low-level inducement system described in paragraph 5.3. shall be enabled, and subsequently activated according to the requirements of that section, if an error in the reagent consumption or an interruption in reagent dosing is not rectified within 10 engine operating hours after the activation of the driver warning system specified in paragraphs 8.4.1. and 8.4.2.
8.5.2. The severe inducement system described in paragraph 5.4. shall be enabled, and subsequently activated according to the requirements of that section, if an error in the reagent consumption or an interruption in reagent dosing is not rectified within 20 engine operating hours after the activation of the driver warning system in paragraphs 8.4.1. and 8.4.2.
8.5.3. 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.
9.  Monitoring failures that may be attributed to tampering
9.1. In addition to the level of reagent in the reagent tank, the reagent quality, and the reagent consumption, the following failures shall be monitored by the anti-tampering system because they may be attributed to tampering:
(a) Impeding of the EGR valve operation;
                  (b) Failures of the anti-tampering monitoring system, as described in paragraph 9.2.1.
9.2. Monitoring requirements
9.2.1. The anti-tampering monitoring system shall be monitored for electrical failures and for removal or deactivation of any sensor that prevents it from diagnosing any other failures mentioned in paragraphs 6. to 8. (component monitoring).
A non-exhaustive list of sensors that affect the diagnostic capability are those directly measuring NOx concentration, urea quality sensors, ambient sensors, and sensors used for monitoring reagent dosing activity, reagent level, or reagent consumption.
9.2.2. EGR valve counter
9.2.2.1. A specific counter shall be attributed to an impeded EGR valve. The EGR valve counter shall count the number of engine operating hours when any DTC associated with an impeded EGR valve is confirmed to be active.
9.2.2.2. Details of the EGR valve counter activation and deactivation criteria and mechanisms are described in Appendix 2 to this annex.
9.2.2.3. The EGR valve counter information shall be made available in a standardised manner in accordance with the provisions of Appendix 5 to this annex.
9.2.3. Monitoring system counters
9.2.3.1. A specific counter shall be attributed to each of the monitoring failures considered in point (b) of paragraph 9.1. The monitoring system counters shall count the number of engine operating hours when the DTC 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
