Description

Rear Right-Hand Ride Height Sensor within the air suspension and headlamp levelling systems.

This rotary position sensor mounts to the right-hand rear suspension arm and monitors suspension travel by tracking the relative arm position. The signal is fed to the Electronic Air Suspension (EAS) ECU to maintain correct ride height, and simultaneously to the automatic headlamp levelling control to adjust the Xenon beam angle in response to changes in vehicle loading. Both functions depend on an accurate, calibrated signal from this sensor.

Applied to vehicles fitted with Xenon headlamps, where the rear ride height sensors serve a dual role in suspension and lighting control.
