features which avoid excess evaporative emissions in the case of a missing fuel filler cap;
              5.1.4.3. Any other provision which has the same effect. Examples may include, but are not limited to, a tethered filler cap, a chained filler cap or one utilising the same locking key for the filler cap as for the vehicle's ignition. In this case, the key shall be removable from the filler cap only in the locked condition.
5.1.5.  Provisions for electronic system security
              5.1.5.1. Any vehicle with an emission control computer shall include features to deter modification, except as authorised by the manufacturer. The manufacturer shall authorise modifications if these modifications are necessary for the diagnosis, servicing, inspection, retrofitting or repair of the vehicle. Any reprogrammable computer codes or operating parameters shall be resistant to tampering and afford a level of protection at least as good as the provisions in ISO DIS 15031-7, dated October 1998 (SAE J2186 dated October 1996), provided that the security exchange is conducted using the protocols and diagnostic connector as prescribed in paragraph 6.5. of Annex II, Appendix 1. Any removable calibration memory chips shall be potted, encased in a sealed container or protected by electronic algorithms and shall not be changeable without the use of specialised tools and procedures.
              5.1.5.2. Computer-coded engine operating parameters shall not be changeable without the use of specialised tools and procedures (e. g. soldered or potted computer components or sealed (or soldered) computer enclosures).
              5.1.5.3. In the case of mechanical fuel-injection pumps fitted to compression-ignition engines, manufacturers shall take adequate steps to protect the maximum fuel delivery setting from tampering while a vehicle is in service.
              5.1.5.4. Manufacturers may apply to the Approval Authority for an exemption to one of these requirements for those vehicles which are unlikely to require protection. The criteria that the Approval Authority will evaluate in considering an exemption will include, but are not limited to, the current availability of performance chips, the high-performance capability of the vehicle and the projected sales volume of the vehicle.
              5.1.5.5. Manufacturers using programmable computer code systems (e.g. Electrical Erasable Programmable Read-Only Memory, EEPROM) shall deter unauthorised reprogramming. Manufacturers shall include enhanced tamper protection strategies and write protect features requiring electronic access to an off-site computer maintained by the manufacturer. Methods giving an adequate level of tamper protection will be approved by the authority.
              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. of this Regulation. 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
