Is Your Bravada or GM Truck Driving You Crazy?
If you’re dealing with a 1998-2000 Oldsmobile Bravada, or one of the many GM trucks and vans it shares a platform with, you might be experiencing some frustrating issues. Maybe it’s a check engine light that won’t go away, no matter what parts you throw at it. Perhaps it’s an intermittent no-start condition that leaves you stranded, or the engine stalls for no apparent reason. These are classic symptoms of a failing Powertrain Control Module (PCM), the central computer of your vehicle.
Over my 20+ years in the shop, I’ve seen hundreds of these specific GM PCMs fail. They live in a harsh engine bay environment, and after two decades of heat cycles and vibrations, the delicate internal circuits and solder joints simply break down. This can lead to a cascade of confusing problems that can mislead even experienced mechanics.
From the Shop Floor: A Real-World Scenario
“A customer’s ’99 Bravada came in last week with these exact symptoms. It had a check engine light with codes for the O2 sensor, the MAP sensor, and a transmission solenoid. The owner had already replaced all those parts, but the light came right back. The truck would also randomly stall at red lights. After verifying the wiring and sensors were good, we connected our diagnostic tool and found the PCM was intermittently losing communication. This confirmed our suspicion: the computer itself was the root cause. A faulty PCM was sending bad signals, making good parts seem faulty. This is a story I’ve seen play out time and time again with these vehicles.”
The Direct-Fit, Programmed Solution
Replacing the PCM used to mean a costly trip to the dealership for the part, installation, and programming. This module eliminates that hassle. We provide a high-quality replacement Powertrain Control Module that is the definitive solution for restoring your vehicle’s performance and reliability.
Why This is the Best Choice for Your Vehicle:
- โ VIN Programmed: This isn’t a generic, one-size-fits-all part. We flash the module with your vehicle’s specific VIN and install the latest, most stable software updates from General Motors. This ensures perfect compatibility and can even resolve drivability issues that were present from the factory.
- โ Plug & Play Installation: Because the module arrives programmed for your exact vehicle, installation is straightforward. In most cases, after installation, you will only need to perform a simple security relearn procedure (often called a Passlock or VATS relearn), which you can do yourself without special tools.
- โ Solves Annoying Electrical Gremlins: A new PCM is often the final fix for a host of problems that seem unrelated.
- โ Restores Original Performance: Get back the smooth shifting, consistent idle, and proper fuel economy you’ve been missing.
Guaranteed Compatibility
This module is a direct replacement for units with the following part numbers: 16263494, 16265035, 8162634940, and 21811787.
