It also specifies the test procedures to verify the requirements. DLC is an additional functionality that can be added to an MCS conforming to the general requirements specified in ISO/TS 23792‑1.
Means related to setting a destination and selecting a route to reach the destination are not in the scope of this document.
This document applies to the system installed in light vehicles.[2]
