Front view guiding lines
REAR VIEW The rear view image is from the rear camera.
 When the selector lever is in the reverse position, the rear view is displayed. Backing and parking are
improved by the images from Birds-Eye view and Front-S ide view. The rear wide view function allows the
display of an image with a 180 ° horizontal angle.
 Display the vehicle width guiding line and vehicle distance guiding line in Rear view and display the predic- tive course line according to the steering angle (except when using the rear wide view function).
 The predictive course line is not di splayed at the steering neutral position.
 AV control unit is connected to the steering angle s ensor and receives the steering angle signal via CAN
communication. AV control unit is transmits steering angle signal to around view monitor control unit via AV
communication.
 Around view monitor control unit controls the direction and distance of predictive course line according to the
sensor signal from steering angle sensor.
Rear view guiding lines
FRONT-SIDE VIEW
 The front-side view image is from the side camera RH.
 In Front-Side view, display the vehicle distance guiding line and vehicle width guiding line.
 The infrared LED illumination is installed on the door mirror RH to illuminate around the front wheels.

OUTLINE
 BCM incorporates a power saving control function t hat reduces the power consumption according to the
vehicle status.
 BCM switches the status (control m ode) by itself with the power saving control function. It performs the sleep
request to each unit (IPDM E/R, combination meter, dr iver seat control unit, automatic back door control
module, pre-crash seat belt control unit and CAN gat eway) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Stop lamp switch signal Stop lamp switch TCM (CAN) Inputs the stop lamp switch 1
signal and stop lamp switch 2
signal, and transmits it via CAN
communication.

nication.
Horn request signal Low tire pressu

trol unit IPDM E/R (CAN)Received the horn request sig-
nal, transmits the horn reminder

SYSTEM
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
 The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
 BCM receives the sleep-ready signal (ready) from IPDM E/R, combination meter and automatic back door
control module via CAN communication.
 BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
 Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com- munication sleep mode.
 BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
 BCM transmits sleep wake up signal (wake up) to eac h unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
 Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mit wake up signals to BCM with CAN communication to convey the start of CAN communication.
