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

  1. Connect the positive (+) end of the batteries to terminal 3 (SGV) of the acceleration sensor and the negative (-) end of the batteries to terminal 2 (SGND). Then measure the voltage between terminal 1 (SGRR) and terminal 2 (SGND).

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
    		Sensor Condition
    		Specified Condition
    1 (SGRR) - 2 (SGND)
    		Sensor stationary
    		Approx. 2.0 to 2.5 V
    Sensor tilted
    		Changes between approx. 0.9 and 2.3 V

    HINT:
    When the rear acceleration sensor is tilted, it may output a different value.
    NOTICE:
    1. Do not apply higher than 6 V.
    2. Do not drop the rear acceleration sensor. If it is dropped, replace it with a new one.
    3. Never place the rear acceleration sensor upside down.
    If the result is not as specified, replace the rear acceleration sensor.
