Abstract

See full text

When a voltage applied to a heater assumes a low-level potential, a control section of a load drive apparatus instantaneously supplies an anomaly judgment current to the heater, and computes the electrical resistance of the heater on the basis of the anomaly judgment current. The control section judges whether or not any of anomalous states of the heater, including at least a deteriorated state of the heater and wiring anomalous states of the heater, has occurred on the basis of the electrical resistance of the heater.
