The GM VIP Platform (also known as Global B) is a highly advanced vehicle architecture designed around security, scalability, and continuous software updates. Because of how this platform operates, there are a few important considerations to ensure consistent, factory-correct performance when upgrading or replacing modules.
Throughout this page, “WAMS modules” means any module WAMS programmed to your VIN — whether the module was supplied by WAMS or custom-programmed by WAMS on hardware you provided. These considerations apply only to those modules. Every other module on your vehicle can be diagnosed, serviced, reprogrammed, and updated by a dealership as normal.
For your dealer or installer: Any module WAMS supplied or custom-programmed for this vehicle is already programmed to this VIN. Work on those modules only if WAMS provided written instructions, and follow them exactly — otherwise leave them as delivered. Do not run a vehicle-wide software update on this vehicle — it will attempt to reflash every module, including WAMS modules. Update individual modules only. All other modules on the vehicle can be serviced as normal.

Over-the-Air (OTA) and Dealer-Initiated Updates
Many Global B vehicles receive OTA updates directly from GM, which can change module software without advance notice. To protect the VIN-specific calibration, decline OTA updates on your WAMS modules after installation — an OTA can overwrite programming or create compatibility issues.The same applies at the dealership. A vehicle-wide software update must not be performed on this vehicle, because that process automatically scans and attempts to reflash every module on the bus — including your WAMS modules — regardless of whether an update was needed. Updates must be selected and run one module at a time. Any individual module other than a WAMS module can be updated normally this way.

Final Setup Procedures
Certain Global B upgrades (such as instrument clusters) require a final in-vehicle setup after installation using GM Techline Connect and a GM MDI2 tool. Any GM dealer can perform these steps, as can many mobile locksmiths and independent shops. Because Global B key programming runs through the same GM system, any locksmith who can program a key to your vehicle can complete these procedures. The customer is responsible for locating a shop or service in their area to have these steps completed.When a final setup is required, WAMS provides detailed written instructions with your order. Review them before any work begins.

Providing Instructions to Your Installer
If a dealership or independent technician is assisting with installation, make sure they have the instruction sheet included with your order. This keeps the process correct and prevents unintended reflashing or reprogramming of your WAMS modules. -
Work on WAMS Modules Only as Our Instructions Direct
WAMS modules arrive already programmed to your VIN. A dealer or technician should touch a WAMS module only when WAMS has provided written instructions — and those instructions must be followed to the letter. If no instructions cover a step, don’t perform it. In particular, never reflash or reprogram a WAMS module through SPS2 unless our instructions direct it; doing so overwrites the VIN-specific calibration and can disable the upgrade. -
Returning to Factory Configuration
If you choose to reinstall your original factory components, those modules may need a similar final setup to reinitialize them to the vehicle. This procedure is performed by a dealer or qualified shop and is not covered by the instructions supplied with your order however we can assist with information to facilitate that
If anything is unclear, or if a WAMS module has been reflashed, updated, or worked on outside our written instructions, stop and contact WAMS before proceeding. Reaching out first is almost always faster and less costly than correcting it afterward.
This process is designed to ensure reliable operation, proper integration, and long-term system stability on the Global B platform.
