Introduction
Remote diagnostic support is used for diagnosing vehicles at a distance prior to repair work, thereby
minimizing the time spent in workshops, reducing disturbances on the road network, reducing
inconvenience for the vehicle users and reducing cost for vehicle owners.
This document defines remote diagnostic support and the constraints that need to be respected. This
document may also serve as a reference for other standards that relate to remote diagnostic support.
This document will facilitate exchange of information for remote diagnostic support between the
different stakeholders (including vehicle manufacturers and independent operators) of the vehicle
repair industry.

using a standardized interface of the ExVe.
It concerns:
— the road vehicles with four or more wheels designed and constructed primarily for the carriage
of persons that are defined as Category 1 vehicles in the United Nations Special Resolution No.1 in
TRANS/WP.29/1045, as last amended on 19 June 2012, and
— the road vehicle with four or more wheels designed and constructed primarily for the carriage
of goods that are defined as Category 2 vehicles in the United Nations Special Resolution No.1 in
TRANS/WP.29/1045, as last amended on 19 June 2012,
where these road vehicles are still in accordance with the specifications of the vehicle manufacturer.
This document does not define the interfaces provided by the ExVe nor the internal implementation
inside the ExVe.
Processes like repair, prognostics, monitoring, configuration, re-programming and variant coding are
