摘要： An electrical system may include an electronic control unit (ECU), a load driver connected to the ECU and configured to selectively provide a first electrical connection between a power source and a load, and/or a secondary power circuit connected to the ECU and configured to selectively provide a second electrical connection between said power source and said load. The secondary power circuit may include a wake-up circuit including a wake-up circuit switch, a trigger circuit including a trigger circuit switch, a sensing circuit including a sensing circuit switch; a switching circuit including a switching circuit switch; and/or a disable circuit connected to the ECU. The ECU may be configured to control the disable circuit to selectively open the switching circuit switch. The disable circuit may include a first disable circuit switch connected to ground and a second disable circuit switch connected to the switching circuit switch.
