DECELERATION SENSOR (for 4WD and Pre-Runner without VSC) ON-VEHICLE INSPECTION


  1. INSPECT DECELERATION SENSOR

    A01DXBEE03

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

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

      Note

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

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

    4. 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. 2.25 V
      1 (GL1) - Battery's negative (-) lead Tilted forward Approx. 0.45 to 2.25 V
      1 (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.

      Tech Tips


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

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