2,500 meters above sea level; and
(ii) At an ambient temperature of greater than or equal to 266 K (‑7 degrees Celsius); and
(iii) At an ambient temperature of lower than or equal to 308 K (35 degrees Celsius).
(b) Cumulative engine operation at or above 1,150 min-1 for greater than or equal to 300 seconds while under the conditions specified in the above subparagraph (a); as alternatives left to the manufacturer an engine operation at or above 15 per cent calculated load or a vehicle operation at or above 40 km/h may be used in lieu of the 1,150 min-1 criterion.
(c) Continuous vehicle operation at idle (e.g., accelerator pedal released by driver and either vehicle speed less than or equal to 1.6 km/h or engine speed less than or equal to 200 min-1 above normal warmed-up idle) for greater than or equal to 30 seconds while under the conditions specified in the above subparagraph (a).
5.5. Requirements for incrementing the ignition cycle counter
 The ignition cycle counter shall be incremented once and only once per driving cycle.
5.6. Incrementing disablement of the numerators, of the denominators and of the general denominator
5.6.1. Within 10 seconds of a malfunction being detected (i.e. a potential or a confirmed and active DTC is stored), which disables a monitor, the OBD system shall disable further incrementing of the corresponding numerator and denominator for each monitor that is disabled.
 When the malfunction is no longer detected (e.g. the potential DTC is erased through self-clearing or through a scan-tool command), incrementing of all corresponding numerators and denominators shall resume within 10 seconds.
5.6.2. Within 10 seconds of the start of operation of a Power Take-Off unit (PTO) that disables a monitor as permitted in paragraph 5.2.5. of Annex 9B, the OBD system shall disable further incrementing of the corresponding numerator and denominator for each monitor that is disabled.
 When the PTO operation ends, incrementing of all corresponding numerators and denominators shall resume within 10 seconds.
5.6.3. In the case of a malfunction (i.e. a potential or confirmed and active DTC has been stored) preventing determination of whether the criteria for the Denominatorm of a monitor m mentioned in paragraph 5.3. are satisfied[45], the OBD system shall disable further incrementing the Numeratorm and Denominatorm within 10 seconds.
 Incrementing the Numeratorm and Denominatorm shall resume within 10 seconds when the malfunction is no longer present (e.g., pending code erased through self-clearing or by a scan tool command).
5.6.4. In the case of a malfunction (i.e. a potential or confirmed and active DTC has been stored) preventing determination of whether the criteria for the General denominator mentioned in paragraph 5.4. are satisfied, the OBD system shall disable
