3. CHECK (2): REAR WHEEL STEERING ANGLE SENSOR POWER SUPPLY AND GROUND CIRCUIT
1. Turn ignition switch OFF, disconnect rear wheel steering angle sensor harness connector B104 and RAS
control unit harness connector B127.
2. Check continuity each harness connector of rear wheel steering
angle sensor harness connector B 104 and RAS control unit
harness connector B127.
OK or NG
OK >> RAS control unit malfunction. Replace RAS control unit.
NG >> Harness between rear wheel steering angle sensor and RAS control unit open or shorted. Repair
or replace harness.
4. CHECK REAR WHEEL STEERING ANGLE SENSOR OUTPUT SIGNAL
1. Connect rear wheel steering angle sensor harness connector B104.
2. Check voltage RAS control unit harness connector B127 when
starting the engine and turning the steering wheel from neutral
position clockwise/counterclockwise by 180
.
CAUTION:
There is approximately 1 V or more difference between main output and sub output at straight-ahead position, inspection
results are “NG”.
OK or NG
OK >> RAS control unit malfunction. Replace RAS control unit.
NG >> GO TO 5.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
Check RAS Static/Dynamic CharacteristicsNGS000F3
1. CHECK (1): RAS ACTUATOR STROKE
Perform CONSULT-II “ACTIVE TEST”, and then check the actuator
stroke when turning the steering wheel clockwise or counterclock-
wise by 180
or more.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK (2): RAS ACTUATOR STROKE
Perform CONSULT-II “ACTIVE TEST“. When turning the steering
wheel in neutral position (A), the rear wheel turns clockwise/counter-
clockwise periodically. At that time, check actuator stroke (B).
OK or NG
OK >> RAS static/dynamic characteristics inspection is com-
pleted.
NG >> GO TO 3.
3. CHECK RAS MOTOR
Check RAS motor itself separated from other parts. Refer to STC-49, "
RAS MOTOR" .
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 STC-49, "
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.
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 RSU-7, "
Components" . Neutral position (A)
Actuator stroke (B) : 2.8 - 3.0 mm (0.110 - 0.118 in)
