LUCAS EAS (P38 NRR)

The EAS (Electronic Air Suspension) system, designed and manufactured by Dunlop, as fitted to the new shape Range Rover. It is a slightly modified and improved version of the Classic Air suspension system. It has a fault memory which can be read and cleared, it also gives a range of dynamic information values, which are; for each of the four vehicle corners, height sensor feedback values, current target heights, and current valve state, which includes both exhaust and inlet valves, compressor state, switch states for thermal, pressure, inhibit, raise and lower, battery voltage, road speed (KPH/MPH), Engine RPM, foot and hand brake switch states, door ajar inputs and the current ride state. It allows the driving of a selection of outputs which not only enables testing of all of the systems valves, but allows deflation and depressurization of the entire system which due to the high pressures involved is crucial to carry out any repair work at all. Access is obtained to all stored height values for all ride heights allowing full calibration of the sensors which govern vehicle height. This New Range Rover version also includes electronic lock modes which are essential not only for post/pre transportation preparation but to allow certain component replacement to be performed. The Classic Range Rover version of this system had these functions supplied only as external supply disconnection switches.
