Is Your GM Running Rough, Stalling, or Throwing Confusing Codes?
If you’re dealing with frustrating issues like a persistent check engine light, erratic engine performance, poor fuel economy, or even a no-start condition in your 1996 GM car or van, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a core problem that affects your vehicle’s reliability and your confidence on the road. You need a solution that works right out of the box, without expensive trips to the dealership for programming. This is that solution.
Common Symptoms of a Failing 1996 GM PCM & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other sensor failures. Before you continue replacing parts, see if these symptoms sound familiar:

A Mechanic’s Perspective: The 1996 OBDII Transition
As a technician, I remember 1996 well—it was the year On-Board Diagnostics II (OBDII) became mandatory on all new vehicles. The PCMs from this era, like the one in your Grand Prix or Lumina, were foundational to modern diagnostics. They are complex and must communicate perfectly with every sensor and module. That’s why simply installing a used, non-programmed module from a junkyard rarely works. It can cause transmission issues, security system lockouts, and a host of other problems. Our VIN programming service for the 1996 GM Programmed PCM 16211539 ensures all those digital handshakes happen correctly, just as the engineers intended.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), often called the Engine Control Module (ECM) or engine computer, is the electronic brain of your vehicle. It controls critical functions like fuel injection, ignition timing, transmission shifting, and emissions systems to ensure optimal performance and efficiency.
Do I need to do any programming myself?
No. This PCM arrives pre-programmed to the VIN you provide during checkout. The installation is a simple plug-and-play process. In some GM models of this era, a security relearn procedure may be necessary, which is a simple process that can be done without any special tools. We include instructions for this.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM or an issue the PCM controls, then yes, this part will resolve the problem. After installation, it’s always a good practice to clear any old codes with a standard OBDII scanner.
What happens after I place my order?
After you purchase, you will need to send us your vehicle’s VIN. We cannot ship the part until we receive this information. Once we have your VIN, we will program the module and ship it to you, typically within one business day.
Is this compatible with part number 16231853?
Yes. This module, service number 16211539, is a direct, compatible replacement for several service numbers, including 16231853 and 88963800. We program it to ensure it functions perfectly in your vehicle.
