Perform zero point calibration and sensitivity check if any of the following conditions occur: 

• The occupant detection ECU is replaced.
• Accessories (seatback tray, seat cover, etc.) are installed.
• The front passenger seat is removed from the vehicle.
• One of the bolts that is used to install the front passenger seat is removed and reinstalled.
• The passenger airbag ON/OFF indicator ("ON") comes on when the front passenger seat is not occupied.
• An occupant classification sensor collision detection DTC is output due to an accident or a collision.

1. ZERO POINT CALIBRATION AND SENSITIVITY CHECK 
   1. Zero point calibration and sensitivity check procedure
      1. Check that both of the following conditions are met:
         • The vehicle is parked on a level surface.
         • No objects are placed on the front passenger seat.
      2. Adjust the seat position according to the table below.

         Adjustment Item	Position
         Slide Direction	Rearmost position
         Headrest Height	Lowest position
         Front Tilt Height	Lowest position
         Seat Lifter Height	Lowest position
         Recline Angle	Upright position

      3. Turn the engine switch off.
      4. Connect the Techstream to the DLC3.
      5. Turn the engine switch on (IG).
      6. Turn the Techstream on.
      7. Enter the following menus: Body Electrical / Occupant Detection / Utility / Zero Point Calibration & Sensitivity Check.

         Body Electrical > Occupant Detection > Utility 

         Tester Display
         Zero Point Calibration & Sensitivity Check

      8. Perform zero point calibration and sensitivity check by following the prompts on the Techstream screen.

         OK

         "Zero Point Calibration is complete." and "Sensitivity Check is complete." are displayed.

         HINT: 

         • Refer to the Techstream operator's Service Information for further details.
         • If zero point calibration does not complete, replace the front seat adjuster assembly RH.
         • When performing sensitivity check, use a solid metal weight (the check result may not appear properly if a liquid weight is used).
         • When performing sensitivity check, place the weight on the seat cushion so that it contacts the seatback.
         • If sensitivity deviates from the specified range, retighten the bolts of the front passenger seat without deforming the seat rail. After performing this procedure, if sensitivity is not within the specified range, replace the front seat adjuster assembly RH.
