Restore Peak Performance to Your Vehicle
Is your 1996 Chevrolet Beretta, Cavalier, or another compatible GM vehicle suffering from frustrating and unpredictable engine problems? Symptoms like a persistent Check Engine Light, rough idling, stalling, or poor fuel economy often point to a failing Powertrain Control Module (PCM), the central computer of your vehicle. This replacement PCM, part number 16215830, is the definitive solution to restore your engine’s reliability and efficiency. It arrives at your door pre-programmed to your specific vehicle’s VIN, ensuring a seamless, plug-and-play installation without the need for an expensive trip to the dealership.
We once had a 1996 S10 pickup in the shop that was a real head-scratcher. The owner had already replaced the throttle position sensor and the idle air control valve trying to fix a stubborn stalling issue at traffic lights. The codes were intermittent and pointed to a few different circuits. Instead of continuing to replace parts, we connected a lab scope to the 5-volt reference line coming from the PCM. We saw the voltage dropping out randomly, which was causing the sensors to give false readings. The root cause wasn’t the sensors at all; it was the PCM’s internal voltage regulator failing. A new, properly programmed computer had the truck running perfectly in under an hour. It’s a powerful reminder that when multiple, unrelated sensors start acting up, it’s often the central computer that’s the real culprit.
Common Symptoms of a Failing PCM
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your PCM could be the cause:
- ✔ Persistent Check Engine Light: The light stays on, and you may have error codes that are inconsistent or point to multiple sensor failures.
- ✔ No-Start or Hard-Starting: The engine cranks but refuses to start, or takes an unusually long time to fire up, due to incorrect fuel or spark commands.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and an overall sluggish feeling.
- ✔ Reduced Fuel Economy: The engine runs inefficiently, consuming more fuel than usual because the air-fuel mixture is not being managed correctly.
- ✔ Erratic Shifting or Transmission Issues: On automatic transmission models, the PCM also controls shift points. A failing module can cause harsh or delayed shifts.
- ✔ Failed Emissions Test: Incorrect engine management leads to higher-than-normal emissions, resulting in a failed smog check.
Why Our VIN-Programmed Module is the Superior Choice
This isn’t just a generic, off-the-shelf part. It’s a comprehensive solution tailored to your exact vehicle. When you provide us with your VIN, we flash the module with the latest, most stable GM-approved software for your car’s specific configuration. This critical step ensures:
- Perfect Compatibility: The PCM will correctly manage your specific engine, transmission, and emissions equipment.
- Proper Anti-Theft Function: For vehicles equipped with systems like GM’s VATS (Vehicle Anti-Theft System), VIN programming is essential for the vehicle to start and run.
- Plug-and-Play Installation: No need for additional programming or expensive scan tools. Simply disconnect the old module and install the new one.

Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the PCM. This is critical because it ensures the computer knows your car’s engine size, transmission type, and security settings. Without it, your vehicle may not start or run correctly.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. It typically involves disconnecting the battery, locating the old PCM (often in the engine bay or under the dashboard), unplugging the electrical connectors, swapping the unit, and reconnecting everything. No special tools are usually required.
What information do you need from me after I order?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). You can usually find this on your dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, it’s important to properly diagnose the problem first. If the light is on due to a bad sensor or wiring issue, this part will not fix that underlying problem.
Do I need to send my old computer back?
This listing does not require you to return your old part (core). You can keep it or dispose of it as you see fit.
