Restore Peak Performance to Your Oldsmobile Bravada
Is your 1998, 1999, or 2000 Oldsmobile Bravada suffering from baffling issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. A faulty PCM can disrupt communication between the engine and transmission, leading to a frustrating and unreliable driving experience. This replacement PCM, part number 16265035, is the definitive solution to restore your vehicle’s original performance and reliability.
We had a 1999 GMC Jimmy (which uses the same platform as the Bravada) come into the shop with a complaint of intermittent stalling and a check engine light for a random misfire. The owner had already replaced the spark plugs, wires, cap, and rotor, but the problem persisted. After hooking up our professional scan tool, we noticed the fuel trim data was completely erratic, jumping all over the place with no logical reason. This pointed away from a mechanical issue and towards the central controller. We swapped in a programmed PCM, and the truck ran perfectly. The original PCM had failing internal drivers, causing it to send incorrect signals. It’s a reminder that sometimes the root cause is the component controlling everything else.
Is Your Vehicle Exhibiting These Symptoms?
A failing PCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your PCM is the culprit. This replacement 1998-2000 Bravada PCM is designed to correct these exact problems:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Rough or unstable idling.
- ✔ Harsh, delayed, or erratic automatic transmission shifting.
- ✔ A sudden, unexplained drop in fuel mileage.
- ✔ The engine cranks but refuses to start.
- ✔ Intermittent stalling while driving or at a stop.
- ✔ Failure to pass state emissions testing.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission operation, including fuel injection, ignition timing, emissions systems, and shift points, to ensure optimal performance and efficiency.
Do I need to have this module programmed by a dealer?
No! That’s the primary benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, saving you a costly trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive your VIN.
Is installation difficult?
For a DIY mechanic with basic tools, installation is straightforward. It involves disconnecting the battery, locating and unplugging the old PCM (typically in the engine bay), installing the new one, and reconnecting the battery. You may need to perform a simple security relearn procedure, which can be found online or in a service manual.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty PCM, then yes, this part will resolve the issue. It’s crucial to properly diagnose the problem first, as the light can be triggered by other failing components like sensors or wiring.
