Proposal to amend para. 5.1.3. of UN R155 to add a refusal ground where the Certificate of Compliance for the Cyber Security Management System has not been issued by the same approval authority granting type approval, and insert new para. 5.4. into UN R156 to provide that approval authorities shall not grant any type approval if the Certificate of Compliance for the Software Update Management System has not been issued by the same approval authority granting type approval. The proposal, based on TFCS-37-02, ensures that Certificates of Compliance and type-approvals for UN R155 and UN R156 are issued by the same approval authority to enable holistic assessment and clarify reporting obligations.
