The backup boost converter uses a semiconductor relay. The semiconductor relay also functions as a fuse. When overcurrent is detected, the relay is turned off to protect the circuit.
The backup boost converter supplies battery voltage to help make up for the voltage drop that occurs when the engine is restarted. This prevents the operation of the following equipment from being interrupted due to low battery voltage.
Skid Control ECU
Steering Sensor
Combination Meter Assembly
Body ECU
Radio and Display Receiver Assembly*1
Forward Recognition Camera
Millimeter Wave Radar Sensor Assembly
Air Conditioning Control Assembly*2
*1: Models with display audio system
*2: Models with automatic air conditioning
