WARNING: This page is about a different car, the 2008 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
  1. COMMUNICATION STOP MODE TABLE 
    1. Check that there is no open circuit in the CAN main bus line, short between the lines, or short to +B in the "CHECK CAN BUS LINE". Select "CAN Bus Check" on Techstream via the CAN VIM.
    2. Check that the communication stop mode of the ECUs or sensors is not displayed among the following: "Engine", "ECT", "Cruise Control", "ABS / VSC / TRAC", "Yaw Rate/ Deceleration Sensor", "Steering Angle Sensor", and "Gateway".
      NOTE:
      • Systems using the CAN communication system differ according to optional settings. Check which ECUs or sensors are installed on the vehicle.
      • Non-installed ECUs or sensors are not displayed. Be careful not to consider that they are in communication stop mode.
      • If 2 or more ECUs or sensors are not displayed on Techstream via the CAN VIM, perform troubleshooting for communication stop mode for each no displayed ECU or sensor. (Either side of the CAN bus lines may be open.)
