DESCRIPTION AND OPERATION DESCRIPTION OF COMPONENTS
Electrical control unit - ECU
The ECU is located underneath the front left hand
seat. The ECU maintains the requested vehicle ride
height by adjusting the volume in each air spring. It is
connected to the cable assembly by a 35 way
connector. To ensure safe operation the ECU has
extensive on board diagnostic and safety features.
The ECU must be replaced in case of failure.

DESCRIPTION AND OPERATION HEIGHT SETTINGS
Standard ride height
With the Inhibit switch off (unlatched), at speeds
below 80 km/h (50 mph) the standard ride height
indicator will be illuminated.
Standard vehicle ride height is maintained under all
load conditions. This also maintains headlamp
levelling.
Low ride height
Low ride height is automatically selected when the
vehicle speed exceeds 80 km/h (50 mph) for at least
30 seconds with the inhibit switch off. Low ride height...

DESCRIPTION AND OPERATION High ride height
This position is used to improve approach and
departure angles and when wading. When at standard
ride height, pressing the up switch will select high ride
height provided the road speed is below 56 km/h (35
mph). The high ride height indicator will flash during

DESCRIPTION AND OPERATION SYSTEM OPERATION
Numbers refer to pneumatic circuit diagram
Air is drawn through the inlet filter (1) to the
compressor (2), where it is compressed to 10 ñ 0,5
bar.
Compressed air passes to the air dryer (3) where
moisture is removed as it flows through the dryer
dessicant. The dessicant in the lower portion of the
dryer becomes wet.
Dried air passes through a non-return valve NRV1 to
the reservoir (4).
The 3 non-return valves (6) ensure correct air...

DESCRIPTION AND OPERATION FRONT SUSPENSION
Description
The front suspension design on the New Range Rover
allows maximum wheel travel and axle articulation,
providing good ground clearance without loss of
traction or directional stability.Near constant ride frequency under all load conditions
is achieved by utilizing advancements in suspension
geometry complemented to control and operation of
the air suspension system.
See this section.

DESCRIPTION AND OPERATION Long front radius arms (1) are fitted to the front axle
(7) and provide maximum axle articulation which is
vital for off road performance. The radius arm,
comprising a forged steel link with twin front
mountings using ferrule rubber bushes, is secured to
fabricated mounting brackets welded to the front axle.
Flexible rubber bushes are used on a stem end joint
to secure the rear of the radius arm to a mounting on
the chassis cross member as shown in...

DESCRIPTION AND OPERATION OPERATION
The airbag supplementary restraint system (SRS) is a
safety device which, when used in conjunction with
the seat belt, is designed to protect the driver and
front passenger by operating when the vehicle
receives a frontal impact (in the area shown)
exceeding a certain set speed.
In the event of a frontal impact, when the airbag
diagnostic control unit and one of the airbag crash
sensors senses the impact, the...
