| ECM | Transmits the accelerator pedal position signal, engine speed signal to ADAS control unit via CAN communication |
| TCM | Transmits the current gear position signal and shift position signal to ADAS control unit via CAN communication |
| Around view monitor control unit | Receives the BCI warning signal via ITS communication, and indicate the yellow/red frame on the front display. |
| Front display unit | Displays the various system screen signals according to the priority level received via CAN communication |
| Accelerator pedal actuator | Receives signal from ADAS control unit to push up accelerator via ITS communication. |
| Sonar control unit | Receives a warning buzzer signal request from the ADAS control unit via ITS communication and sounds buzzer in sonar control unit. |
| AV control unit | AV control unit transmits the system selection signal to the ADAS control unit via CAN communication |
| Steering angle sensor | Measures the rotation amount, rotation speed, and rotation direction of steering wheel, and then transmits them to ADAS control unit via CAN communication |

BACK-UP COLLISION INTERVENTION SYSTEM OPERATION DESCRIPTION
- ADAS control unit enables Back-up Collision Intervention system.
- The BCI system is automatically turned ON every time the engine is started.
- Combination meter turns Back-up Collision Intervention ON indicator ON/OFF according to the signals from ADAS control unit via CAN communication.
- Side radar detects a vehicle approaching, and transmits the vehicle detection signal to ADAS control unit via ITS communication.
- Side radar receives vehicle speed signal from ADAS control unit and changes its detecting function.
- ADAS control unit starts the control as follows, based on a vehicle detection signal.
Operation Condition of Back-up Collision Intervention System
ADAS control unit performs the control when the following conditions are satisfied.
- Back-up Collision Intervention: ON
- When the vehicle is moving in reverse at 8 km/h (5 MPH) or less.
Note. When the Back-up Collision Intervention system setting on the navigation screen is ON.
DISPLAY AND WARNING OPERATION
| Vehicle condition/Driver's operation | Action | |||||||
|---|---|---|---|---|---|---|---|---|
| Selector lever position | Back-up Collision Intervention system | BCI ON indicator | BCI OFF indicator | Vehicle speed | Status of vehicle detection within detection area | Accelerator pedal control | Brake control | Buzzer |
| Other than "R" position | OFF | OFF | OFF | OFF | OFF | |||
| "R" position | OFF | OFF | ON | OFF | OFF | OFF | ||
| ON | ON | OFF | Vehicle speed = 0 km/h (0 MPH) | Vehicle is detected | OFF | OFF | ON | |
| 0 km/h (0 MPH) < Vehicle speed < 8 km/h (5 MPH) | Vehicle is detected | ON | ON | ON | ||||
| 8 km/h (5 MPH) < or = Vehicle speed | Vehicle is detected | OFF | OFF | OFF | ||||
Note. When the following conditions are satisfied, the Back-up Collision Intervention system will be turned off automatically, a beep will sound. The Back-up Collision Intervention system will not be available until the conditions no longer exist. When the accelerator pedal actuator detects that the internal motor temperature is high [over approximately 100°C (212°F)]. When side radar blockage is detected.
DESCRIPTION
The DTC is displayed on the information display by operating the ICC steering switch.

Always perform the Back-up Collision Intervention system action test to check that the system operates normally after replacing the side radar (left or right), or repairing any Back-up Collision Intervention system malfunction.
| WARNING | Be careful of traffic conditions and safety around the vehicle when performing road test. |
| CAUTION | Fully understand the following items well before the road test; Precautions: Refer to " PRECAUTION FOR BACK-UP COLLISION INTERVENTION ". System description for Back-up Collision Intervention: Refer to " SYSTEM DESCRIPTION ". Normal operating condition: Refer to " DESCRIPTION ". |
ADAS control unit judges the gear position based on the following signals.
- Current gear position signal transmitted from TCM via CAN communication.
- Value of gear ratio calculated from input speed signal transmitted from TCM via CAN communication.
- Value of gear ratio calculated from the vehicle speed signal transmitted from ABS actuator and electric unit (control unit) via CAN communication.
SIDE RADAR LH: Description

The switch does not turn ON
- When the BCI system setting is ON and BCI system is OFF, the BCI ON indicator does not illuminate even if the BCI switch is depressed.
The switch does not turn OFF
- When the BCI system setting is ON and BCI system ON, the BCI OFF indicator does not illuminate even if the BCI switch is depressed.
- BCI system setting is not selectable on the navigation screen.
- Back-up Collision Intervention system setting is not selectable on the navigation screen. NOTE: When the ignition switch is in ACC position, Back-up Collision Intervention system settings cannot be changed. "Back-up Collision Intervention" is not indicated on the navigation screen. The switching between ON and OFF cannot be performed by operating the navigation system. The item "Back-up Collision Intervention" on the navigation screen is not active.
