Height Control Switch/Sensor (Level Control)

CIRCUIT DESCRIPTION
Inside each sensor, a brush integrated with the control sensor rotor shaft moves above the resister, proving linear output. The resistance value between the brush and resistor terminal changes in proportion to the shaft rotation angle, so the fixed voltage applied to the resistor by the ECU is modified by the sensor and output to the ECU as a voltage indicates the shaft rotation angle.

Fail safe function:
If a trouble occurs in the height control sensor circuit, the height control is prohibited after the ECU has adjusted the vehicle height to the standard (fluid pressure correspond to the standard height).
