Restore Peak Performance to Your GM Vehicle
Is your 1998 Oldsmobile Bravada, Chevy S10, GMC Jimmy, or another compatible GM truck or van suffering from frustrating issues like a persistent check engine light, poor fuel economy, rough idling, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission performance. Don’t let a faulty computer keep you off the road. This genuine, used GM PCM, part number 9355699, is the reliable and cost-effective solution you need.
The Importance of a Properly Functioning 1998 Bravada PCM
The PCM is the brain of your vehicle’s operation. It constantly analyzes data from sensors throughout the engine and drivetrain to make real-time adjustments to fuel delivery, ignition timing, transmission shift points, and emissions controls. When it begins to fail, the entire system’s harmony is disrupted, leading to a cascade of performance problems. Replacing a faulty unit is critical not only for restoring drivability but also for protecting other expensive components from potential damage caused by incorrect engine parameters.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Vehicle refuses to start or is very difficult to start
- ✔ Rough or erratic engine idle
- ✔ Stalling or hesitation during acceleration
- ✔ Noticeable decrease in fuel efficiency
- ✔ Harsh or unpredictable automatic transmission shifting
- ✔ Failure to pass emissions testing

Where can I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
