ABSTRACT:
A method and an apparatus detect an erroneous connection between a plurality of ignition devices and a fuel injection control device. A first time interval is measured from an input of an ignition signal for a certain cylinder to an input of the next ignition signal and a second time interval from an input of the next ignition signal to an input of a further next ignition signal. An erroneous connection is determined by comparing a relationship between the first time interval and the second time interval with a previously stored normal relationship between the first time interval and the second time interval that are correctly connected in accordance with a predetermined procedure. The erroneous connection is outputted and displayed to a predetermined erroneous connection display device if it is determined that the erroneous connection exists.
