Deceleration Sensor (W/O Vsc) -- Inspection



1. INSPECT DECELERATION SENSOR

  1. Connect 3 dry cell batteries of 1.5 V in series (approximately 4.5 V in total).

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

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

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

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

    Standard Voltage:
    Tester Connection
    		Condition
    		Specified Condition
    1 (GL1) - Battery negative (-) lead
    		Sensor is horizontal
    		Approx. 2.25 V
    1 (GL1) - Battery negative (-) lead
    		Sensor is tilted forward
    		Approx. 0.45 to 2.25 V
    1 (GL1) - Battery negative (-) lead
    		Sensor is tilted rearward
    		Approx. 2.25 to 4.05 V

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


2. CHECK DECELERATION SENSOR

  1. Check the deceleration sensor.
    Under any of the following conditions, replace the sensor with a new one.

    1. The surface of the sensor is cracked, dented or chipped.
    2. The connector is scratched, cracked or damaged.
    3. The sensor has been dropped.
