Abstract
An in-vehicle device connected to an ECU installed in a vehicle includes: a PHY unit which converts a signal from the communication line into a digital signal; an oscillation circuit which outputs a first oscillation signal; a detection circuit which outputs a detected value corresponding to a difference between a frequency of the first oscillation signal and a frequency of a second oscillation signal; a switch unit which switches between a first state and a second state; and a control unit configured to control the switch unit. The control unit controls the switch unit to be in the first state if the detected value differs from a normal value corresponding to a difference between the frequency of the first oscillation signal and a frequency of a third oscillation signal and controls the switch unit to be in the second state if the detected value is within the predetermined value.
