SUPPLEMENTAL RESTRAINT SYSTEM: OCCUPANT CLASSIFICATION SYSTEM: INITIALIZATION

1. ZERO POINT CALIBRATION
NOTICE: Make sure that the front passenger seat is not occupied before performing the operation.
HINT:
Perform zero point calibration and sensitivity check if any of the following conditions occur:
- The occupant classification ECU is replaced.
- Accessories (seatback tray and seat cover, etc.) are installed.
- The front passenger seat is removed from the vehicle.
- The passenger airbag ON/OFF indicator ("OFF") comes on when the front passenger seat is not occupied.
- The vehicle is brought to a workshop for repair due to an accident or a collision.

(a) Zero point calibration and sensitivity check procedures.
HINT: Make sure that zero point calibration has finished normally, and then perform the sensitivity check.
(1) Adjust the seat position according to the table below.





(2) Connect the Techstream to the DLC3.
(3) Turn the ignition switch to the ON position and turn the Techstream ON.
(4) Enter the following menus: Body Electrical / Occupant Detection / Utility / Zero Point Calibration.
(5) Perform zero point calibration by following the prompts on the Techstream screen.
HINT:
- Refer to the Techstream operator's manual for further details.
- If zero point calibration has not finished normally, replace the front seat assembly RH.

OK:
"Zero Point calibration is complete." is displayed.
(6) Enter the following menus: Body Electrical / Occupant Detection / Utility / Sensitivity Check.
(7) Perform sensitivity check by following the prompts on the Techstream screen.
(8) Confirm that the beginning sensor reading is within the standard range.
Standard values:
-3.2 to 3.2 kg (-7 to 7 lb)
(9) Place a 30 kg (66.14 lb) weight (eg. a 30 kg (66.14 lb) of lead mass) onto the front passenger seat.
(10) Confirm that the sensitivity is within the standard range.
Standard values:
27 to 33 kg (59.52 to 72.75 lb)
HINT:
- When performing sensitivity check, use a solid metal weight (the check result may not appear properly if a liquid weight is used).
- If the sensitivity deviates from the standard range, retighten the bolts of the front passenger seat without deforming the seat rail. After performing this procedure, if the sensitivity is not within the standard range, replace the front seat assembly RH.
