Check RAS Static/Dynamic Characteristics

Check RAS Static/Dynamic Characteristics

Components:

1. CHECK (1): RAS ACTUATOR STROKE

Perform CONSULT-II "ACTIVE TEST", and then check the actuator stroke when turning the steering wheel clockwise or counterclockwise by 180° or more. Active Test
Neutral position (A)
Actuator stroke (B): 2.8 - 3.0 mm (0.110 - 0.118 inch)
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK (2): RAS ACTUATOR STROKE

Perform CONSULT-II "ACTIVE TEST". Active Test
When turning the steering wheel by approximately 30° 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 inch)
OK or NG
OK >> RAS static/dynamic characteristics inspection is completed.
NG >> GO TO 3.
3. CHECK RAS MOTOR
Check RAS motor itself separated from other parts.
OK or NG
OK >> GO TO 4.
NG >> RAS motor malfunction. Check the stroke again after replacing.
4. CHECK REAR WHEEL STEERING ANGLE SENSOR
Check rear wheel steering angle sensor separated from other parts.
OK or NG
OK >> GO TO 5.
NG >> Rear wheel steering angle sensor malfunction. Check the stroke again after replacing.
5. CHECK RAS CONTROL UNIT
Replace RAS control unit. Check the symptom of malfunction again.
Is the malfunction corrected?
YES >> RAS control unit malfunction
NO >> GO TO 6.
6. REPLACE RAS ACTUATOR ASSEMBLY
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".
