.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within your original PCM, then yes, this part will resolve the issue and allow the codes to be cleared. However, if the light is on for a separate issue (like a bad oxygen sensor or EGR valve), that component will still need to be addressed.
