SUSPENSION

DESCRIPTION AND OPERATION

60-13

The air suspension reservoir is fabricated from aluminium and is located under the RH sill of the vehicle. The reservoir 
is secured with four bolts to the underside of the vehicle. The reservoir has an additional bracket on the forward facing 
end which provides the mounting for the valve block. A pressure sensor is screwed into the rear face of the reservoir. 
The sensor is connected to the air suspension ECU and measures the pressure within the reservoir. The pressure 
sensor cannot be replaced. If failure of the sensor occurs, the reservoir, complete with the sensor must be replaced.

The reservoir supplies pressurised air to the four air springs, via the valve block, to enable the air suspension system 
to carry out ride height changes.

Valve Block
The five way air suspension valve block is located under the RH sill of the vehicle, and is mounted forward of the air 
reservoir. The valve block is held in place on the air reservoir support bracket by 3 studs and secured by nuts. The 
studs are bonded into rubber mounts which isolates solenoid operation from the vehicle.

The valve block contains five solenoid operated valves which are controlled by the air suspension ECU. Four of the 
valves, known as corner valves, control the air flow to and from air springs, via the cross-link valves. The fifth valve, 
known as the reservoir valve, controls the air pressure supply from the reservoir to the air springs, via the corner 
valves and cross-link valves and also from the compressor to the reservoir.

Removal of the valve block will require full depressurisation of the air suspension system. The valve block is a non-
serviceable item and should not be disassembled.
