An electronic device capable of receiving and a method to transfer data from a tester

摘要

The invention relates to the field of electronic device assisting in the transfer of data from a tester (10) to an electronic control unit ECU (20) in vehicles. The electronic device (14) receives the data from the tester (10) connected through a first bus (12) which has higher data transfer rate, stores the data in a memory unit (16) connectable temporarily. Once the data is transferred to the temporary memory unit (16), the tester (10) is disconnected. The electronic device (14) transfers the data from the temporary memory unit (16) to relevant ECUs (20) using a second bus (18) which has a lower data transfer rate. Once the complete data from the temporary memory unit (16) is transferred to the relevant ECUs (20), the temporary memory unit (16) is removed from the electronic device (14). The same memory unit (16) is used with other electronic devices in other vehicles to transfer data from tester (10) to the ECUs (20).
