SYSTEM DESCRIPTION
GENERAL
(a) The blind spot monitor system has a blind spot monitor function and RCTA function.
(1) Blind spot monitor function
This function uses quasi-millimeter wave radar to detect vehicles that are traveling in adjacent lanes in the areas that are not visible using the outer rear view mirror assemblies (blind spots) and vehicles that are approaching rapidly from up to 60 m behind this vehicle in the areas that are not visible using the outer rear view mirror assemblies (blind spots).
The function advises the driver of the existence of a vehicle by illuminating the outer rear view mirror indicator on the outer rear view mirror assembly.
(2) RCTA function
FUNCTION OF COMPONENTS
Component |
Function |
---|---|
Blind Spot Monitor Sensor |
|
Outer Rear View Mirror Assembly
|
Turns on or blinks the indicator based on a signal from the blind spot monitor sensor. |
Steering Pad Switch Assembly |
|
RCTA Buzzer (Blind Spot Monitor Buzzer) |
Sounds based on a signal from the blind spot monitor sensor. |
Combination Meter Assembly
|
|
Main Body ECU (Multiplex Network Body ECU) |
Transmits the destination information and the dimmer signal to the blind spot monitor sensor via CAN communication. |
Skid Control ECU |
Transmits the vehicle speed signal to the blind spot monitor sensor via CAN communication. |
ECM |
Transmits the shift position signal (R) to the blind spot monitor sensor via CAN communication. |
Steering Sensor |
Detects the angle of the steering wheel and transmits the resulting signals to the blind spot monitor sensor via CAN communication. |
Airbag Sensor Assembly |
Transmits the yaw rate signal to the blind spot monitor sensor via CAN communication. |
OPERATION DESCRIPTION
(a) Operation description of the blind spot monitor function
(1) Operation conditions:
(2) Conditions in which a sensor can detect a vehicle
The blind spot monitor function indicates detection of a vehicle in the detection area when either condition is met:
HINT:
The greater the difference in speed between the vehicle and the detected vehicle is, the farther away the other vehicle will be when the notification is given.
(3) Detection area
Vehicles in the following areas can be detected:
*a |
Within Approximately. 3.5 m (11.48 ft.) from Side of Vehicle |
*b |
Within Approximately. 1 m (3.28 ft.) Forward of Rear Bumper |
*c |
Within Approximately. 3 m (9.84 ft.) Behind Rear Bumper |
*d |
Within Approximately. 3 m (9.84 ft.) to 60 m (196.86 ft.) from Rear Bumper |

Detection Area (for Vehicle in Blind Spot) |

Detection Area (for Rapidly Approaching Vehicle from Behind) |
(b) Operation description of the RCTA function
(1) Operation conditions:
(2) Conditions in which a sensor can detect a vehicle
The RCTA function indicates detection of a vehicle in the detection area when both conditions are met:
(3) Detection area
Vehicles in the following areas can be detected:
*a |
Within Approximately. 5.5 to 20 m (18.05 to 65.62 ft.) from Side of Vehicle (detection area changes according to vehicle speed) |
*b |
Within Approximately. 6 m (19.69 ft.) Behind Rear Bumper |

Detection Area |
HINT:
"RCTA system" must be equipped with "Rear view monitor", because "Blind Spot Monitor Sensor" cannot detect a vehicle right behind.
OPERATION OF OUTER REAR VIEW MIRROR INDICATOR AND RCTA BUZZER (BLIND SPOT MONITOR BUZZER)
(a) Initial check
(1) When the blind spot monitor system is turned on with the ignition switch to ON, the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds and the RCTA buzzer (blind spot monitor buzzer) sounds for 1 second.
(2) When the ignition switch is turned from off to ON with the blind spot monitor system on, the outer rear view mirror indicators on the outer rear view mirror assembly illuminate for 3 seconds.
(b) Operation for each function
(1) Operation for blind spot monitor function
(2) Operation for RCTA function
*a |
0.125 Seconds |
*b |
2.5 Seconds |
*c |
0.1 Seconds |
*d |
0.4 Seconds |
*e |
2.3 Seconds |
