System and Method for Motor Vehicle Diagnosis and Vehicle Reception
First Claim
1. A method for transmitting diagnosis data from a vehicle to a customer reception in a service business, wherein:
- an onboard vehicle diagnosis system for ascertaining, storing and transmitting is used to transmits said data from onboard components to offboard component;
a computer system in the service business, which has an offboard communication module, uses a dedicated channel of a radio interface to send a connection request to the ready-to-receive onboard communication module in the vehicle; and
the connection request is accepted by the onboard communication module only if a pre-arranged identifier is also transmitted when communication is set up.

Abstract
A vehicle diagnosis system for ascertaining, storing and transmitting diagnosis data from control units in a motor vehicle to a computer outside of the motor vehicle has components which are inside of the vehicle and components which are outside of the vehicle. The onboard components are capable of autonomously requesting diagnosis data from control units, buffer-storing the diagnosis data and of transmitting the diagnosis data to offboard components. The offboard components can be used to configure the onboard components, to visually display the transmitted data and to forward said data to subsequent systems. Access is effected using a communication module, which is preferably implemented in a diagnosis control unit with a dedicated gateway and which is not the control unit for the central locking. A gateway for diagnosis applications is present in the vehicle in the case of vehicles with a diagnosis CAN bus or with another diagnosis bus.
