approval authority. The effective application of these strategies in protecting the odometer may be tested during type approval and/or regional market surveillance.
              5.1.6. It shall be possible to inspect the vehicle for roadworthiness test in order to determine its performance in relation to the data collected in accordance with paragraph 5.3.7. If this inspection requires a special procedure, this shall be detailed in the service manual (or equivalent media). This special procedure shall not require the use of special equipment other than that provided with the vehicle.
5.1.7. The use of defeat devices that reduce the effectiveness of emission control systems shall be prohibited. The prohibition shall not apply where:
                  (a) The need for the device is justified in terms of protecting the engine against damage or accident and for safe operation of the vehicle;

                  (b) The device does not function beyond the requirements of engine starting; or

                  (c) The conditions are substantially included in the test procedures for verifying evaporative emissions and average tailpipe emissions.

5.3. Description of tests
5.3.1. Reserved
5.3.2. Type 2 test (Carbon monoxide emission test at idling speed)
              5.3.2.1. This test is carried out on all vehicles powered by positive ignition engines, as follows:
              5.3.2.1.1. Vehicles that can be fuelled either with petrol or with LPG or NG/biomethane shall be tested in the Type 2 test on both fuels.
              5.3.2.1.2. Notwithstanding the requirement of paragraph 5.3.2.1.1., mono-fuel gas vehicles will be regarded for the Type 2 test as
