CHECKING FOR STRUT ASSEMBLY AIR LEAKAGE
(1) Disconnect the flow-control solenoid valve’s air tube (connected to the high-pressure side of the reservoir tank)
shown in the illustration, and then take off the join
t
assembly.
NOTE
This air tube is connected, via the reservoir tank and the dryer, to the compressor assembly.
(2) Install the removed joint assembly to the special tool (adaptor set) and then connect to the disconnected air
tube.

AND REASSEMBLY (3) In order to prevent double-folding of the air spring di-
aphragm after reconnection of the air tube, the vehicle-
height switch should be pressed (with the vehicle lifted)
two seconds or more so as to supply air to the air spring.
NOTE
By using the switch as described above, air should be
introduced to the rear air springs and front air springs, in
that sequence, for five seconds each.

1. CONNECTION OF AIR TUBE (1) After applying a coating of rubber grease to the O-ring, install the O-ring, bush and joint at the shock absorber
assembly side.
Caution
1.The O-ring might be damaged if it is installed at
the air tube side and then the insertion is made.
2. The bush must be installed so that the projec-
tion part is facing in the direction indicated in
the illustration.
(2) First insert the air tube until resistance is felt, and then push in the tube until the painted place on the air tube.
Caution
Air leakage may occur if the air tube connection is
not complete and secure.
