  1. OPERATION EXPLANATION 
    1. The reverse position signal is sent from the shift position switch to the parking assist ECU when the shift position is moved to R.
    2. An appropriate steering angle and timing information can be provided for the driver. This is based on the information from the steering angle sensor signal and the vehicle angle data signal that are sent to the parking assist ECU.

      HINT: 

      The steering angle sensor signal is used to control parking assist only for estimated guide line mode.

  2. COMMUNICATION SYSTEM OUTLINE 
    1. CAN communication system
      1. The panoramic view monitor system uses CAN communication for data communications between the parking assist ECU and each ECU.
      2. If a problem occurs in the CAN communication line, the parking assist ECU outputs a CAN communication malfunction DTC. (To check, use the Techstream.)

        Refer to DTC CHECK / CLEAR [10/2023 - ] 

      3. If a CAN communication line malfunction DTC is output, repair the malfunction in the communication line and troubleshoot the panoramic view monitor system when data communication is normal.
