Restore Peak Performance to Your GM SUV
Is your Oldsmobile Bravada, Trailblazer, or Envoy plagued by baffling electrical problems, a persistent check engine light, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the culprit, acting as a faulty brain for your vehicle’s most critical systems. This isn’t just an inconvenience; it’s a matter of reliability. You’ve found the definitive, hassle-free solution to get your trusted SUV back on the road with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing PCM is the likely cause. This module is the permanent fix for:
- Erratic engine performance, stalling, or rough idling
- Poor fuel economy
- Failure to communicate with OBD-II scan tools
- Illuminated Check Engine Light with internal processor codes (e.g., P0601, P0606)
- Harsh or incorrect automatic transmission shifting
- Complete no-start or intermittent starting issues

Expert Insight: Why VIN Programming is Non-Negotiable
On these GM GMT360 platform vehicles (like the Bravada, Trailblazer, and Envoy), the PCM is tied directly to the vehicle’s anti-theft system (Passlock II). Simply swapping a computer from another vehicle will result in a no-start condition every time. Our VIN-flashing service pre-loads your vehicle’s unique security information and operational parameters onto the module. This ensures that when you install it, the other modules in your vehicle recognize it as the correct component, allowing for a seamless and successful repair. This is the only way to correctly replace the PCM outside of a dealership.
Don’t let a faulty computer keep your reliable SUV sidelined. This programmed 2003-2004 Bravada PCM is the most efficient and effective way to solve complex running issues and restore the dependable operation you need for work, family, and daily life. You are getting more than just a part; you are getting a complete, ready-to-install solution backed by expert support.
Frequently Asked Questions
Do I need to do anything after installation?
Yes, you will need to perform a simple security relearn procedure, which can be done without any special tools and typically takes about 30 minutes. We provide clear, easy-to-follow instructions to guide you through this process.
How do I provide my VIN?
After you complete your purchase, you can add your 17-digit Vehicle Identification Number (VIN) to the ‘notes’ section of your order. If you forget, we will contact you via email to retrieve it before we program and ship your module.
Will this fit vehicles other than the Oldsmobile Bravada?
Absolutely. This PCM is compatible with a wide range of 2003-2006 GM SUVs built on the same platform, including the Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Isuzu Ascender, and Saab 9-7X, primarily with the 4.2L 6-cylinder engine. Please verify the part number to ensure an exact match.
Will this fix my specific problem or Check Engine Light code?
This module is a guaranteed fix for internal PCM failure, often indicated by codes like P0601 through P0606. While it can resolve many other drivability issues, it’s essential to ensure your vehicle’s problem has been properly diagnosed. This part will not fix issues caused by other faulty sensors or mechanical components.
Is this a new or used computer?
This is a genuine, original equipment component that has been meticulously inspected, tested, and prepared by our technicians to meet or exceed factory specifications. This ensures perfect fitment and function without the high cost of a new-from-dealer part.
