Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with isO, also take part in the work. IsO collaborates closely with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 11898-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3 e Electrical and electronic equipment. 1O This first edition of IsO 11898-3 cancels and replaces IsO 11519-2:1994, which has been technically revised. The University ISO 11898 consists of the following parts, under the general title Road vehicles - Controller area network (CAN): Part1:Data link layerand physical signalling Part 2: High-speed medium access unit Library, Part 3: Low-speed, fault-tolerant, medium-dependent interface Part 4: Time triggered communication Licensedcopy:UniversityofManchester Part 5: High-speed medium access unit with low-power mode iv BS IS0 11898-3:2006 Introduction well as the high-speed physical layer. In the reviewed and restructured IsO 11898: isO 11898-1 describes the data link layer protocol as well as the medium access control; IsO 11898-2 specifies the high-speed medium access unit (MAU) as well as the mediu
