Abstract
An information processing system includes a first ECU and a second ECU. The first ECU is configured to: communicate with the second ECU; acquire an activation request signal from an external device; determine whether the acquired activation request signal has continued for a prescribed period or more; when the first ECU determines that the activation request signal has continued for the prescribed period or more, identify the external device that has output the activation request signal as an abnormal external device; switch the second ECU to a wake-up mode when the first ECU acquires the activation request signal from the external device that is not the abnormal external device while the second ECU is in a sleep mode; and switch the second ECU to the sleep mode when the first ECU acquires the activation request signal from the abnormal external device.
