2007 INFINITI M35 clock

STC-42
[RAS]
TROUBLE DIAGNOSIS
Revision: 2007 April2007 M35/M45
4. CHECK REAR WHEEL STEERING ANGLE SENSOR OUTPUT SIGNAL
1. Connect rear wheel steering angle sensor harness connector B465.
2. Check voltage RAS control unit harness connector B476 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.
5. CHECK REAR WHEEL STEERING ANGLE SENSOR OUTPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF, disconnect rear wheel steering angle sensor harness connector B465 and RAS
control unit harness connector B476.
2. Check continuity between each harness connector of rear wheel
steering angle sensor harness connector B465 (A) and RAS
control unit harness connector B476 (B).
OK or NG
OK >> Rear wheel steering angle sensor malfunction. Replace
rear wheel steering angle sensor.
NG >> Harness between rear wheel steering angle sensor and
RAS control unit open or shorted. Repair or replace harness.

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-50, "
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-50, "
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)
SGIA1240E
Actuator stroke (B) : 2.3 - 2.5 mm (0.091 - 0.098 in)
