Under this agenda item document ACV-03-02 was looked at.

The group considered that there should be a requirement for the numbering to be consistent with the definitions in 2.34.

Concerning point 5.1.3.6.2.3 the group decided that BPW should consider how the installation can be easily handled. This point will be come back to when Mr Manz from BPW is present in the meeting. Maybe we should say that the length and the capacitance has to be split to a maximum value. The Secretary is to send a message to Mr Manz to inform him that the meeting wanted to go to a specific length.

The group questioned as to whether the ISO 7638 : 2003 should be referred to instead of ISO 7638 : 1997.

A discussion was had on combinations consisting of both 12v and 24v vehicles. Conclusion was that a paragraph is needed to make it clear that it must be safe and possible to connect both. All brake related systems on the trailer powered through the brake electric/electronic interface should be capable of handling both voltages.

For point 5.1.3.6.2.6 the group considered that the input from the braking systems manufacturers is needed to know whether it is reasonable that all systems are supplied through the connector. How are trailers equipped today? Does 12v/24v tractor/trailer work? Can you move the vehicle if the EBS does not work? The Secretary is to ask the three braking systems manufacturers and Mr Manz to attend the next meeting of this working group.

The whole group is to review 5.1.3.6.3.2 and 5.1.3.6.3.3.

The group decided that it should point out that there are N1 vehicles capable of towing more than 3.5 tonnes. This is to be included in the open issues.

This document is to become ACV-03-02 Rev1, Results of discussions at the 3rd session.
