御装置。 A diesel engine control device configured to perform preheating control of a glow plug has an output port that enters a high impedance state when it becomes inoperable due to a drop in drive voltage, and a separate output port. A microprocessor that outputs a control signal for preheating control of the glow plug from a port, a means for outputting a starting signal indicating that the diesel engine is in a starting state, and turning on and off energization to the glow plug. a relay means and an output port responsive to the control signal and the start signal whose output becomes high impedance when the microprocessor is reset to a glow plug when the diesel engine is in a high impedance state and the diesel engine is in a starting state; energization is performed regardless of the control signal, and when the diesel engine is not in a starting state, the control circuit provides a relay drive signal to the relay means for energizing the glow plug in accordance with the control signal. A diesel engine control device characterized by:
