Check RAS Static/Dynamic Characteristics

Perform CONSULT-II "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 or NG 

OK: GO TO 2.

NG: GO TO  3.

Perform CONSULT-II "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) 

OK or NG 

OK: RAS static/dynamic characteristics inspection is completed.

NG: GO TO 3.

Check RAS motor itself separated from other parts. Refer to "RAS MOTOR ".

OK or NG 

OK: GO TO 4.

NG: RAS motor malfunction. Check the stroke again after replacing.

Check rear wheel steering angle sensor separated from other parts. Refer to "REAR WHEEL STEERING ANGLE SENSOR ".

OK or NG 

OK: GO TO 5.

NG: Rear wheel steering angle sensor malfunction. Check the stroke again after replacing.

Replace RAS control unit. Check the symptom of malfunction again.

Is the malfunction corrected? 

Yes: RAS control unit malfunction

NO: GO TO 6.

Replace RAS actuator assembly. Check the symptom of malfunction again.

Is the malfunction corrected? 

Yes: RAS actuator malfunction

No: Check rear suspension components. Refer to "COMPONENTS ".
