connection for the 'Antilock System' meeting Appendix 1 clauses 1.3.1 to 1.3.3.

       1.1.1    Where the vehicle also provides an electrical 'Control Signal' via an electric 'Control Line', the electrical connection shall conform to ISO 11992-1 and 11992-2:2003 and be a point-to-point type using the seven pin connector according to ISO 7638-1 or 7638-2:1997. The data contacts of the ISO 7368 connector shall be used to transfer information exclusively for braking (including the 'Antilock System') and running gear (steering, tyres and suspension) functions as specified in ISO 11992-2:2003.

        The braking functions have priority and shall be maintained in the normal and failed modes. The transmission of running gear information shall not delay braking functions. The power supply, provided by the ISO 7638 connector, shall be used exclusively for braking and running gear functions and that required for the transfer of trailer related information not transmitted via the electric 'Control Line'.

        However, in all cases, whenever power supplied by the ISO 7638:2003 connector is used for the functions defined in this paragraph above, the braking system shall have priority and be protected from an overload external to the braking system. This protection shall be a function of the braking system. The power supply for all other functions shall use other measures. Whenever power supplied by the ISO 7638:1997 connector is used for the functions defined above, the braking system shall have priority and be protected from an overload external to the braking system. This protection shall be a function of the braking system.

APPENDIX 2
       Special Provisions for vehicles incorporating an Electronic Stability Control System where required by Clause 4.1.1.1.

         The following is a modified form of Annex 9 of UNECE Regulation No. 13-H– UNIFORM PROVISIONS CONCERNING THE APPROVAL OF PASSENGER CARS WITH REGARD TO BRAKING, incorporating supplement 7 and corrigendum to supplement 7 of the 00 series of amendments.

0.                                          DEFINITIONS
0.1.                                    "Ackerman steer angle" means the angle whose tangent is the wheelbase divided by the radius of the turn at a very low speed.
0.2.                                    "Electronic Stability Control System" or "ESC System" means a system that has all of the following attributes:
0.3.                                    That improves vehicle directional stability by at least having the ability to automatically control individually the braking torques of the left and right wheels on each axle [1]/ to induce a correcting yaw moment  based on the evaluation of actual vehicle behaviour in comparison with a determination of vehicle behaviour demanded by the driver;
0.4.                                    That is computer controlled with the computer using a closed-loop algorithm to limit vehicle oversteer and to limit vehicle understeer based on the evaluation of actual vehicle behaviour in comparison with a determination of vehicle behaviour demanded by the driver;
0.5.                                    That
