Is Your 1996 GM Vehicle Running Rough?
If you’re dealing with a frustrating no-start condition, a persistent check engine light, erratic shifting, or poor fuel economy in your 1996 Chevrolet Beretta, the Powertrain Control Module (PCM) is often the culprit. As a mechanic with over two decades of experience, I’ve seen how a failing engine computer can mimic a dozen other problems, leading to wasted time and money on incorrect repairs. This isn’t just a part; it’s the brain of your vehicle’s engine and transmission, and when it fails, your car’s reliability is gone.

Expert Pro Tip from the Shop Floor
Before installing your new PCM, take a moment to inspect the electrical harness connectors. Over the years, moisture and dirt can cause corrosion on the pins. I recommend using a quality electronics cleaner and a small nylon brush to gently scrub both the male and female ends of the connectors. A clean, solid connection is crucial for the PCM to communicate correctly with all the vehicle’s sensors. This simple five-minute check prevents a majority of post-installation communication errors I’ve seen in my bay.
Common Symptoms of a Failing 1996 Beretta PCM
A faulty PCM can manifest in various ways. If you’re experiencing any of the following, this module is the likely solution:

Plug-and-Play Installation: No Dealer Visit Required
Installing your VIN-programmed PCM is a straightforward process you can do in your own driveway. Follow these general steps to get your car back on the road:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most 1996 GM cars like the Beretta, the PCM is located in the engine bay, often near the firewall or inside the air filter housing.
- Disconnect Connectors: Carefully unclip the electrical wiring harnesses from the old module. There are typically two or three large connectors.
- Remove Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install New Module: Bolt the new, programmed PCM into place and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock in.
