Method for Repairing Vehicle Electronics of a Motor Vehicle
First Claim
1. A method for repairing vehicle electronics of a motor vehicle, the vehicle electronics containing a plurality of control units storing software and a configuration code of the vehicle electronics describing a configuration of the vehicle electronics in terms of hardware and software being stored in at least one of the control units, the control units including a main control unit and at least two additional control units, which comprises the steps of:
- before replacing at least one defective control unit with a new control unit, checking if the configuration of the vehicle electronics changes due to a replacement of the defective control unit with the new control unit;
if, during the checking as to whether the configuration of the vehicle electronics changes due to the replacement of the defective control unit, it is determined that the configuration of the vehicle electronics does not change, replacing the defective control unit in terms of hardware with the new control unit;
after the defective control unit has been replaced in terms of hardware by the new control unit, checking whether the new control unit has to be programmed in terms of software, if it is determined that the new control unit does not have to be programmed in terms of the software, reading out an actual state from all of the control units and checking whether the actual state corresponds to the configuration code of the vehicle electronics; and
if, during the checking as to whether the actual state of the control units corresponds to the configuration code of the vehicle electronics, it is determined that the actual state corresponds to the configuration code, ending the repair.

Abstract
A method is provided for repairing vehicle electronics containing a plurality of control units on which software and a configuration code describing the configuration of the vehicle electronics in terms of hardware and software is stored. Before a defective control unit is replaced, it is checked whether the configuration of the vehicle electronics changes due to the replacement unit. If the configuration of the vehicle electronics does not change, the defective control unit is replaced. After the defective control unit has been replaced, it is checked whether the new control unit has to be programmed. If the new control unit does not have to be programmed, the actual state is read out from all the control units and it is checked whether the actual state corresponds to the configuration code of the vehicle electronics. If the actual state corresponds to the configuration code, the repair is ended.
