Ride Height Sensor: Description and Operation

HEIGHT CONTROL SENSOR
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 indication the shaft rotation angle.

HEIGHT CONTROL SWITCH
CIRCUIT DESCRIPTION
This is the height control system main switch. When the height control switch is pushed, the height control OFF indicator light lights up and height control goes off.
The "OFF" condition of the height control will not be cancelled until the height control switch is pushed again or the vehicle is driven.

HEIGHT SELECT SWITCH
This circuit sending the signal to ECU in order to adjust the height to the aimed height selected by the height select switch.
