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.

NOTICE:

  • 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 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.

(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.

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

(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.

(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 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

NOTICE:

  • 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.

(a) Remove the rear bumper assembly.
