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).
  
• ECUs and sensors are connected in the CAN bus line as follows.
  


• Engine-ECU
  
• A/T-ECU <A/T>
  
• Immobilizer-ECU
  
• A/C-ECU <vehicles with automatic-A/C>
  
• ABS-ECU <vehicles with ABS>
  
• ASTC-ECU <vehicles with ASTC>
  
• Steering wheel sensor <vehicles with ASTC>
  
• G and yaw rate sensor <vehicles with ASTC>
  
• CAN adapter <vehicles with RV meter>
  
• Multi display station <vehicles with multi display station>
  
• ETACS-ECU
