associated with a malfunction of the monitoring system is confirmed to be active. Grouping of several faults into a single counter is permitted.
9.2.3.2. Details of the criteria for activation and deactivation of the monitoring system counters and the associated mechanisms are described in Appendix 2 to this annex.
9.2.3.3. The monitoring system counter information shall be made available in a standardised manner in accordance with the provisions of Appendix 5 to this annex.
9.3. Activation of the driver warning system
The driver warning system described in paragraph 4. shall be activated in the case where any of the failures specified in paragraph 9.1. occurs, and shall indicate that an urgent repair is required. When the warning system includes a message display system, it shall display a message indicating either the reason for the warning (for example, "reagent dosing valve disconnected", or "critical emission failure").
9.4. Activation of the driver inducement system
9.4.1. The low-level inducement system described in paragraph 5.3. shall be enabled, and subsequently activated according to the requirements of that section, if a failure specified in paragraph 9.1. is not rectified within 36 engine operating hours after the activation of the driver warning system in paragraph 9.3.
9.4.2. The severe inducement system described in paragraph 5.4. shall be enabled, and subsequently activated according to the requirements of that section, if a failure specified in paragraph 9.1. is not rectified within 100 engine operating hours after the activation of the driver warning system in paragraph 9.3.
9.4.3. The number of hours prior to activation of the inducement systems shall be reduced in case of a repetitive occurrence of the malfunction in accordance with the mechanism described in Appendix 2 to this annex.

Annex 11 ‑ Appendix 1 Demonstration requirements
A.1.1.  General
