WAMS2U (WAMS2U Remote Programming Service)

Services

WAMS's remote programming service. WAMS programs the customer's vehicle module remotely while the customer connects an MDI/MDI2 scan tool to their vehicle.

WAMS2U is the WAMS remote programming service. Instead of shipping a module to WAMS for programming, the customer keeps the module in their vehicle and WAMS performs the programming remotely via a scheduled session.

How WAMS2U works:

  • The customer schedules a session via the WAMS Contact page with order number reference
  • WAMS sends a software download link and a session token
  • At the scheduled time, the customer connects a genuine GM MDI1 or MDI2 scan tool (MDI2 required for Global B) to the vehicle’s diagnostic port, then to a Windows 10/11 laptop with a hardwired ethernet connection (Wi-Fi works but is less reliable; cellular hotspots do not work)
  • For Global A vehicles, the customer turns ignition to RUN. For Global B vehicles, ignition stays OFF.
  • WAMS performs the programming through the customer’s MDI and laptop while communicating via in-software chat
  • Programming standard hours are 9 AM – 5 PM Eastern; after-hours available for an additional fee

What WAMS2U is for:

  • Global B module marriages that cannot be completed without the module being physically in the vehicle (Techline Connect requirement)
  • Custom programming changes that don’t require the module to be removed
  • Feature unlocks and option enablement on installed modules
  • Situations where shipping a module isn’t practical (fleet vehicles, immobile vehicles)

Required equipment:

  • Genuine GM MDI1 (Global A only) or MDI2 (Global A or Global B)
  • Windows 10/11 PC with at least 8 GB memory and a working USB-A port
  • Hardwired ethernet connection or strong Wi-Fi
  • Vehicle battery fully charged, ideally on a charger/tender during the session

WAMS2U is available on services that explicitly offer it as a delivery method, and on certain services that are only available remotely.

Vehicle Applicability

All Global A vehicles (using MDI1 or MDI2) and Global B vehicles (MDI2 required). Specific service availability varies — see individual product pages.
