POP UP HOOD SENSOR INSPECTION

PROCEDURE


  1. INSPECT PEDESTRIAN DETECTION CHAMBER WITH PEDESTRIAN PROTECTION SENSOR


    1. If B16A6 is output, any deformation caused by a hit-and-run accident, any signs of damage from hitting something lightly when parking, any airbags deployed or any defects as mentioned below, replace the front bumper energy absorber or No. 2 front bumper mounting bracket with a new one.


      Standard
      Front bumper energy absorber has bends or cracks
      No. 2 front bumper mounting bracket has bends, cracks, whitening or impact marks

      1. Perform an air tightness check on the pedestrian detection chamber assembly.

      *b 7 mm (0.276 in.)
      *c Use
      *d Not Use

      Connect the attachment to SST.

      Note

      Using attachment shown in the illustration.

    3. Using the supplied attachment, connect the SST to the breathing hole on the other side of the sensor.

      Note

      Check that the securely connect the SST.

    4. Use your hand to cover one of the breathing holes on the pedestrian protection sensor.

    5. Increase the pressure until the needle on the vacuum pump reaches 20 kPa (150 mmHg).

      Tech Tips

      Approximately 2 pumps are needed to increase the pressure to 20 kPa (150 mmHg).

    6. Wait 10 Seconds, and check that the needle has not moved.

      Tech Tips

      If the needle changes, replace the pedestrian detection chamber assembly with a new one.
