Ultrasonic Sensor -- Inspection



1. INSPECT NO. 1 ULTRASONIC SENSOR


Lexus Gs430, Gs300. Uzs190 Grs190.Park Assist Monitoring.Clearance Sonar System.Ultrasonic Sensor  Inspection
  1. Measure the resistance of the sensor.

    Standard resistance:
    Tester Connection
    Condition
    Specified Condition
    1 (E) - 2 (S)
    Always
    900 +- 300 kΩ
    NOTICE:
    Set the tester to the 100 kΩ range before performing the measurement.


2. INSPECT NO. 2 ULTRASONIC SENSOR

    [Tester (+) - Tester (-)]
    Condition
    Specified Condition
    3 (S) - 2 (E)
    Always
    40 +- 10 kΩ
    2 (E) - 3 (S)
    Always
    40 +- 10 kΩ
    1 (T) - 2 (E) *
    Always
    330 +- 100 kΩ
    2 (E) - 1 (T) *
    Always
    1 MΩ or higher
    NOTICE:
    1. Set the tester to the 100 kΩ range before performing the measurement.
    2. *: Measurement values may vary depending on the tester used. If results seem inaccurate, reverse the polarity (+-) and measure again.
