1. INSPECT DECELERATION SENSOR

4WD:

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

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

1. Connect the voltmeter's positive (+) lead to the negative (-) lead of the batteries, and the positive (-) lead to terminal 1 (GL1). Apply approximately 4.5 V.

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

1. 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. 2.5 V
     1 (GL1) - Battery's negative (-) lead | Tilted forward | Approx. 0.5 to 2.5 V
     1 (GL1) - Battery's negative (-) lead | Tilted rearward | Approx. 2.5 to 4.5 V

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