1. INSPECT DECELERATION SENSOR


C108887E03
4WD:

  1. Connect 3 dry cell batteries of 1.5 V in series.

  1. Connect the batteries' positive (+) lead to terminal 3 (VGS) and the negative (-) lead to terminal 2 (GGND).

  1. Connect the voltmeter's positive (+) lead to the negative (-) lead of the batteries, and the positive (-) lead to terminal 1 (GL1). Apply approximately 4.5 V.

    HINT:
    Do not apply voltage of 6 V or more to terminals 3 (VGS) and 2 (GGND).

  1. Check the output voltage of terminal 1 (GL1) when the sensor is tilted forward and rearward.

    Standard Voltage:
    Tester Connection
    		Sensor Position
    		Specified Condition
    1 (GL1) - Battery's negative (-) lead
    		Horizontal
    		Approx. 2.5 V
    1 (GL1) - Battery's negative (-) lead
    		Tilted forward
    		Approx. 0.5 to 2.5 V
    1 (GL1) - Battery's negative (-) lead
    		Tilted rearward
    		Approx. 2.5 to 4.5 V

    HINT:
    1. If voltage drops, the sensor should be replaced with a new one.
    2. When replacing the sensor, it should not be placed upside down.
    3. If the result is not as specified, replace the deceleration sensor.
