Is Your 1998-2000 Bravada Driving You Crazy?
If you’re dealing with a Check Engine Light that won’t go away, rough idling, stalling, or a frustrating no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, when the PCM starts to fail, it can create a cascade of confusing and intermittent issues that are a nightmare to diagnose. I’ve seen these exact symptoms hundreds of times on the GM 4.3L platform in my 20+ years in the shop.
Common Symptoms of a Failing Bravada PCM
Your vehicle’s PCM is constantly working, managing everything from fuel mixture and spark timing to transmission shift points. After two decades of heat, vibration, and countless electrical cycles, internal components can and do fail. You might be experiencing:
- โ Check Engine Light (CEL) with communication-related or random sensor codes.
- โ Engine stalling or shutting off while driving.
- โ Harsh or erratic automatic transmission shifting.
- โ A complete no-start condition where the engine cranks but won’t fire.
- โ Noticeable decrease in fuel economy and overall performance.
- โ Failure to pass an emissions test.
Expert Pro Tip: The “No-Bus” Problem
A classic failure I see on these GM PCMs is an internal communication breakdown. Your scan tool will say it can’t communicate with the module, or you’ll get a “No Bus” message. This is often caused by failed capacitors or a cracked solder joint on the main processor. Before condemning wiring, always suspect the PCM itself, especially on a vehicle of this age. Swapping the module is often the fastest and most accurate diagnostic step.
