An apparatus for detecting an error in a motor and valve driving circuit is provided to prevent abnormal operation by interrupting power applied to a driving unit when an error occurs in the driving unit. An apparatus for detecting an error in a motor and valve driving circuit comprises a first switch(FET1) for supplying battery power to valves(5) and a second switch(FET2) for supplying the battery power to a motor(4). A main control unit(1) outputs a motor driving signal or a valve driving signal for driving the motor or the valves. A driving unit outputs first and second switch control signals for controlling the first and second switches in response to the output signal of the main control unit. A monitor circuit monitors the first and second switch control signals output from the driving unit to provide the signals to the main control unit. The monitor circuit comprises a first monitor unit(6-1) and a second monitor unit(6-2). |
