TCA is currently developing a functional and technical specification for On-Board Mass (OBM) systems.

The Specification is being developed in consultation with the Telematics Industry Group (TIG) and OBM system suppliers.

The Specification will:

  • Provide appropriate levels of data security
  • Define electronic control unit and mass sensor unit functionality and capability
  • Address requirements for detection of turntable position where applicable

The Specification is scheduled to be finalised by August 2016, followed by the commencement of type-approvals for OBM systems.
