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)

3. If the actuator does not operate, disconnect the ac-
tuator connector and check for a few ohms resis-
tance between the terminals.
