EC-28 < SYSTEM DESCRIPTION > [QR25DE] COMPONENT PARTS Refrigerant Pressure Sensor INFOID:0000000011277846 The refrigerant pressure sensor is installed at the condenser of the air conditioner system. The sensor uses an electrostatic volume pressure transducer to convert refrigerant pressure to voltage. The voltage signal is sent to ECM, and ECM controls cooling fan system. Stop Lamp Switch & Brake Pedal Position Switch INFOID:0000000011277847 Stop lamp switch and brake pedal position switch are installed to brake pedal bracket. ECM detects the state of the brake pedal by those two types of input (ON/OFF signal). ASCD Steering Switch INFOID:0000000011277848 ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation of switch, and determines which button is operated. Information Display INFOID:0000000011277849 The operation mode of the ASCD is indicated on the information display in the combination meter. ECM transmits the status signal to the combination meter via CAN communication according to ASCD opera- tion.
