(2)  Directive 70/220/EEC, as amended by Directive 2002/ 80/EC, introduced specific requirements relating to the type-approval of bi-fuelled and mono-fuelled gas vehicles with respect to on-board diagnostic (OBD) systems. It also made provision for the type-approval, for a limited period of time, of gas-fuelled vehicle OBD systems containing minor deficiencies. It is necessary to comple- ment those provisions with additional technical measures covering the transmission of diagnostic signals in order to prevent a barrier to trade arising as a result of certain recently developed gas vehicle OBD technolo- gies that comply in all other respects with the require- ments of Directive 70/220/EEC. (3)  Directive 70/220/EEC, as amended by Directive 2002/ 80/EC, also introduced specific requirements relating to the EC-type-approval of replacement catalytic converters. Those requirements should be adjusted so that a replace- ment catalytic converter can be type-approved as a sepa- rate technical unit on the ground that it is of the same type as an original equipment catalytic converter or an original replacement catalytic converter for which type- approval has already been granted. (4)  Directive 70/220/EEC should therefore be amended accordingly. 1 () OJ L 42, 23.2.1970, p. 1. () OJ L 122, 16.5.2003, p. 36. () OJL 76, 6.4.1970, p. 1.
