Roof Status Sensor
WARNING: This page is about a different car, the 2011 Nissan 370Z. However, it is still accessible from the selected car via links, so may be relevant.
Roof status sensor is installed to roof drive cylinder and is a hall sensor.
When roof drive cylinder is extended or retracted, the position of piston and sensor in the cylinder changes and the magnetic field around the sensor changes.
By this operation, sensor output current changes. Soft top control unit judges the state of soft top by this amount of current.
