Toyota Avalon (XX50): Blind Spot Monitor Sensor

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.

Standard:

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.

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.

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.

Standard:

(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 3373 mm (11.07 ft.) from point A.

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

SST: 09870-60000

SST: 09870-60040

Standard:

NOTICE:

• Set the reflector so that its center is 596 mm (1.95 ft.) above the ground.

  *a	SST (reflector)
  *b	596 mm (1.95 ft.)

• The center of the triangular pyramid is the reference point for the setting position and angle.

  *a	Center Of Triangular Pyramid

• 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:

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.

(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.

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 (+/-5°) by using a jig, and that the sensor is 46 to 54° from the line parallel to the vehicle center line.

(a) Remove the rear bumper assembly.

(b) Attach a jig similar to the one shown in the illustration to the outward facing surface of the blind spot monitor sensor and check that the measurement or angle is within the allowable range to confirm that the blind spot monitor sensor is perpendicular to the floor surface (+/-5°).

Standard:

(c) 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.
