Unlock refers to transition of a doorlatch system into a state in which operation of the latch-release control is no longer inhibited, allowing the latch to disengage from the striker. Unlatching refers to transition into a state in which the latch and striker are no longer capable of withstanding separation forces, thereby allowing the door to move away from the vehicle body structure. Opening refers to the action by which a door is moved from its closed position to an open position through mechanical force or energizing an actuated device. Child Safety Lock System is a locking device which, when engaged, prevents operation of the interior door handle or other release device.

UN R155: Guidance for transformed vehicles
Reference Number: TFCS-37-05

Proposal to provide guidance on application of UN R155 to transformed vehicles. Transformations require new approval unless clear evidence shows original approval remains valid. Cyber-relevant modifications include addition of electrical/electronic systems, inappropriate interface connections, and wiring protection modifications. The approval authority determines whether transformation is cyber-relevant by assessing impact on original vehicle architecture, connection risks, cybersecurity management systems, and whether non-automotive equipment complies with relevant regulations. Manufacturers must provide documentary evidence including functional descriptions, connection details, software modifications, and compliance with original manufacturer instructions.

UN R155: Proposal for amendments from the workshop discussions
Reference Number: TFCS-37-04

Proposal to amend UN R155 by clarifying its scope to exclude certain equipment. The proposal amends paragraph 5.3.2. to require approval authorities to notify others of assessment methods and criteria. New paragraphs 8.2. and 8.3. establish that vehicle manufacturer installation of equipment with negligible intrinsic cyber security risk, or standard domestic, business or industrial equipment connected only for power, shall not require further assessment under paragraph 7, provided specified criteria are justified. Annex I is amended to include any equipment excluded from assessment pursuant to paragraphs 8.2. and 8.3.
