Expert Insight: The Ghost in the Machine
As a technician, I’ve seen countless owners of these GMT360 platform trucks (Trailblazer, Envoy, Bravada) chase intermittent electrical gremlins for weeks. They replace sensors and check wiring, only for the stalling or no-start issue to return. Often, the root cause is the original PCM developing internal faults that don’t always set a clear trouble code. A failing module can cause perfectly good sensors to report bad data. Installing a quality, correctly programmed 2003-2004 Oldsmobile Bravada PCM isn’t just replacing a part; it’s restoring the vehicle’s central nervous system and eliminating the guesswork for a lasting repair.

Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive an email with instructions, or you can simply reply to your order confirmation email with your 17-digit VIN. We cannot program and ship the module without this information.
Is any additional programming required after installation?
No dealership programming is needed. However, you will need to perform a security relearn procedure, also known as a CASE relearn or Passlock relearn. This is a simple process that can be done in your driveway with just the key and takes about 30 minutes. We include clear instructions to guide you through it.
Will this fix my specific problem?
This module is the solution for issues directly caused by a faulty PCM, such as internal processor faults (P0601), no-communication errors, and certain injector or ignition coil driver failures. While it solves the most common electronic problems, you should always ensure your vehicle’s underlying mechanical and wiring systems are in good condition.
What if I order the wrong part?
Because we program the module to your specific VIN, compatibility is guaranteed. The VIN tells us everything we need to know to supply the correct hardware and software for your vehicle’s options, ensuring a perfect match every time.
What does the Lifetime Warranty cover?
Our warranty covers any failure of the module itself for as long as you own the vehicle. It is a testament to the quality of our components and programming process. The warranty is non-transferable and does not cover damage from external sources like vehicle wiring shorts or improper installation.
