Check RAS Static/Dynamic Characteristics

Perform CONSULT-III "ACTIVE TEST", and then check the actuator stroke when turning the steering wheel clockwise or counterclockwise by 180° or more.

Neutral position (A) 

Actuator stroke (B) : 2.8 - 3.0 mm (0.110 - 0.118 in)

OK: GO TO 2.

NG: GO TO  3.

Perform CONSULT-III "ACTIVE TEST". When turning the steering wheel in neutral position (A), the rear wheel turns clockwise/counterclockwise periodically. At that time, check actuator stroke (B).

Actuator stroke (B) : 2.3 - 2.5 mm (0.091 - 0.098 in)
