Claim 18:
19. The open-circuit diagnosis method of claim 17,
wherein the electric load is in plural to include a plurality of electric loads, and
wherein the determining of whether the electric load is driven with the output power of the second power supply alone includes:
determining an amount of power consumption based on power supplied to each of the electric loads;
identifying an amount of decrease in a battery state of charge (SOC) value of the second power supply using a sensor;
determining whether a difference between the amount of power consumption and an amount of the battery SOC value is within a tolerance range; and
concluding that there is the open-circuit fault between the first power supply and the power distribution device upon determining that the difference is within the tolerance range.
