ACTIVE-ELECTRONIC CONTROL SUSPENSION
Air compressor

Exhaust solenoid valve
SERVICE POINTS OF REMOVAL
2. REMOVAL OF AIR TUBE
Caution
1. In order to prevent dust, dirt and other foreign
material from getting into the air tube and air
compressor openings, cover these opening with
vinyl tape or similar material.
2. Be careful not to bend the air tubes.
INSPECTION
(1) Using special tool (adaptor
connect the air tube on the
gauge side of the special tool to the air compressor.
(2) Apply battery voltage
between terminals (1) and (2)
compressor.
(3) Check whether the relief pressure of the air compressor is
the standard value.
Standard value:
(142-185 psi)
NOTE
Because of pulsation caused by the opening and closing
of the exhaust solenoid valve combined with the relief
valve, the gauge’s indicator
show a reading which
fluctuates within a range of
(29-43 psi). Use
the mid-point of this fluctuation to make the gauge reading.
(4) Stop the air compressor and, with the pressure held, apply
battery voltage
between air compressor terminals (3)
and (4). At this time, check to be sure that the exhaust
solenoid valve makes a “click” sound and the pressure is
gradually decreasing.
(5) If air compressor relief pressure is not within the standard
value, or if there is a malfunction of the exhaust solenoid
valve, replace the air compressor.
Caution
When the air compressor is replaced, first check to be
sure that there is no air leakage at air tube joints, no
poor contacts of wiring, and that the
switch is
not in operation.
SERVICE POINTS OF INSTALLATION
2. INSTALLATION OF AIR TUBE
(1) First insert the air tube at the lower part of the dryer
until resistance is felt, and then press the tube further
inward to the paint mark on the air tube.
Caution
Air leakage may occur if the air tube connection is
not complete and secure.
(2) Connect air tubes correctly to the air compressor.
Apply a soap-and-water solution to the air tube
connections to check to be sure that there is no air
leakage.
