DECELERATION SENSOR INSPECTION

PROCEDURE

  1. CHECK DECELERATION SENSOR

    1. Check the deceleration sensor.

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

      • The surface of the sensor is cracked, dented, or chipped off.

      • The connector or wire harness is scratched, cracked, or damaged.

      • The sensor has been dropped.

  2. INSPECT DECELERATION SENSOR

      Forward

      *c

      Rearward

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

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

      Note:

      Do not apply 6 V or higher to terminals 1 (VGS) and 2 (GGND).

    3. Connect the voltmeter's positive (+) lead to the negative (-) lead of the batteries, and the negative (-) lead to terminal 3 (GL1).

    4. Check the output voltage of terminal 3 (GL1) when the sensor is tilted forward and rearward.

      Sensor Position

      Specified Condition

      3 (GL1) - Battery's negative (-) lead

      Horizontal

      Approx. 2.25 V

      3 (GL1) - Battery's negative (-) lead

      Tilted forward

      Approx. 0.45 to 2.25 V

      3 (GL1) - Battery's negative (-) lead

      Tilted rearward

      Approx. 2.25 to 4.05 V

      If the result is not as specified, replace the deceleration sensor.

      Tip:

      • If voltage drops, the sensor should be replaced with a new one.

      • When replacing the sensor, it should not be placed upside down.
