Programmed 1996 GM Engine Computer PCM 16211539 | Flashed to Your VIN

Is Your 1996 GM Vehicle Running Rough?

If you’re dealing with frustrating issues like intermittent stalling, a car that won’t start, poor fuel mileage, or a persistent Check Engine Light on your 1996 Buick, Chevy, Oldsmobile, or Pontiac, the problem often points directly to a failing Powertrain Control Module (PCM). As a technician with over 20 years of experience, I’ve seen these exact symptoms hundreds of times on vehicles like the Ciera, Regal, and Grand Prix. The original PCMs from this era are now reaching the end of their service life, leading to unpredictable and often hard-to-diagnose drivability problems.

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM PCM, service number 16211539 (interchangeable with 88963800 and 16231853), and professionally flash it with the latest GM-certified software calibrations. All we need is your vehicle’s 17-digit VIN to ensure a perfect match for your engine, transmission, and options.

Why a Programmed 1996 GM Engine Computer is the Smart Fix

In the mid-90s, vehicle electronics became more integrated. The PCM, or engine computer, controls everything from fuel injection and ignition timing to transmission shift points. When it fails, the symptoms can be all over the map. A customer’s ’96 Buick Regal came into the shop last month with a harsh 1-2 shift and random stalling at idle. After confirming the sensors and wiring were good, we traced it to an internal PCM fault. A pre-programmed module like this one had him back on the road in under an hour, with the car running better than it had in years. This module solves those issues by:

• ✔ Arriving Ready to Install: No need for expensive dealer programming or special scan tools.
• ✔ Being Flashed to Your VIN: We load the exact software your vehicle needs for optimal performance and emissions control.
• ✔ Containing the Latest GM Updates: Your module will have software improvements that address common factory drivability issues.
• ✔ Providing a Direct-Fit Solution: This unit is a direct replacement for a wide range of 1996 GM cars and vans.

Simple Plug-and-Play Installation

You don’t need to be a master mechanic to get your car running right again. Installing this module is a straightforward process:

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
2. Locate the PCM: On most of these vehicles, the PCM is located in the engine bay, often inside the air filter housing or mounted to the firewall.
3. Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and pull them straight out from the old module.
4. Swap the Module: Unbolt the old PCM, set the new one in its place, and secure it with the original hardware.
5. Reconnect and Power Up: Firmly plug the wiring harnesses into your new PCM until they click into place. Reconnect the negative battery terminal.
6. Perform Security Relearn: Your vehicle may require a simple key-cycle security relearn procedure. Turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds. Repeat this two more times. On the fourth try, the vehicle should start and run normally.
