Valve Block

The 5-way air suspension valve block is located under the right sill of the vehicle, and is mounted forward of the air reservoir. See Figure. 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 5 solenoid operated valves which are controlled by the air suspension ECU. The 4 corner valves control the air flow to and from air springs, via the cross-link valves. 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 depressurization of the air suspension system. The valve block is a non-serviceable item and should not be disassembled.
