Abstract: In an electronic control unit, high-heat-generating devices are mounted on a first surface or a second surface of a board, a heat-dissipating member is located facing the first surface of the board, and a heat-conducting member is located between the board and the heat-dissipating member. The heat-conducting member is in contact with the high-heat-generating devices to transfer heat of the high-heat-generating devices to the heat-dissipating member. A ratio of the number of the high-heat-generating devices mounted on the board to the number of the high-heat-generating devices arranged inside a first limited region of the first surface or a second limited region of the second surface is greater than a predetermined ratio. The second limited region is located at a position corresponding to the first limited region.

Abstract: A malfunction detection method detects a malfunction in an electronic control device. The electronic control device includes a normal power supply terminal connected to a normal power supply mounted on a vehicle, a starting power supply terminal connected to a starting power supply, a controller activated by supply of a normal voltage, and a wake-up circuit having a wake-up switch to open and close a power supply path from the normal power supply terminal to the controller. The wake-up circuit turns on the wake-up switch when a starting voltage input to the starting power supply terminal is equal to or greater than an ON threshold. The malfunction detection method includes determining by the controller that the wake-up switch has an ON sticking malfunction when the normal voltage is equal to or greater than a threshold and the starting voltage is less than the ON threshold.
