Adult Judgment
When the judgment value is higher than criteria value B, the occupant classification ECU judges that the
seat is being occupied by an adult.
If the power switch is turned IG-ON in this state, the system performs an initial check and illuminates
the AIRBAG ON indicator light, indicating that the front passenger airbag and the front passenger side
airbag are active.
After the occupant classification ECU judges that the occupant is as adult, and if the judgment value is
determined as criteria value B or less according to occupant load movement, the ECU continues adult
judgment for approximately ten seconds before switching the child judgment.
