Is Your 1998 Bravada Running Rough, Stalling, or Refusing to Start?
If you’re dealing with frustrating engine problems in your Oldsmobile Bravada, a faulty Powertrain Control Module (PCM) is often the hidden culprit. Over time, the original electronics in these modules can fail, leading to a host of issues that can be difficult to diagnose. You might be experiencing erratic idling, poor fuel mileage, harsh transmission shifts, or a persistent check engine light that won’t go away. In my 20+ years as a technician, I’ve seen these exact symptoms hundreds of time on this GM platform.
A Technician’s Real-World Experience
A customer’s ’98 Bravada came in last week with a no-start condition that stumped two other shops. They had already replaced the fuel pump and ignition module. The engine would crank but never fire. After connecting my scan tool, I noticed the 5-volt reference signal to the throttle position sensor was dropping to zero intermittently. This is a classic sign of an internal PCM short. We installed one of our pre-programmed modules, and the vehicle fired up on the first try and ran perfectly. This simple swap saved the customer from hundreds more in diagnostic fees.

Plug-and-Play Installation: No Dealer Visit Required
You can perform this replacement yourself with basic hand tools. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the PCM: On the 1998 Bravada, the PCM is typically located in the engine compartment, on the passenger side fender well.
- Disconnect Connectors: Carefully unclip and remove the electrical wiring harnesses from the old module. Inspect the pins and connectors for any corrosion or damage.
- Remove Old Module: Unbolt the mounting brackets holding the old PCM in place and remove it from the vehicle.
- Install New Module: Mount your new, pre-programmed PCM and securely fasten the bolts.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click. Reconnect the negative battery terminal.
- Final Step: Start the engine. The vehicle will now run with the correct software for your specific VIN.
Expert Pro Tip: Crankshaft Variation Relearn (CASE)
After installation, your vehicle will run correctly. However, you may see a P1336 trouble code. This is normal and requires a “CASE Relearn” procedure to synchronize the new PCM with the crankshaft position sensor. Most professional scan tools can perform this function in a few minutes. While not always mandatory for the vehicle to run, completing this step ensures the most accurate misfire detection and optimal engine smoothness.
