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.
