Title: PARK ASSIST / MONITORING: BLIND SPOT MONITOR SYSTEM: OPERATION CHECK; 2017 MY Sienna [08/2016 - 11/2017]

OPERATION CHECK

1. BLIND SPOT MONITOR BEAM AXIS INSPECTION

(a) Procedure to enter Test Mode

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the blind spot monitor main switch (warning canceling switch assembly) on.

(4) Turn the Techstream on.

(5) Switch the blind spot monitor sensor to Test Mode using the Techstream. Enter the following menus: Body Electrical / Blind Spot Monitor Master or Blind Spot Monitor Slave / Utility / BSM Master Beam Axis Inspection or BSM Slave Beam Axis Inspection.

(6) Finish Test Mode.

2. BLIND SPOT MONITOR BEAM AXIS CONFIRMATION

(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 an object other than the reflector (such as a large metallic object) in or allow people to enter the inspection area (W 9 m (29.53 ft) x L 10 m (32.81 ft) x H 4 m (13.13 ft)) shown in the illustration.
  • Check that DTC C1ABB and DTC C1ABC are not output.

(b) Place the reflector.

(1) Hang a string (with weight) from the center of the vehicle's rear emblem. Mark the vehicle's rear center point on the ground. Repeat for the front of the vehicle (marks A and B).

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

(3) Mark the position on the center line 574 mm (1.88 ft.) behind the rear bumper (mark C).

(4) Prepare 2 pieces of string of 600 mm (1.97 ft.) in length and secure the end of each string at a point 300 mm (11.8 in.) from mark C as shown in the illustration.

(5) Pull the end of each string and mark the position where each string meets on both the left and right side (marks D and E).

(6) Draw a line P so that it passes through marks D and E and is perpendicular to the vehicle center line.

(7) Set the reflector at the position Z shown in the illustration below.

SST: 09870-60000

09870-60010

SST: 09870-60040

NOTICE:

  • Set the reflector so that its center is 566 mm (1.86 ft) above the ground.
  • The center of triangular pyramid is the reference point for the setting position and angle.
  • Set the reflector as shown in the illustration so that its center of triangular pyramid faces the blind spot monitor sensor.
  • Perform the operation as precisely as possible.

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

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the blind spot monitor main switch (warning canceling switch assembly) on.

(4) Turn the Techstream 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.

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

Allowable Range:

Item

Blind Spot Monitor Sensor LH (Slave)

Blind Spot Monitor Sensor RH (Master)

Angle

-3.6 to +3.6°

-3.6 to +3.6°

Distance

2.0 to 3.0 m

(6.57 to 9.85 ft.)

2.0 to 3.0 m

(6.57 to 9.85 ft.)

HINT:

If the results are outside the allowable range, it is possible that the reflector position is incorrect, there is a metallic object near the inspection area or the blind spot monitor sensor installation condition is abnormal, so check the reflector positioning, the inspection area and the blind spot monitor sensor installation condition, and perform the inspection again.

(7) Perform the blind spot monitor beam axis adjustment using the Techstream. 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 the values to the normal value.

3. BLIND SPOT MONITOR 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.

(a) Remove the rear bumper (See page 2017 - 2020 MY Sienna [08/2016 -        ]; EXTERIOR PANELS / TRIM: REAR BUMPER: REMOVAL ).

(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 blind spot monitor sensor is perpendicular to the floor surface or within the allowable range.
