5th Bow 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.
5th bow status sensor is installed to 5th bow drive cylinder and is a hall sensor.
When 5th bow drive bow 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 5th bow by this amount of current.
