Proposal to amend UN R155 and UN R156 regarding approval authority requirements:

• Add a refusal ground to para. 5.1.3. of UN R155 where the Certificate of Compliance for the Cyber Security Management System has not been issued by the same approval authority granting type approval
• 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.
