                  The test requirement is satisfied if the system delivers an alert by the time the pressure drop has reached 100 kPa.
               
            2.2.   Test procedures for detecting a failure of the run-flat warning system
      
      2.2.1.   With the vehicle in the normal use condition, simulate a run-flat warning system failure. This may be simulated by, for example, disconnecting connectors for wiring related to the power supply from the power source or wiring related to the input/output to/from the warning system control.
      2.2.2.   With a simulated fault introduced, drive the vehicle normally between 40 and 100 km/h.
      2.2.3.   The test is completed when either:
      
                  (a)
               
               
                  the run flat malfunction signal as described in paragraph 5.1.6.4 has activated; or
               
            
                  (b)
               
               
                  a period of 5 minutes has elapsed, when determined in accordance with paragraph 2.3, from the time the test speed has been reached. If the warning does not activate the test has failed.
               
            The vehicle shall be brought to a halt and the ignition switched off.
      2.2.4.   If the warning signal as required in paragraph 2.2.3 above has activated, wait 5 minutes before turning the ignition on; the signal must reactivate and remain active as long as the ignition switch is in the ‘on’ (‘run’) position.
      2.3.   Calculation of time duration
      
      The time to be taken for determination of the requirements of paragraphs 2.1.1.5 and 2.2.3 shall be the total elapsed time while the vehicle is driven in the test speed range 40 km/h to 100 km/h.
      The time shall be calculated over a continuous drive but it is not necessary that the vehicle maintains throughout the test a speed within the test speed range. Where the vehicle speed falls outside the test speed range, any time accumulated during such events shall not be considered as part of the total test time duration.
      The type approval authority shall satisfy itself that the run flat warning system records the time within the test speed range on a cumulative basis and does not restart the time calculation if the vehicle falls outside the test speed range.

Inflate the vehicle’s tyres to the vehicle manufacturer’s recommended cold inflation pressure (Prec), in accordance with the vehicle manufacturer’s recommendation for the speed and load conditions, and tyre positions. All pressure measurements shall be carried out using the same test equipment.
      2.2.   With the vehicle stationary and the ignition locking system in the ‘Lock’ or ‘Off’ position, activate the ignition locking system to the ‘On’ or ‘Run’ position. The tyre pressure monitoring system shall perform a check of lamp function for the low tyre pressure tell-tale as specified in paragraph 5.3.5.2 of this Regulation. [This last requirement does not apply to tell-tales shown in a common space.]
      2.3.   If applicable, set or reset the tyre pressure monitoring system in accordance with the vehicle manufacturer’s recommendations.
      2.4.   Learning phase
      
      2.4.1.   Drive the vehicle for a minimum of 20 minutes within the speed range in paragraph 1.4.2 to this Annex, and with an average speed of 80 km/h (+/– 10 km/h). It is allowed to be outside the speed range for a maximum cumulative time of 2 minutes during the learning phase.
      2.4.2   At the discretion of the technical service, where the driving test is undertaken on a track (circle/oval) with only turns in a single direction, then the driving test in paragraph 2.4.1 above should be equally split (+/– 2 minutes) in both directions.
      2.4.3   Within the 5 minutes of completing the learning phase, measure the warm pressure of the tyre(s) to be deflated. The warm pressure shall be taken as the value Pwarm. This value will be used for subsequent operations.
      2.5.   Deflation phase
      
      2.5.1.   Procedure for the puncture test to verify the requirements of paragraph 5.3.2 to this Regulation
      
      Deflate one of the vehicle’s tyres within 5 minutes of measuring the warm pressure as described in paragraph 2.4.3 above, until it is at Pwarm – 20 per cent, or it is at a minimum pressure of 150 kPa, whichever is higher, namely Ptest. Following a stabilisation period of between 2 and 5 minutes the pressure Ptest shall be rechecked and adjusted if necessary.
      2.5.2.   Procedure for the diffusion test to verify the requirements of paragraph 5.3.3 to this Regulation
      
      Deflate all four tyres within 5 minutes of measuring the warm pressure as described in paragraph 2.4.3 above, until the deflated tyres are at Pwarm – 20 per cent plus a further deflation of 7 kPa, namely Ptest. Following a stabilisation period of between 2 and 5 minutes the pressure Ptest shall be rechecked and adjusted if necessary.
      2.6.   Low tyre pressure detection phase
      
      2.6.1.   Procedure for the puncture test to verify the requirements of paragraph 5.3.2 to this Regulation
      
      
                  2.6.1.1.
               
               
                  Drive the vehicle along any portion of the test course (not necessarily continuously). The sum of the total cumulative drive time shall be the lesser of 10 minutes or the time at which the low tyre pressure tell-tale illuminates.
               
            2.6.2.   Procedure for the diffusion test to verify the requirements of paragraph 5.3.3 to this Regulation
      
      
                  2.6.2.1
               
               
                  Drive the vehicle along any portion of the test course. After not less than 20 minutes and not more than 40 minutes bring the vehicle to a complete standstill with the engine switched off and the ignition key removed for not less than 1 minute or more than 3 minutes. Resume the test. The sum of the total cumulative drive time shall be the lesser of 60 minutes of cumulative driving under the conditions set out in paragraph 1.4.2 above or the time at which the low tyre pressure tell-tale illuminates.
               
            2.6.3.   If the low tyre pressure signal did not illuminate, discontinue the test.
      2.7.   If the low tyre pressure tell-tale illuminated during the procedure in paragraph 2.6 above, deactivate the ignition locking system to the ‘Off’ or ‘Lock’ position. After a 5 minutes period, reactivate the vehicle's ignition locking system to the ‘On’ (‘Run’) position. The tell-tale must illuminate and remain illuminated as long as the ignition locking system is in the ‘On’ (‘Run’) position.
      2.8.   Inflate all of the vehicle's tyres to the vehicle manufacturer’s recommended cold inflation pressure. Reset the system in accordance with the instructions of the vehicle manufacturer. Determine whether the tell-tale has extinguished. If necessary, drive the vehicle until the tell-tale has been extinguished. If the tell-tale does not extinguish, discontinue the test.
      2.9.   Repetition of the deflation phase
      
      The test may be repeated, at the same or different loads, using the relevant test procedures in paragraphs 2.1 to 2.8 above, with the relevant tyre(s) on the vehicle under-inflated, in accordance with the provisions of paragraph 5.3.2 or 5.3.3 to this Regulation, whichever is relevant.
      3.   TPMS MALFUNCTION DETECTION
      3.1.   Simulate a TPMS malfunction, for example, by disconnecting the power source to any TPMS component, disconnecting any electrical connection between TPMS components, or installing a tyre or wheel on the vehicle that is incompatible with the TPMS. When simulating a TPMS malfunction, the electrical connections for the tell-tale lamps shall not be disconnected.
      3.2.   Drive the vehicle for up to 10 minutes of cumulative time (not necessarily continuously) along any portion of the test course.
      3.3.   The sum of the total cumulative drive time under paragraph 3.2 shall be the lesser of 10 minutes or the time at which the TPMS malfunction tell-tale illuminates.
      3.4.   If the TPMS malfunction indicator did not illuminate in accordance with paragraph 5.3.4 to this Regulation, as required, discontinue the test.
      3.5.   If the TPMS malfunction indicator is illuminated or illuminates during the procedure in paragraphs 3.1 to 3.3 above, deactivate the ignition locking system to the ‘Off’ or ‘Lock’ position. After 5 minutes, reactivate the vehicle's ignition locking system to the ‘On’ (‘Run’) position. The TPMS malfunction indicator shall again signal a malfunction and remain illuminated as long as the ignition locking system is in the ‘On’ (‘Run’) position.
      3.6.   Restore the TPMS to normal operation. If necessary, drive the vehicle until the warning signal has extinguished. If the warning lamp has not extinguished, discontinue the test.
      3.7.   The test may be repeated using the test procedures in paragraphs 3.1 to 3.6 above, with each such test limited to simulation of a single malfunction.
