Wide View Front Monitor System System Description

This system has a front television camera assembly to display the front view of the vehicle on the navigation receiver assembly*1 or radio and display receiver assembly*2.

This system consists of the following components:

1. Parking assist ECU
   

2. Front television camera assembly
   

3. Steering pad switch assembly (wide view front and side monitor switch)
   

4. Navigation receiver assembly*1
   

5. Radio and display receiver assembly*2
   

6. Spiral cable sub-assembly
   

7. Skid control ECU (brake actuator assembly)
   

8. Four wheel drive control ECU
   

9. ECM
   

This system is equipped with a self-diagnosis system, which is operated from a designated window that appears on the display panel, just as in the navigation system or audio and visual system.

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

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 to the wide view front monitor system.

Screen display operation

1. After the display conditions are met when the wide view front and side monitor systems are normally functioning, if the screen is changed from the manual display mode or automatic display mode screen, the wide view front and side monitor screen (H4 mode) or wide view front monitor screen (L4 mode) is displayed as the initial screen.
   

   HINT:

   1. If the shift lever is not in R and the wide view front and side monitor screen is displayed, the course guideline display change switch and automatic display mode set/cancel switch are displayed and the following operations can be performed.
      
   2. For the course guideline display change switch, refer to the following procedures (LandCruiser RM000003EB400YX.html).
      
   3. Automatic display mode set/cancel switch
      
      

      Automatic mode display switch (Indicator in the button)	Display mode

Screen display timer function

1. During manual display mode (when the shift lever is not in R), when the wide view front and side monitor 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 Wide View Front and Side Monitor Switch 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 wide view front and side monitor switch 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 wide view front and side monitor switch 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 wide view front and side monitor switch 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 multi-display 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 minute 30 seconds timer is canceled and the camera screen is displayed for 8 seconds the moment the wide view front and side monitor switch is pressed.

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

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

The components of the wide view front 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 front monitor system will stop functioning.

This wide view front monitor system has a diagnostic function displayed in the navigation receiver assembly*1 or radio and display receiver assembly*2. This function enables the calibration (adjustment and confirmation) of the system (LandCruiser RM0000035DD06LX.html).

The system can check the following items by using the GTS.
