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

PROCEDURE

1. INSPECT DECELERATION SENSOR

   
   

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

      *a	Front
      *b	Forward
      *c	Rearward

      Check the output voltage of terminal 1 (GL1) when the sensor is tilted forward and rearward.

      Standard Voltage
      Tester Connection Condition Specified Condition 1 (GL1) - Battery negative (-) lead Sensor is horizontal Approx. 2.25 V 1 (GL1) - Battery negative (-) lead Sensor is tilted forward Approx. 0.45 to 2.25 V 1 (GL1) - Battery negative (-) lead Sensor is tilted rearward Approx. 2.25 to 4.05 V

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

      Tech Tips

      
      

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

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

2. 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.

      • The connector is scratched, cracked or damaged.

      • The sensor has been dropped.
