System Description [08/2015 - 08/2019]

1. This system has a front television camera assembly to display the front view of the vehicle on the multi-display 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. Multi-media module receiver assembly
   5. Multi-display assembly
   6. Spiral with sensor cable sub-assembly
   7. Skid control ECU (brake actuator assembly)
   8. Four wheel drive control ECU
   9. ECM
3. 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.

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 multi-display assembly from the multi-media module receiver assembly to the wide view front monitor system.

      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.
