Is Your 1998 Oldsmobile Bravada Running Rough?
If you’re dealing with a persistent check engine light, unexplained stalling, poor fuel mileage, or erratic transmission shifting, the problem often points directly to a failing Powertrain Control Module (PCM). As the brain of your Bravada’s engine and transmission, when the PCM starts to fail, it can cause a host of frustrating and hard-to-diagnose issues. In my 20+ years as a technician, I’ve seen these exact symptoms on countless GM trucks and SUVs from this era. The culprit is almost always a faulty engine computer.

Expert Pro Tip: Check Your Connections First
Before you replace your 1998 Bravada PCM, take 10 minutes to do this simple check. On these GM vehicles, corrosion on the main PCM connector pins or a weak ground connection can mimic a complete module failure. Disconnect the battery, unplug the PCM connectors, and inspect them for any green or white crusty buildup. Clean them with a dedicated contact cleaner and a small brush. Also, trace the main ground wire from the harness to the engine block or chassis and ensure it’s clean and tight. I’ve saved customers hundreds of dollars in my shop by finding a simple bad ground that was causing all the issues.
Easy Installation for Your 1998 Bravada PCM
You don’t need to be a master mechanic to swap this module. The process is straightforward and can be done with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On the 1998 Bravada, the PCM is typically located in the engine compartment, on the right-hand (passenger) side near the firewall or inner fender.
- Disconnect and Remove: Carefully unclip the wiring harness connectors. Then, unbolt the mounting brackets holding the old PCM in place and remove it.
- Install the New Module: Seat the new, programmed PCM into the mounting bracket and secure it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Reconnect Power: Reattach the negative battery terminal. The vehicle is now ready to start.
