DESCRIPTION
The occupant classification ECU detects the state of the front seat inner belt assembly RH and load sensor when the front passenger side seat is occupied with the ignition switch ON. If the front passenger side seat belt is not fastened, the front passenger side seat belt warning light on the accessory meter assembly blinks. If the seat belt is fastened, the warning light goes off.
