Abstract

The invention concerns a method for aiding the remote diagnosis of a vehicle, implemented by a diagnostic aid device, comprising the following steps: - Downloading (31) a list of computers from a vehicle database, - Determining (32), for each computer of the list, a communication protocol for interacting with said computer, - Sending (33), for each computer, at least one diagnosis request according to the determined communication protocol, - Receiving (34) at least one response to the sent diagnosis request, - Updating (35) a diagnostic database from the received response.

Description

technical field [0001] The invention relates to a remote diagnostic assistance system for motor vehicles. Background technique [0002] The increase in electronics loaded onto a vehicle complicates maintenance of the vehicle. Faced with this complexity, vehicle manufacturers have developed always better performing self-diagnostic functions capable of pointing out abnormalities detected by their own on-board systems. [0003] Currently, maintenance operators arrange functions and indications (commonly referred to as trouble codes or DTCs (Diagnostic Trouble Codes)) assigned to different faults. In the garage, in order to locate the vehicle's fault exactly, the operator therefore uses functions of a very different nature: reading out information acquired on the vehicle, activating a test routine, restarting a learning program or downloading anomaly correction software. [0004] Before carrying out a diagnosis of a vehicle, it is necessary to evaluate the condition of the veh...
