1998 Bonneville PCM Powertrain Control Module 9366314 Programmed to VIN

Is Your 1998 Bonneville or GM Vehicle Driving You Crazy?

If you’re dealing with a car that seems to have a mind of its own, you’re not alone. In my 20+ years as a technician, I’ve seen countless late-90s GM vehicles, like the Bonneville, Grand Prix, and LeSabre, come into the shop with baffling symptoms. The owner has often replaced multiple sensors, spark plugs, and wires, yet the core problem remains: a persistent Check Engine Light, unpredictable stalling, harsh or delayed transmission shifts, or even a complete no-start condition. More often than not, the root cause isn’t a faulty sensor—it’s the brain of the operation, the Powertrain Control Module (PCM), that has failed.

The Silent Failure: Why PCMs Go Bad

The PCM is the central computer managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. It lives in a harsh environment, constantly exposed to heat and vibration. Over two decades, the delicate internal electronic components, like capacitors and solder joints, begin to break down. This degradation doesn’t always cause a complete, obvious failure. Instead, it creates intermittent, ghost-like problems that are a nightmare to diagnose. A failing PCM can send out incorrect signals, making you think you have a bad mass airflow sensor or a faulty transmission solenoid when the real issue lies with the computer itself.

The Guaranteed Solution: A VIN-Programmed PCM

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the equation. When you order, you provide us with your vehicle’s 17-digit VIN. We then professionally program this module with the latest, most stable software updates directly from GM, ensuring it is perfectly matched to your vehicle’s specific configuration and options. This eliminates the need for a costly trip to the dealership for programming.
