Adjustment [10/2022 - 11/2023]: Procedure

PERFORM BLIND SPOT MONITOR BEAM AXIS CONFIRMATION

HINT:

The blind spot monitor beam axis confirmation is performed to confirm whether the sensor beam axis is correct, and to adjust the beam axis by using a reflector.

When performing the blind spot monitor beam axis confirmation, move the vehicle to a place where the space shown in the illustration can be secured.

NOTE:

Perform this inspection on level ground.
Make sure that there are no metal objects around the vehicle or on the ground.
Unload the vehicle before beginning the inspection.
Confirm that the tire pressure is correct before beginning the inspection.
Do not place any objects other than the reflector (such as a large metallic object) in the inspection area or allow people to enter the inspection area (W 6 m [19.68 ft.] x L 6 m [19.68 ft.] x H 4 m [13.12 ft.]) shown in the illustration.

Place the reflector.

Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.

Set the reflector as shown in the illustration so that the center of the triangular pyramid faces the blind spot monitor sensor.

Perform the blind spot monitor beam axis display.

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the blind spot monitor system on.
Turn the GTS on.

Enter the following menus: Body Electrical / Blind Spot Monitor Master or Blind Spot Monitor Slave / Utility / BSM Master Beam Axis Display or BSM Slave Beam Axis Display.

HINT:

The master beam is on the LH side and the slave beam is on the RH side.

Angle	-3.6 to +3.6°	-3.6 to +3.6°

HINT:

If the displayed results are outside the permissible range, the following are possible causes. Therefore, implement countermeasures, check the blind spot monitor beam axis and perform the procedure again.

Possible Causes	Countermeasure
Incorrect SST (reflector) position	Check the position of SST (reflector) and checking space and perform the procedure again
A metallic object is located in the vicinity of the checking space	Check the position of SST (reflector) and checking space and perform the procedure again
The blind spot monitor sensor installation is abnormal	Check the installation condition of the blind spot monitor sensor

Perform the blind spot monitor beam axis adjustment.

HINT:

When values on the axis display are in the allowable range, performing this adjustment compensates for any deviation from the normal value.

PERFORM BLIND SPOT MONITOR SENSOR INSTALLATION CONDITION INSPECTION

NOTE:

Perform this inspection on level ground.
Unload the vehicle before beginning the inspection.
Confirm that the tire pressure is correct before beginning the inspection.

HINT:

The blind spot monitor sensor installation condition inspection is performed to confirm whether the sensor is perpendicular to the floor surface (+/-2.2°) by using a digital angle gauge, and that the sensor is 46 to 54° from the line parallel to the vehicle center line.

Remove the rear bumper assembly.
Refer to REMOVAL [10/2022 - 11/2023]

Place the digital angle gauge on a level (gradient within 1%) and perform zero-point adjustment as shown in the illustration.

*a	(+)	*b	(-)
*c	When Storing Zero Point	*d	After Storing Zero Point, Indicates 90° When Fully Horizontal

Set the digital angle gauge to the outward facing surface of the blind spot monitor sensor as shown in the illustration, and check that the perpendicular angle of the blind spot monitor sensor is within the permissible range.

*1	Blind Spot Monitor Sensor
*a	Digital Angle Gauge
*b	Outward Facing Surface

NOTE:

The sensor angle is the measured sensor angle subtracted from 90°.

*a	(+)
*b	(-)
*c	Horizontal Line
*d	Digital Angle Gauge
*e	Outward Facing Surface

HINT:

The digital angle gauge should indicate 90° when turned on its side.
The outward facing surface (installation angle) is positive (+) when it faces higher than horizontal.

Standard

Item	Allowable Range
Blind Spot Monitor Sensor LH	+2.2 to -2.2°
Blind Spot Monitor Sensor RH	+2.2 to -2.2°

Using the sensor installation stud bolt center lines as a reference, check that the stud bolts are as shown in the illustration.

Standard

Dimension	Specified Value
a	108 mm (4.25 in.)
y	78 to 87 mm (3.07 to 3.43 in.)

Degree	Specified Value
A	46 to 54°

*A	Vehicle Rear (LH)
*a	Vehicle Front
*b	Vehicle Rear
*c	Vehicle Center Line
*d	Stud Bolt
*e	Stud Bolt Center Line
*f	Line Parallel to Vehicle Center Line

HINT:

If the results are not as specified, it is possible that the blind spot monitor sensor installation area (frame, stud bolt) is deformed, so make corrections as necessary.
