SUPPLEMENTAL RESTRAINT SYSTEM: OCCUPANT CLASSIFICATION SYSTEM: INITIALIZATION

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 the 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 intelligent tester to the DLC3.
(3) Turn the power switch on (IG).
(4) Perform the zero point calibration by following the prompts on the tester screen.





HINT: Refer to the intelligent tester operator's manual for further details.

OK:
"COMPLETE" is displayed.
(5) Perform the sensitivity check by following the prompts on the tester screen.
(6) Confirm that the beginning sensor reading within standard value.
Standard value:
-3.2 to 3.2 kg (-7 to 7 lb)
(7) Place a 30 kg (66.14 lb) weight (eg. a 30 kg (66.14 lb) of lead mass) onto the front passenger seat.
(8) Confirm that the sensitivity is within the standard value.





Standard value:
27 to 33 kg (59.52 to 72.75 lb)

HINT:
- When performing the sensitivity check, use a solid metal weight (the check result may not appear properly if the weight made from liquid is used).
- When the sensitivity deviates from the standard value, 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 value, replace the front seat assembly RH.
- When zero point calibration has not finished normally, replace the front seat assembly RH.
