DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Turn the ignition switch ON.
2. Perform AWD control unit self-diagnosis.
Is DTC "P1826" detected?
YES - Proceed to diagnosis procedure. Refer to P1826.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK TRANSFER FLUID TEMPERATURE SENSOR SIGNAL (1)
1. Turn the ignition switch OFF.
2. Disconnect AWD solenoid harness connector.
3. Turn the ignition switch ON.
4. Check the voltage between AWD solenoid harness connector terminals.





Is the inspection result normal?
YES - GO TO 2.
NO - GO TO 3.
2.CHECK TRANSFER FLUID TEMPERATURE SENSOR
Check the resistance between transfer fluid temperature sensor harness connector terminals. Refer to P1826.
Is the inspection result normal?
YES - GO TO 6.
NO - Replace transfer fluid temperature sensor. Refer to Exploded View.
3.CHECK TRANSFER FLUID TEMPERATURE SENSOR SIGNAL (2)
Check the voltage between AWD solenoid harness connector and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - GO TO 5.
4.CHECK AWD CONTROL UNIT GROUND
1. Turn the ignition switch OFF.
2. Disconnect AWD control unit harness connector.
3. Check the continuity between AWD control unit harness connector and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - Repair or replace error-detected parts.
5.CHECK TRANSFER FLUID TEMPERATURE SENSOR CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect AWD control unit harness connector.
3. Check the continuity between AWD control unit harness connector and AWD solenoid harness connector.





4. Check the continuity between AWD control unit harness connector and the ground.





Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace error-detected parts.
6.CHECK TERMINALS AND HARNESS CONNECTORS
1. Check AWD control unit pin terminals for damage or loose connection with harness connector.
2. Check transfer fluid temperature sensor pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - Replace AWD control unit. Refer to Exploded View.
NO - Repair or replace error-detected parts.




Component Inspection
1.CHECK TRANSFER FLUID TEMPERATURE SENSOR
1. Turn ignition switch OFF.
2. Disconnect AWD solenoid harness connector.
3. Check resistance between AWD solenoid harness connector terminals.





Is inspection result normal?
YES - INSPECTION END
NO - Transfer fluid temperature sensor is malfunctioning. Replace electric controlled coupling. Refer to Exploded View.
