Is Your 1996 GM Vehicle Running Rough?
If you’re dealing with frustrating engine problems in your 1996 Chevrolet Beretta, or another compatible GM model from that era, a failing Powertrain Control Module (PCM) is often the culprit. I’ve been diagnosing these vehicles for over two decades, and the symptoms are classic: the engine might crank but won’t start, it could stall unexpectedly at a stoplight, or the Check Engine Light is on with codes that just won’t clear. You’re not just buying a part; you’re buying a solution to get your trusted vehicle back on the road with confidence.
The Direct Solution: A VIN-Programmed PCM
This isn’t a generic, one-size-fits-all module from a salvage yard. This is a replacement PCM, service number 16211539, that we professionally program to your vehicle’s specific Vehicle Identification Number (VIN). This crucial step ensures that the computer has the correct software and calibrations for your engine, transmission, and options. We load the latest GM-released updates, which can often resolve performance and drivability issues that were present even on older software versions. Simply provide us with your VIN after purchase, and we handle the rest before it ships.
Expert Pro Tip: Check Your Connectors First!
Before you even think about installing your new PCM, take a minute to inspect the vehicle’s harness connectors. Over the years, the pins can get corroded (especially if the vehicle is in a wet climate) or even slightly bent. I’ve seen countless cases where a simple cleaning of the connector pins with a small brush and some electronics cleaner solved intermittent issues. A poor connection can mimic a failing PCM and can even damage your new part. A clean, secure connection is vital for a successful repair.
