Electronic control device

The first control unit (57) is started by supplying power from the first power supply path (51) and is turned into a start-up state. The second control unit (67) supplies power from a second power supply path (61) different from the first power supply path (51). A power switch (52) is provided in th...

description The first control unit (57) is started by supplying power from the first power supply path (51) and is turned into a start-up state. The second control unit (67) supplies power from a second power supply path (61) different from the first power supply path (51). A power switch (52) is provided in the first power supply path (51). The power switch (52) is turned on when a predetermined switching command is a connection command (C) to enable energization of the first power supply path (51), and is turned off when the switching command is a disconnection command to disable energization of the first power supply path (51). The first control unit (57) transmits a start signal (alpha) indicating whether the first control unit (57) is in a start state or a stop state. The second control unit (67) determines that the power switch (52) is abnormal on condition that the activation signal (alpha) indicates a stop state when the switching command is a connection command (C) or on condition that the activation signal (alp
