SUPPLEMENTAL RESTRAINT SYSTEMS: OCCUPANT CLASSIFICATION SYSTEM: INITIALIZATION

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 detection ECU is replaced.
* Accessories (seatback tray and seat cover, etc.) are installed.
* The front passenger seat is removed from the vehicle.
* One of the bolts that install the front passenger seat is removed.
* The passenger airbag ON/OFF indicator ("OFF") comes on when the front passenger seat is not occupied.
* The vehicle is brought to the workshop for repair due to an accident or a collision.

1. ZERO POINT CALIBRATION AND SENSITIVITY CHECK

(a) Zero point calibration and sensitivity check procedure

HINT
Make sure that zero point calibration has finished normally, and then perform the sensitivity check.

(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.





(3) Turn the power switch off.

(4) Connect the Techstream to the DLC3.

(5) Turn the power switch on (IG).

(6) Turn the Techstream on.

(7) Enter the following menus: Body Electrical / Occupant Detection / Utility / 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 manual for further details.
* If zero point calibration does not complete, replace the front seat frame with 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).
* 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 frame with adjuster assembly RH.
