applicable;

               (b) The manufacturer shall submit this information to the Administrative  department within two months of the request;

               (c) The Administrative department shall transmit this information to the  Administrative departments of the Contracting Parties and the               Administrative department which granted the original type-approval               shall attach this information to Annex 1 of the vehicle type-approval               information.

               This requirement shall not invalidate any approval previously granted pursuant to Regulation No. 83 nor prevent extensions to such approvals under the terms of the Regulation under which they were originally granted.

              5.2.2. Information can only be requested for replacement or service components that are subject to UNECE type-approval, or for components that form part of a system that is subject to UNECE type-approval.

              5.2.3. The request for information must identify the exact specification of the vehicle model for which the information is required. It must confirm that the information is required for the development of replacement or retrofit parts or components or diagnostic tools or test equipment.
Annex 11 - Appendix 1
  Functional aspects of on-board diagnostic (OBD) systems
              1. Introduction
               This Appendix describes the procedure of the test according to paragraph 3. of Annex 11. The procedure describes a method for checking the function of the on-board diagnostic (OBD) system installed on the vehicle by failure simulation of relevant systems in the engine management or emission control system. It also sets procedures for determining the durability of OBD systems.
               The manufacturer shall make available the defective components and/or electrical devices which would be used to simulate failures. When measured over the Type I Test cycle, such defective components or devices shall not cause the vehicle emissions to exceed the limits of paragraph 3.3.2. by more than 20 per cent.
               When the vehicle is tested with the defective component or device fitted, the OBD system is approved if the MI is activated. The OBD system is also approved if the MI is activated below the OBD threshold limits.
              2. Description of test
              2.1. The testing of OBD systems consists of the following phases:
              2.1.1. Simulation of malfunction of a component of the engine management or emission control system,
              2.1.2. Preconditioning of the vehicle with a simulated malfunction over preconditioning specified in paragraph 6.2.1. or paragraph 6.2.2.
              2.1.3. Driving the vehicle with a simulated malfunction over the Type I Test cycle and measuring the emissions of the vehicle,
              2.1.4. Determining whether the OBD system reacts to the simulated malfunction and indicates malfunction in an appropriate manner to the vehicle driver.
              2.2. Alternatively, at the request of the manufacturer, malfunction of one or more components may be electronically simulated according to the requirements of paragraph 6. below.
              2.3. Manufacturers may request that monitoring take place outside
