Toyota Sienna Service Manual: Operation check

1. DETECTION RANGE MEASUREMENT AND INDICATOR CHECK

  1.  Turn the IG switch ON.
  2.  Move the shift lever to the R position (when the back sonar and rear clearance sonar is checked).
  3.  With front clearance sonar: Move the shift lever to the N position (when the front clearance sonar is checked).

    NOTICE: Apply the parking brake securely so that the vehicle does not move.

  4.  Turn the clearance sonar main switch ON.
  5.  Move a φ 60 mm (2.36 in.) pole around the sensor to measure the detection range of the sensor.

DETECTION RANGE MEASUREMENT AND INDICATOR CHECK

NOTICE: The measured detection range is for the φ60 mm (2.36 in.) pole. The detection range for walls and other obstacle is different.

  1.  Check the indicator and the buzzer sounding condition when the back sonar sensor detects an obstacle.

2. CHECK INITIAL CHECK FUNCTION

CHECK INITIAL CHECK FUNCTION

  1.  Check the initial check function for the LED and buzzer.

    Turn the ignition switch and clearance main switch ON. The LED are buzzer will operate for about 1 second +- 0.3 seconds, regardless of shift lever position or vehicle speed. The system will then begin normal detection operation.

    If the LED or buzzer is faulty, the relevant LED and buzzer operate as shown in the illustration below.
