Vehicle Height Sensor
WARNING: This page is about a different car, the 2012 Infiniti QX56 and 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle height sensor is installed between rear suspension member (1) and rear lower link (2).
Since arm (A) portion and rod (B) portion are ball joint type, distance between rear suspension member and rear lower link shortens when vehicle height of vehicle rear lowers because of laden or towing conditions, and arm portion changes to the status that is higher in its left side as shown in the figure.
This angle change in arm portion is transmitted to the air levelizer control module according to electric signal.
