Abstract
Disclosed are a method and a device for indicating the malfunction of an apparatus for generating injection control pulses for a fuel injection system. The method compares relatively narrow trigger pulses derived from ignition pulses with the fuel injection control pulses. When the injection control pulses coincide with the trigger pulses, no indication is present. Only when an injection control pulse is missing does the trigger pulse prevail and trigger a bistable switching circuit which activates an optical or acoustical indicator.
