- GO TO 2.

2. PERFORM DTC CONFIRMATION

With CONSULT
1.Turn the ignition switch OFF to ON.
2.Perform self-diagnosis for "ALL MODE AWD/4WD".
Is DTC "P183A" detected?
YES- Proceed to .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK ELECTRIC CONTROLLED COUPLING (RIGHT) TEMPERATURE SENSOR POWER SUPPLY

1.Turn the ignition switch OFF.
2.Disconnect rear final drive assembly harness connector.
3.Turn the ignition switch ON.

CAUTION:
Never start the engine.
4.Check the voltage between rear final drive assembly harness connector terminals.





Is the inspection result normal?
YES- GO TO 3.
NO- GO TO 2.

2. CHECK ELECTRIC CONTROLLED COUPLING (RIGHT) TEMPERATURE SENSOR CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect AWD control module harness connector.
3.Check the continuity between AWD control module harness connector and rear final drive assembly harness connector.





4.Check the continuity between rear final drive assembly harness connector and ground.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace error-detected parts.

3. CHECK ELECTRIC CONTROLLED COUPLING (RIGHT) TEMPERATURE SENSOR

Check the electric controlled coupling (right) temperature sensor. .
Is the inspection result normal?
YES- GO TO 4.
NO- Electric controlled coupling (right) temperature sensor is malfunctioning. Replace electric controlled coupling (right). Removal And Installation.

4. CHECK TERMINALS AND HARNESS CONNECTORS

Check the pin terminals for damage or loose connection with each harness connector.
Is the inspection result normal?
YES- Replace AWD control module. Removal And Installation.
NO- Repair or replace error-detected parts.


Component Inspection


1. CHECK ELECTRIC CONTROLLED COUPLING (RIGHT) TEMPERATURE SENSOR

1.Turn the ignition switch OFF.
2.Disconnect rear final drive assembly harness connector.
3.Check the resistance between transfer control fluid temperature sensor connector terminals.





Is the inspection result normal?
YES- INSPECTION END
NO- Electric controlled coupling (right) temperature sensor is malfunctioning. Replace electric controlled coupling (right). Removal And Installation.
