1. An apparatus for detecting a malfunction configured to detect a malfunction of an indicator configured to display a charging state of a vehicle battery according to a control signal, the apparatus comprising:
an interrupt generation unit configured to generate an interrupt signal when the control signal satisfies a preset predetermined event;
a voltage detection unit configured to convert an analog value of the control signal to a digital value to detect a voltage value of the control signal; and
a determination unit configured to determine at least one among whether a malfunction occurrence is indicated by the indicator and a malfunction type based on at least one among whether the indicator operates, whether the interrupt signal is generated, and the voltage value of the control signal,
wherein the determination unit is configured to determine whether a malfunction occurrence is indicated by the indicator when the interrupt signal is not generated while the indicator operates.
