Checking Condition
Note:
Turn the ignition switch OFF to reset the con-
trol unit before each test.
Condition A
1. Turn the ignition switch ON.
2. Set steering wheel in the straight-ahead position,
and check the output pattern.
86U15X-154
Condition B
1. Turn the ignition switch ON.
2. Turn the steering wheel right and left, and check
the output pattern.

AUTO ADJUSTING SUSPENSION I- AUTO—i SOFT NORMAL SPORT
Condition C
1. Turn the ignition switch ON.
2. Change the AAS switch from NORMAL to SPORT
or from SPORT to NORMAL, and check the out-
put pattern.
86U15X-156
Condition D
1. Operate the vehicle on a chassis roller.
2. Check the output pattern at above 15 km/h (9.3
mph).
Caution
a) Block the rear wheels.
b) In vehicle equipped with ABS, ABS warn-
ing light may come on, which is not a fail-
ure. The light goes off by turning ignition
switch OFF and again ON.

Actuator
Inspection
1. Turn the ignition switch ON.
2. Alternately switch ON the "NORMAL" and
"SPORT" switches. Check whether the shaft of the
actuator installed on the front and rear damper
operates. (Visual inspection)

tuator connector and check for a few ohms resis-
tance between the terminals.
