摘要： A self-diagnosis method for an ignition coil includes receiving and confirming a current flag (C/F) signal through monitoring of primary current of an ignition coil; monitoring secondary current of the ignition coil upon receiving the C/F signal and confirming whether a fault flag (F/F) signal for determining whether misfire of the ignition coil occurs is input; and determining whether an abnormal signal of the ignition coil is generated based on the result of confirming the C/F signal and the F/F signal respectively.

摘要： An electronic gear shift apparatus may include a housing, an up switch installed in a space portion formed by opening an upper side of the housing, a down switch installed in the space portion formed by opening the upper side of the housing, and spaced apart from the up switch so as to face the up switch, a touchpad installed below the up switch and the down switch, and a gear shift stage display device installed on a surface of the housing, and displaying a position of a gear shift stage, in which when the up switch is pushed upward or the down switch is pushed downward in a state in which the finger is in contact with the touchpad, the gear shift stage may be changed in a direction of an upper gear shift stage or a lower gear shift stage of the gear shift stage display unit.
