Is Your 1998 Oldsmobile Bravada Running Rough?
If you’re dealing with a frustrating no-start condition, intermittent stalling, a persistent Check Engine Light, or just poor engine performance in your Bravada, the Powertrain Control Module (PCM) is a very common culprit. Over two decades of heat cycles and vibrations under the hood can take their toll on the sensitive electronics inside. In my 20+ years as a technician, I’ve seen these exact symptoms on countless GM trucks and SUVs from this era. The good news is, you’ve found the right solution.
The Smart, Simple Fix: A VIN-Programmed 1998 Bravada PCM
This isn’t just a used part pulled from a yard. This is a reliable, OEM Powertrain Control Module that we professionally program to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the computer has the correct software and calibrations for your Bravada’s engine, transmission, and options. It’s a plug-and-play solution designed to get you back on the road without the high cost and hassle of a dealership visit.
Expert Pro Tip: Check Your Connections First
Before you condemn your old PCM, take a moment to inspect the electrical connectors. On these GM vehicles, the large multi-pin connectors for the PCM can accumulate green or white corrosion, especially in humid climates. Disconnect the battery, unplug the PCM, and use a small brush and electrical contact cleaner to thoroughly clean both the harness-side plugs and the pins on the module. A poor connection can mimic a complete PCM failure. I’ve saved customers hundreds of dollars in my shop with this simple 10-minute check.

- Locate the PCM: On the 1998 Bravada, the PCM is typically found in the engine compartment, often on the driver’s or passenger’s side fender well.
- Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and unplug them from the old module.
- Remove the Old Unit: Unbolt the PCM from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed module in place, securely reconnect the electrical harnesses, and then reconnect your battery terminal.
