DESCRIPTION

When the front passenger seat belt is not fastened with the engine switch on (IG) and the front passenger seat occupied, the front passenger seat belt warning light on the air conditioning control assembly blinks. The occupant detection sensor detects if the front passenger seat is occupied and sends signals to the combination meter assembly. The front seat inner belt assembly detects the front passenger seat belt condition and sends signals to the combination meter assembly. After receiving the signals from the occupant detection sensor and front seat inner belt assembly, the combination meter assembly sends signals to the air conditioning control assembly to request the front passenger seat belt warning light to blink or go off.
