RELAY DEVICE
First Claim
1. A relay device including a processing unit and being located between network buses to which a plurality of electronic control devices are communicably connected, whereinthe processing unit is configured to:
- prohibit transfer processing of data from each electronic control device connected to the network bus while software in the relay device is being rewritten by an external device; and
allow transfer processing of prohibition data, which is transmitted from the external device and which indicates at least either one of transmission prohibition of periodic transmission data and storage prohibition of a failure code into each electronic control device by not receiving the periodic transmission data in each electronic control device, to the network buses.

Abstract
While software in a relay device is being rewritten by an external diagnosis device, a processing unit of the relay device prohibits transfer processing of data from each ECU connected to CAN bus and allows transfer processing of data, which is transmitted from the external diagnosis device and which indicates at least either one of transmission prohibition of periodic transmission data and storage prohibition of a failure code into each ECU by not receiving the periodic transmission data in each ECU, to the CAN buses.
