1. INSPECT NO. 1 ULTRASONIC SENSOR


E107563E03

  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

  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.



3. INSPECT NO. 3 ULTRASONIC SENSOR


E107562E02

  1. Measure the resistance of the sensor.

    Standard resistance::
    Tester Connection
    [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.
