B1661 TOYOTA Description
The Curtain Shield Airbag Cutoff Switch is a mechanism that operates both the right and left sides of the Curtain Shield Airbag and the Front Seat Outer Belt when the Center Airbag Sensor detects a roll-over. The Roll Sensing Curtain Airbag (RSCA) OFF indicator is installed in the Combination Meter. If the Curtain Shield Airbag Cutoff Switch is operated, the indicator comes on to inform the drive that the roll-over detection system is not working. The initial setting of the roll-over detection system is on. It automatically operates every time the engine switch is turned on (IG).
