accordance with this Regulation. Separate torque measurement during the inducement system demonstration is not required in this case. The speed limitation required for severe inducement shall be demonstrated in accordance with the requirements of paragraph 5. of this annex.
A.1.4.4. The manufacturer shall, in addition, demonstrate the operation of the inducement system under those failure conditions defined in paragraphs 7., 8. or 9. of this annex which have not been chosen for use in demonstration tests described in paragraphs A.1.4.1., A.1.4.2. and A.1.4.3. These additional demonstrations may be performed by presentation to the Type Approval Authority of a technical case using evidence such as algorithms, functional analyses, and the results of previous tests.
A.1.4.4.1. These additional demonstrations shall, in particular, demonstrate to the satisfaction of the Type Approval Authority the inclusion of the correct torque reduction mechanism in the engine ECU.
A.1.4.5. Demonstration test of the low level inducement system
A.1.4.5.1. This demonstration starts when the warning system, or when appropriate "continuous" warning system, has been activated as a result of the detection of a failure selected by the Type Approval Authority.
A.1.4.5.2. When the system is being checked for its reaction to the case of lack of reagent in the tank, the engine system shall be run until the reagent availability has reached a value of 2.5 per cent of the nominal full capacity of the tank or the value declared by the manufacturer in accordance with paragraph 6.3.1. of this annex at which the low-level inducement system is intended to operate.
A.1.4.5.2.1. The manufacturer may, with the agreement of the Type Approval Authority, simulate continuous running by extracting reagent from the tank, either whilst the engine is running or whilst it is stopped.
A.1.4.5.3. When the system is checked for its reaction in the case of a failure other than a lack of reagent in the tank, the engine system shall be run for the relevant number of operating hours indicated in Table 2 of Appendix 2 or, at the choice of the manufacturer, until the relevant counter has reached the value at which the low-level inducement system is activated.
A.1.4.5.4. The demonstration of the low level inducement system shall be deemed to be accomplished if, at the end of each demonstration test performed in accordance with paragraphs A.1.4.5.2. and A.1.4.5.3., the manufacturer has demonstrated to the Type Approval Authority that the engine ECU has activated the torque reduction mechanism.
A.1.4.6. Demonstration test of the severe inducement system
A.1.4.6.1. This demonstration shall start from a condition where the low-level inducement system has been previously activated, and may be performed as a continuation of the tests undertaken to demonstrate the low-level inducement system.
A.1.4.6.2. When the system is checked
