    INSPECT REAR ACCELERATION SENSOR


    1. A01DOSFE07

      Connect 3 dry batteries of 1.5 V in series.

    2. 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).

    3. 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

      Tip:

      When the rear acceleration sensor is tilted, it may output a different value.

      Note:

      • Do not apply higher than 6 V.

      • Do not drop the rear acceleration sensor. If it is dropped, replace it with a new one.

      • Never place the rear acceleration sensor upside down.

      If the result is not as specified, replace the rear acceleration sensor.
