Toyota prius 3rd gen stop light control relay assembly (A28) (895A0-47020) Toyota Prius 3 rd Generation (XW30) Stop Light Control Relay Assembly Wiring Guide: DIY Pinout Diagram Last Updated: What is: The Stop Light Control Relay Assembly (also called the Stop Lamp Relay or Brake Light Relay) is an electrical component in a vehicle’s lighting and braking system. It helps control the power supply to the brake lights when you press the brake pedal. 1. Introduction       The Toyota Prius 3rd Generation Stop Light Control Relay is a key electrical component that manages the operation of the brake lights. When the brake pedal is pressed, the relay activates to supply power from the battery to the stop lamps, ensuring clear and timely illumination for safety. It works in coordi...

Toyota prius 3rd gen Occupant Detection ECU (W2)(W3) 89952-47021 Toyota Prius 3 rd Generation (XW30) Occupant Detection ECU Assembly Wiring Guide: DIY Pinout Diagram Last Updated: What is: TheThe Occupant Detection ECU (Electronic Control Unit) is a small control computer that is part of a vehicle’s airbag system. It receives signals from the occupant detection sensors located in the seats to determine whether a seat is occupied and, if so, the size and weight of the occupant. This information helps the system decide whether to deploy the airbag and at what intensity during a collision, improving passenger safety and preventing unnecessary airbag deployment. 1. Introduction The Toyota Prius 3rd generation Occupant Detection ECU is a safety control unit located under the passenger seat. It processes signals from weight sensors in the seat cushion to identify whether th...
