PRECAUTION
- GENERAL PRECAUTION 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.

INITIALIZATION
Note. 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.
- ZERO POINT CALIBRATION Zero point calibration procedure HINT: Make sure that zero point calibration has finished normally, and then perform the sensitivity check. Check that all of the following conditions are met: The vehicle is parked on a level surface. No objects are placed on the front passenger seat. The front passenger seat belt buckle switch is off. Adjust the seat position according to the table below. Adjustment Item Position Slide Direction Rearmost position Reclining Angle Upright position Headrest Height Lowest position Lifter Height Lowest position Turn the power switch off. Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical / Occupant Detection / Utility / Zero Point Calibration. 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 does not complete, replace the front seat assembly RH. OK "Zero Point Calibration is complete." is displayed.
- SENSITIVITY CHECK Sensitivity check procedure Turn the power switch off. Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical / Occupant Detection / Utility / Sensitivity Check. Perform the sensitivity check by following the prompts on the Techstream screen. HINT: Refer to the Techstream operator's manual for further details. Confirm that the initial sensor reading is within the specified range. Standard -3.2 to 3.2 kg (-7.0 to 7.0 lb) Place a 30 kg (66.1 lb) weight (e.g. a 30 kg (66.1 lb) of lead mass) onto the front passenger seat. Confirm that sensitivity is within the specified range. Standard 27 to 33 kg (59.5 to 72.8 lb) HINT: When performing the 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 assembly RH.
FAIL-SAFE CHART
- FAIL SAFE FUNCTION The following chart shows the status of the controls when the system is normal and malfunctioning. The passenger airbag ON/OFF indicator ("ON" and "OFF") comes on for approximately 4 seconds, then goes off for approximately 2 seconds. Approximately 6 seconds after the power switch was turned on (IG), the passenger airbag ON/OFF indicator will indicate ON or OFF depending on the conditions listed below.
