SUMMARY

Establishes mandatory Cybersecurity Management System (CSMS) requirements for type approval of vehicles sold in contracting parties. OEMs must demonstrate cybersecurity processes throughout the vehicle lifecycle (development, production, post-production). Mandatory in EU since July 2022 (new types) and July 2024 (all new vehicles).

IMPACT / ANALYSIS

This is the foundation of global automotive cybersecurity regulation. Non-compliance blocks EU market access. Precondition for UN-R156 (software updates) and UN-R157 (ALKS) compliance.
