  • Communication with the VCI 1 and thus one or more electronic control units in the vehicle 10 can be established via the vehicle test device 3c with the help of the central diagnostic server device 2, so that, for example, the new steering angle sensor can be registered or learned in the corresponding electronic control device of the vehicle 10 ( Step 53d).
  • a result protocol is then again created (step 53e).
  • the vehicle 10 is brought to a fourth workstation 44, at which, for example, the vehicle geometry of the vehicle 10 can be measured (step 54a) and the chassis can be adjusted (step 54b).
  • a fourth vehicle test device 3d for example a test device, is closed at the fourth work station 44 Wheel alignment provided.
  • the newly installed steering angle sensor can be automatically calibrated by the vehicle testing device 3d after the chassis measurement and setting have been completed (step 54d), since the required identification data for the vehicle 10 is already in the VCI 1 are present.
  • the identification data of the vehicle 10 can also already be used for the preparation of the measurement and adjustment of the chassis.
  • the VCI 1 can be disconnected from the vehicle 10 again when the workshop cycle is ended (step 54e).
  • the workshop order can then be completed and the data and result logs of the workshop run can be stored in a central workshop system, for example the central workshop server 45, for reuse when the customer or vehicle 10 visits the workshop again.
  • Figure 4a shows a schematic representation of a method for identifying, diagnosing, maintaining and repairing a vehicle in a workshop via a VCI, a central workshop server with a central diagnostic server device and / or local diagnostic server devices according to a further embodiment of the invention.
  • the procedure after Figure 4a differs from the procedure according to Fig. 4 essentially only in the fact that a group of specific vehicle test devices, here for example only vehicle test device 3b, can be equipped with decentralized diagnostic server devices 2a.
  • the vehicle test devices of the group of specific vehicle test devices can thus establish direct communication with the VCI 1.
  • the central diagnostic server device 2 and / or the workshop server 45 fails, the VCI 1 can still be accessed via the decentralized diagnostic server devices 2a, here for example via the vehicle testing device 3b.
  • Any number of vehicle test devices can be equipped with such a decentralized diagnostic server device 2a.
  • the identification of the vehicle 10 required for the control device communication is carried out only once per workshop visit and is only expanded when required at individual workstations or with individual vehicle test devices. This leads to considerable time savings in the workshop cycle.
  • the vehicle identification data, once recorded, is available at every workstation, since it is carried along by the vehicle 10 via the VCI 1 from workstation to workstation and can be read out centrally via a workshop server 45 with a central diagnostic server device 2.
  • the control software of the vehicle testing device can only activate those functions in the communication with the electronic control devices of the vehicle that are actually required for the respective workstation. This enables simple and practical handling of the respective specific vehicle test devices or universal operating and display units at specific workplaces in the workshop. For the users of the vehicle test devices at the workstations, the necessary qualifications in dealing with control unit communication are reduced, since the communication between the electronic control units in the vehicle and the vehicle test devices can run largely automatically and in the background.
