FUNCTION OF COMPONENTS

1. The parking assist ECU controls the system by using information from the following components.

   Item	Function
   Parking Assist ECU	Turns the side television camera assembly on or off based on parameters such as the display settings, the front and side monitor main switch signal, the shift signal and the vehicle speed signal. Transmits the wide view front and side monitor, side monitor, or wide view front monitor signals to the multi-media module receiver assembly based on parameters such as the display settings, the front and side monitor main switch signal, the shift signal and the vehicle speed signal. Depending on the display settings, renders the output display for the wide view front and side monitor, the side monitor, or the wide view front monitor, and outputs them to the screen of the multi-display assembly. With the video feed from the side television camera assembly showing the vehicle's left-side surroundings as a base, uses vehicle information such as the signal from the steering angle sensor to calculate and overlay a composite image and output this to the screen of the multi-display. Renders each configuration page in the diagnosis window and outputs the screen to the multi-display assembly. When the outer mirror retraction signal is received, terminates the side camera collimation/alignment. Stores each configuration setting from the diagnosis window.
   Multi-media Module Receiver Assembly	Communicates with the parking assist ECU through AVC-LAN communication.
   Multi-display Assembly	This touch panel display is used to view and interact with the wide view front and side monitor, side view monitor, wide view front monitor, and diagnosis screens.
   Side television camera assembly	Generates a video feed showing the passenger side of the vehicle and transmits the video to the parking assist ECU.
   Front and Side Monitor Main Switch Assembly	Operating the switch sends a signal to the parking assist ECU.
   Outer Mirror Switch Assembly	Transmits outer mirror retraction signal to parking assist ECU.
   Steering Sensor	Transmits steering angle signal and sensor status signal to multi-display via CAN communication.
   Steering Control ECU*	Sends the VGRS relative angle and vehicle condition to the parking assist ECU through CAN communication.
   Master Cylinder Solenoid (Skid Control ECU Assembly)	Sends the inner brake information and ABS ACT information to the parking assist ECU through CAN communication.
   Four Wheel Drive Control ECU	Sends the L4 condition signal to the parking assist ECU through CAN communication.
   ECM	Sends the vehicle condition, 2WD/4WD information and shift position information to the parking assist ECU through CAN communication.

3. Screen display timer function

   
   

   1. During manual display mode (when the shift lever is not in R), when the front and side monitor main switch is pressed and the following conditions are met, the wide view front and side monitor screen is displayed for a certain period of time even when the vehicle speed is more than 12 km/h (7.5 mph).

      

      Screen Display Time	Time when Front and Side Monitor Main Switch Assembly is Pressed	Change in Vehicle Speed	Timer Operation Time	Note
      A B	12 km/h (7.5 mph) or less	12 km/h (7.5 mph) or less	8 seconds	When the front and side monitor main switch assembly is pressed with the vehicle speed at 12 km/h (7.5 mph) or less, the camera screen is displayed for 8 seconds from the moment the switch is pressed. After this, if the vehicle speed increases to above 12 km/h (7.5 mph), the camera screen is not displayed.
      C	More than 12 km/h (7.5 mph)	More than 12 km/h (7.5 mph)	8 seconds or 4 minutes and 30 seconds	When the front and side monitor main switch assembly is pressed while the vehicle speed is more than 12 km/h (7.5 mph), the camera screen is displayed for 4 minutes and 30 seconds the moment the switch is pressed (when the vehicle speed is more than 12 km/h (7.5 mph) after 4 minutes and 30 seconds elapse from the time the switch is pressed).
      D	More than 12 km/h (7.5 mph)	More than 12 km/h (7.5 mph) → 12 km/h (7.5 mph) or less → More than 12 km/h (7.5 mph)	8 seconds or 4 minutes and 30 seconds	When the front and side monitor main switch assembly is pressed while the vehicle speed is more than 12 km/h (7.5 mph), the screen display timer operates and the camera screen is displayed. However, after the vehicle speed decreases to 12 km/h (7.5 mph) or less within 4 minutes and 30 seconds (after 8 seconds have elapsed), if the vehicle speed increases to more than 12 km/h (7.5 mph) again, the screen switches to the navigation or information setting screen. After the vehicle speed decreases to 12 km/h (7.5 mph) or less within 8 seconds, if the vehicle speed increases to more than 12 km/h (7.5 mph) again, the 4 minutes 30 seconds timer is canceled and the camera screen is displayed for 8 seconds the moment the front and side monitor main switch assembly is pressed.

4. Display conditions for automatic display mode

   
   

   1. In automatic display mode, the screen display is automatically displayed according to driving conditions when the following conditions are met and the wide view front and side monitor systems are normally operating.

      

      Vehicle Condition	Multi-display Assembly Display Screen	Shift Lever	Vehicle Speed	Display Screen
      Stopped → Driving	Navigation screen or information setting screen	Not in P or R	12 km/h (7.5 mph) or less	Navigation screen or information setting screen → Wide view front monitor and side monitor screen*
      Driving → Stopped		Not in P or R	10 km/h (6.2 mph) or less	Navigation screen or information setting screen → Wide view front monitor and side monitor screen*

      
      

      • *:The conditions to change the screen after the display screen changes automatically are the same as in manual display mode.

5. Off-road turn assist function

      *a	Line Indicating Travel Path

      With the off-road turn assist function on, the path traveled is displayed as dotted lines on the front screen. In this state, the vehicle may not move exactly as the front lines indicate. (The lines indicate the direction the front wheels are turned. However, with the off-road assist function on, the vehicle turns using a difference in drive force between the left and right wheels.)

OPERATION EXPLANATION

1. The front and side monitor main switch ON signal is sent from the main switch to the parking assist ECU.

   After receiving the front and side monitor main switch ON signal, the parking assist ECU switches the display signal for the display and navigation module display from the navigation system to the side monitor system.

COMMUNICATION SYSTEM OUTLINE

1. The components of the side monitor system communicate with each other through the AVC-LAN. If a short circuit or open circuit occurs in the AVC-LAN, communication is interrupted and the side monitor system will stop functioning.

DIAGNOSTIC FUNCTION OUTLINE

1. This side monitor system has a diagnostic function displayed in the parking assist ECU. This function enables the calibration (adjustment and confirmation) of the system Click here.

2. The system can check the following items by using the intelligent tester.
