POP UP HOOD SENSOR INSPECTION

PROCEDURE


  1. INSPECT POP UP HOOD SENSOR ASSEMBLY


    1. If there is any evidence of an impact to the front bumper:


      1. Check the front bumper energy absorber and pedestrian detection chamber for deformation and dents.

        OK
        The front bumper energy absorber is not bent or cracked.
        The pedestrian detection chamber is not bent, worn or punctured.

        If the result is not as specified, replace the front bumper energy absorber or pedestrian detection chamber.

      2. Check the airtightness of the pedestrian detection chamber.

    2. If DTC B16A6 was output:


      1. Replace the front bumper energy absorber with a new one.

      2. Visually check for defects with the pedestrian detection chamber removed from the vehicle.

        OK
        The pedestrian detection chamber is not bent, worn or punctured.

        If the result is not as specified, replace the pedestrian detection chamber.

      3. Check the airtightness of the pedestrian detection chamber.

    3. If any of the airbags were deployed:


      1. Replace the pedestrian protection sensor and pedestrian detection chamber with a new one.

  2. AIRTIGHTNESS CHECK


    1. Remove the pop up hood sensor assembly.

    2. A01MSOTC01
      *1 Pedestrian Detection Chamber
      *a Inner Cap Seal

      Remove the cap seal.

      Note


      • If using a screwdriver to remove the cap seal, do not damage the pedestrian detection chamber.

      • If the inner cap seal does not come off with the cap seal, remove it from the pedestrian detection chamber.

    3. A01MTEMN01

      Connect SST to the pedestrian detection chamber.

      SST
      09992-00242

      Note

      Connect the hose securely.

    4. Pump SST to increase the pressure in the pedestrian detection chamber to 20 kPa (0.2 kgf/cm2, 3 psi), wait for 1 minute and check the change in the pressure.

      SST
      09992-00242
      OK
      The reading does not change.

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

      Tech Tips

      When reusing the pedestrian detection chamber, install a new cap seal.
