Restore Peak Performance to Your 1996 GM Vehicle
Is your 1996 Chevrolet Lumina, Buick Regal, or Pontiac Grand Prix suffering from frustrating and unpredictable engine problems? Issues like a persistent Check Engine Light, rough idling, stalling, or a complete no-start condition often point to a failing Powertrain Control Module (PCM). This module is the electronic brain of your vehicle, meticulously managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, the entire vehicle’s performance and reliability are compromised.
This is a direct-replacement PCM, service number 16211539, which is fully compatible with original part numbers 88963800 and 16231853. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures that all factory settings are correct, all communications with other modules are seamless, and your vehicle operates exactly as the manufacturer intended. Simply provide your VIN after purchase, and we’ll handle the complex programming, shipping you a unit that’s ready for installation right out of the box.
Common Symptoms of a Failing PCM
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Vehicle fails to start or starts intermittently
- ✔ Rough or erratic engine idling
- ✔ Stalling or hesitation during acceleration
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ Failure to pass state emissions testing
- ✔ Unexplained error codes stored in the system
From the Diagnostic Bay
I once had a 1996 Buick Century come in with a classic no-start condition. The owner had already replaced the crank sensor and the ignition control module based on some forum advice, with no luck. When we hooked up our scanner, we could not establish communication with the PCM. Before condemning the module outright, we performed a ‘wiggle test’ on the main PCM harness and checked the power and ground pins. We found a corroded ground wire near the engine block that was causing an intermittent connection. After cleaning and securing the ground, the car fired right up. It’s a crucial reminder: always verify power, grounds, and wiring integrity before replacing a PCM. A few minutes with a multimeter can save you hundreds of dollars and a lot of frustration.
Why Choose Our 1996 Lumina PCM?
The 1996 model year was pivotal as it marked the mandatory implementation of OBD-II diagnostics across all U.S. vehicles. The PCM from this era is a sophisticated piece of hardware responsible for a complex network of sensors and actuators. A generic, non-programmed module from a salvage yard will not work correctly and can cause more problems than it solves. Our solution is tailored to your exact vehicle. We flash the unit with the latest GM-certified software updates, which can often resolve underlying drivability issues that were present even when the car was new. This isn’t just a replacement; it’s a restoration of your vehicle’s original logic and operational efficiency.
This 1996 Lumina PCM is a reliable and cost-effective solution to get your car back on the road. The installation is straightforward for a DIY mechanic or any professional technician. By providing a unit that is already programmed, we eliminate the need for expensive dealership tools or specialized programming services, saving you time and money.

Frequently Asked Questions
Do I need to do any programming after I receive this PCM?
No. We program the module with your vehicle’s specific VIN before it ships. This makes the unit ready for installation upon arrival. In some GM models, a security relearn procedure may be necessary, which can typically be done without special tools.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the part until we receive and validate your VIN.
Is this part compatible with my 3.1L, 3.4L, or 3.8L engine?
Yes, this PCM service number is used across multiple GM platforms with various engines from 1996, including the 3.1L (6-191), 3.4L (6-207), and 3.8L (6-231). Our VIN-specific programming ensures it has the correct software for your engine and transmission combination.
What if I install it and my problem doesn’t go away?
While this PCM will solve issues related to a faulty module, it’s important to ensure your vehicle has been properly diagnosed. Other components like sensors, wiring, or fuel system parts can cause similar symptoms. We recommend a thorough diagnosis before ordering.
What tools are needed for installation?
Installation is typically straightforward and requires basic hand tools, such as a socket set to remove the mounting bolts and disconnect the battery. The most important step is to disconnect the vehicle’s battery before starting the work to prevent electrical damage.
