DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

If "DTC CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
- GO TO 2.

2. DTC REPRODUCTION PROCEDURE

With CONSULT
1.Start the engine and drive at 40 km/h (25 MPH) or more for approximately 1 minute.
2.Perform self-diagnosis for "ALL MODE AWD/4WD".
Is DTC "P181A" detected?
YES- Proceed to diagnosis procedure. Refer to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK TRANSFER MOTOR TEMPERATURE SENSOR POWER SUPPLY

1.Turn the ignition switch OFF.
2.Disconnect transfer control actuator harness connector.
3.Turn the ignition switch ON.

CAUTION:
Never start the engine.
4.Check the voltage between transfer control actuator harness connector terminals.





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

2. CHECK TRANSFER MOTOR TEMPERATURE SENSOR CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect transfer control unit harness connector.
3.Check the continuity between transfer control unit harness connector and transfer control actuator harness connector.





4.Check the continuity between transfer control actuator harness connector and ground.





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

3. CHECK TRANSFER MOTOR TEMPERATURE SENSOR

Check the transfer control actuator. Refer to "Component Inspection" .
Is the inspection result normal?
YES- GO TO 4.
NO- Transfer motor temperature sensor is malfunctioning. Replace transfer control actuator. Refer to
"Removal and Installation" 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 transfer control unit. Refer to "Removal and Installation" Service and Repair.
NO- Repair or replace error-detected parts.


Component Inspection
