DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
With CONSULT-III
1. Start the engine and drive at 40 km/h (25 MPH) or more for approximately 1minute.
2. Perform self-diagnosis for "ALL MODE AWD/4WD".
Is DTC "P1826" detected?
YES - Proceed to diagnosis procedure. SEE Diagnosis Procedure.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK TRANSFER FLUID TEMPERATURE SENSOR POWER SUPPLY
1. Turn the ignition switch OFF.
2. Disconnect transfer fluid temperature sensor harness connector.
3. Turn the ignition switch ON.

CAUTION:
Never start the engine.
4. Check the voltage between transfer fluid temperature sensor harness connector terminals.





Is the inspection result normal?
YES - GO TO 3.
NO - GO TO 2.
2.CHECK TRANSFER FLUID 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 fluid temperature sensor harness connector and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace error-detected parts.
3.CHECK TRANSFER FLUID TEMPERATURE SENSOR
