Check RAS Static/Dynamic Characteristics

TROUBLE DIAGNOSIS


Check RAS Static/Dynamic Characteristics

1.CHECK (1): RAS ACTUATOR STROKE





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 or NG
OK - GO TO 2.
NG - GO TO 3.
2.CHECK (2): RAS ACTUATOR STROKE





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)

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. Refer to Component Inspection.
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. Refer to Component Inspection.
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 Component.
