STRUCTURE

• The CAN bus line consists of two lines, CAN_L and CAN_H (CAN Low and CAN High, respectively), as well as two terminal resistors (A twisted-pair cable, highly resistant to noise, is used for the communications line).
  
• The CAN bus line connecting the two terminal resistors is the main bus line, and the CAN bus line connecting each ECU is the sub-bus line.
  
• The terminal resistors are installed in the engine-ECU and ETACS-ECU to stabilize communication signals (The terminal resistance is set at approximately 120 Ω).
  
• The following components are connected in the CAN bus line as follows.
  


• ETACS-ECU
  
• ASC-ECU
  
• EPS-ECU
  
• Combination meter
  
• Steering wheel sensor
  
• G and yaw rate sensor
  
• Battery management unit (BMU)
  
• On board charger/DC-DC converter
  
• Compressor/heater controller
  
• Electric motor control unit (EMCU)
  
• EV-ECU
