Lexus ES: Adjustment

ADJUSTMENT

PROCEDURE

1. PERFORM BLIND SPOT MONITOR BEAM AXIS CONFIRMATION

HINT:

The blind spot monitor beam axis confirmation is performed to confirm whether the sensor's beam axis is correct, and perform adjustment of the beam axis by using reflector.

(a) 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.

*A	Left Side Of Vehicle	*B	Right Side Of Vehicle
*a	Vehicle Center Line	*b	Rear Bumper
*c	Inspection Area	-	-

Standard:

Location	Measurement
a	1 m (3.28 ft.)
b	5 m (16.41 ft.)
c	6 m (19.68 ft.)

(b) Place the reflector.

(1) 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.

*a	String	*b	Weight
*c	Center	*d	Bilateral Symmetry

HINT:

Lightly flick the string with your fingers several times to confirm that the string is aligned with mark A.

(2) Hang a weight with a pointed tip from the center of the radiator grille (or front panel) emblem, and mark the front center point of the vehicle (point B) on the ground.

*a	String	*b	Weight
*c	Center	*d	Bilateral Symmetry

HINT:

Lightly flick the string with your fingers several times to confirm that the string is aligned with mark B.

(3) Draw a vehicle center line so that it passes through mark A and B (front and rear center points).

*a Vehicle center line

(4) Enlarge and print out the poster shown in the illustration.

*a	Poster	*b	Edge of Rear Bumper
*c	Line C	*d	Vehicle center line

Standard:

Part	Angle
a	52.6°

(5) Attach the printed poster to the floor with the vehicle center line aligned with point A as shown in the illustration.

*a Poster *b Vehicle Center Line

(6) Align a piece of string with line C and mark point D at a distance of 3384 mm (11.1 ft.) from point A.

*a Vehicle Front *b Vehicle Center Line *c String *d Poster

(7) Set the reflector at the point D shown in the illustration below.

SST: 09870-60000

09870-60010

SST: 09870-60040

*A	Left Side Of Vehicle	*B	Right Side Of Vehicle
*a	Vehicle Center Line	*b	Reflector

Standard:

Part	Length
a	3384 mm (11.1 ft.)

(c) Perform the blind spot monitor beam axis display.

(1) Connect the GTS to the DLC3.

(2) Turn the engine switch on (IG).

(3) Turn the blind spot monitor system on.

(4) Turn the GTS on.

(5) 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 RH side and the slave beam is on the LH side.

Body Electrical > Blind Spot Monitor Master > Utility

Tester Display
BSM Master Beam Axis Display

Body Electrical > Blind Spot Monitor Slave > Utility

Tester Display
BSM Slave Beam Axis Display

(6) Check the results displayed for the BSM beam axis display.

Allowable Range:

Item	Blind Spot Monitor Sensor RH	Blind Spot Monitor Sensor LH
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

(d) Perform the blind spot monitor beam axis adjustment.

(1) Enter the following menus: Body Electrical / Blind Spot Monitor Master or Blind Spot Monitor Slave / Utility / BSM Master Beam Axis Adjustment or BSM Slave Beam Axis Adjustment.

Body Electrical > Blind Spot Monitor Master > Utility

Tester Display
BSM Master Beam Axis Adjustment

Body Electrical > Blind Spot Monitor Slave > Utility

Tester Display
BSM Slave 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.

2. PERFORM BLIND SPOT MONITOR SENSOR INSTALLATION CONDITION 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.

(a) Remove the rear bumper assembly.

for Dual Type: Click here

(b) 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

(c) 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.

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

HINT:

The outward facing surface (installation angle) is positive (+) when it faces higher than horizontal.

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

Standard:

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

(d) 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° 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.
