POWER CONNECTING CIRCUIT BETWEEN IGNITION SWITCH AND A PLURALITY OF ECUS

摘要

The present invention relates to an ignition switches and some significant power connection circuit Lee, what is connected to the quantity that geusyeon switches u is Li, it has a pull down resistor to perceive the continuation state of ignition switch, headlight washer motor relay and be connected to ignition switch, one end be connected to that headlamp switch of ground and washer switch Lee continuation state include oil have each pull-up resistor for detecting and; Headlight relay and washer motor and pull-up resistance are significantly that Lee is characterized in that, anode is connected a common diode pair and is connected by being provided with multiple connectors of reverse current prevention. To, quantity more than Li, it is used to feel the continuation state of ignition switch, it is operatively coupled to the power supply wiring between multiple Lee of the switch of ignition switch reverse current and adds lubricating oil for the sensing operation state of different driving power Lee, by preventing from significantly flowing, failure can be prevented from.
