SYSTEM DESCRIPTION
1. GENERAL
This system uses pneumatic cylinders instead of the coil springs that are used in a conventional rear
suspension. The suspension control ECU analyzes the information based on the switches, sensors,
and input signals, operates the compressor assy, and uses the solenoid valves to control the vehicle
height.
The suspension control ECU detects, via the height control sensor, the changes in the rear vehicle
height that results from the number of occupants or the amount of the load. Then, the suspension con-
trol ECU controls the height control solenoid valves and the compressor assy in order to automatically
adjust the rear vehicle height to a constant (normal) vehicle height.
Furthermore, three vehicle heights can be selected by operating the height control switch: HI, NOR-
MAL, and LO. The HI vehicle height ensures the vehicle's drive±through performance on rough roads.
The LO vehicle height facilitates the entry and exit of the occupants and the loading and unloading
of cargo. The NORMAL vehicle height helps realize excellent controllability and riding comfort during
normal driving.

7. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
8. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
field coil end and field frame.
If there is no continuity, repair or replace the field frame.
9. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, measure the resistance between shunt
coil terminals (A) and (B).
Resistance: 1.5 to 1.9 W at 20 °C (68 °F)
If the resistance is not as specified, replace the field frame.
10. INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length: 15.0 mm (0.591 in. )
Minimum length: 9.0 mm (0.354 in. )
If the length is less than minimum, replace the brush holder and
field frame.
11. INSPECT BRUSH SPRING LOAD
Using a pull scale, measure the spring load by pulling the spring
from the brush until they are separated.
Standard spring installed load: 21.5 to 27.5 N ( 2.2 to
2.8 kgf, 4.8 to 6.2 lbf )
Minimum installed load: 12.7 N (1.3 kgf, 2.9 lbf )
If the installed load is less than minimum, replace the brush
springs.

REMOVAL
1. REMOVE FRONT WHEEL
2. DISCONNECT SHOCK ABSORBER FROM LOWER
SUSPENSION ARM
(a) Remove the shock absorber lower side set nut and wash-
er.
NOTICE:
Do not remove the bolt.
(b) Pry down the lower suspension arm to remove the bolt
and disconnect the shock absorber.
3. REMOVE SHOCK ABSORBER WITH COIL SPRING
Remove the 3 nuts and shock absorber with the coil spring.

DISASSEMBLY
REMOVE SUSPENSION SUPPORT AND COIL SPRING
(a) Using a spring compressor, compress the coil spring.
NOTICE:

Use a spring compressor with which compressive
force of 12,740 N (1,300 kgf, 2,860 lbf) or more can be
applied.

Make sure that the suspension support is free from
the coil spring.

Do not compress the coil spring more than neces-
sary.

Do not place yourself over the top of the shock ab-
sorber.
(b) Remove the suspension support center nut.
(c) Remove the 2 retainers, cushion, suspension support
and coil spring.
