Abstract: The present invention relates to an apparatus for detecting an anomalous condition of a cooling motor fan to be mounted on a vehicle. The anomalous condition detecting apparatus includes a detector for detecting a pair of positive and negative terminals of a motor of the motor fan and a decision circuit for deciding whether an anomalous condition exists or not based on a voltage detected between the terminals. For example, an external resistor is provided between the positive terminal of the motor and the power source, the negative terminal of the motor is earthed, a voltage between the terminals of the motor is detected as a potential of the positive terminal, and the decision circuit decides that an anomalous condition exists when the potential of the positive terminal is smaller than a predetermined value in a state that a drive signal of the motor fan is being output. Accordingly, it is possible to detect an anomalous condition of the motor fan at low cost.
