Is Your Bravada Running Rough? Get Back to a Smooth, Confident Drive.
There’s nothing more frustrating than an engine that won’t cooperate. If you’re dealing with a persistent check engine light, sputtering, poor fuel economy, or harsh shifting in your Oldsmobile Bravada, a failing Powertrain Control Module is often the culprit. This isn’t just an annoyance; it’s a core issue that affects your vehicle’s reliability and your peace of mind on the road. This replacement PCM is the definitive solution, engineered to restore your vehicle’s brain to perfect working order.
We take the guesswork and hassle out of the repair. Unlike a generic module from a parts store, this unit arrives at your door specifically programmed for your vehicle. Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates. This ensures it communicates flawlessly with your engine, transmission, and all related systems, just as it did the day it left the factory. Regain that worry-free drive and the confidence that your truck will start and run smoothly every single time.
Warning Signs and How to Overcome Them
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your engine’s computer needs attention:
- ✔ Persistent Check Engine Light (CEL) with codes like P0601, P0605, or other communication errors.
- ✔ Unexplained stalling or difficulty starting the engine.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough idling or engine misfires.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle enters ‘limp mode’ with reduced power.
Replacing the module with our pre-programmed unit directly addresses these issues, restoring communication between critical systems and bringing back the dependable performance you rely on.
Expert Mechanic’s Tip
Before installing your new PCM, take a moment to inspect your vehicle’s battery terminals and main ground connections. A weak or corroded connection can cause voltage drops that mimic PCM failure. Ensuring these are clean and tight is a simple step that guarantees your new module has the stable power it needs to operate perfectly for years to come.

- Disconnect the Harnesses: Carefully unplug the electrical connectors from the old PCM. There may be locking tabs that need to be gently released.
- Remove the Old Unit: Unbolt the old module from its mounting bracket and remove it from the vehicle.
- Install the New PCM: Mount your new, pre-programmed PCM onto the bracket and securely re-fasten the bolts.
- Reconnect and Secure: Plug the wiring harnesses firmly into the new module until they click into place. Reconnect your vehicle’s negative battery terminal.

Frequently Asked Questions
Do I need to do any programming myself?
No, you don’t! The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This means it’s ready for installation right out of the box, saving you a costly trip to the dealership.
What is the security relearn procedure?
In many GM vehicles, the security system (Passlock/VATS) needs to sync with the new PCM. This is usually a simple process involving turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. Your vehicle’s manual may have specific instructions.
Will this fix my check engine light?
If the check engine light is on due to a faulty PCM (e.g., internal processor error codes), then yes, this replacement will resolve the issue. It’s always best to have the codes scanned first to confirm the diagnosis.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information for programming.
Is this a new or used part?
This is a professionally serviced original equipment part that has been thoroughly tested, cleaned, and prepared to provide reliable, long-lasting performance. All internal software is updated to the latest available from the manufacturer during the programming process.
