P1817 ACTUATOR MOTOR

2.

Check operation by applying battery voltage to transfer control
device (actuator motor) terminals 23 and 24.

CAUTION:

Be careful not to overheat the harness.

Does actuator motor rotate?

YES

>> GO TO 9.

NO

>> Replace transfer control device (actuator motor).

9.

CHECK TRANSFER CONTROL UNIT

Check transfer control unit input/output signal. Refer to 

DLN-55, "Reference Value"

.

Are the inspection results normal?

YES

>> GO TO 10.

NO

>> Check transfer control unit pin terminals for damage or loose connection with harness connector.

If any items are damaged, repair or replace damaged parts.

10.

CHECK DTC

Perform the self-diagnosis, after driving a vehicle for a while.

Is DTC P1817 displayed?

YES

>> Replace transfer control unit. Refer to 

DLN-94, "Removal and Installation"

.

NO

>> Inspection End.

Component Inspection

ACUTATOR MOTOR

1.

Remove transfer control device. Refer to 

DLN-99, "Removal and Installation"

.

2.

Check operation by applying battery voltage to transfer control
device (actuator motor) terminals 23 and 24.

CAUTION:

Be careful not to overheat the harness.

3.

If the inspection results are abnormal replace the transfer control
device (actuator motor).

TRANSFER RELAY

1.

Turn ignition switch “OFF”.  (Stay for at least 5 seconds.)

2.

Remove transfer shift high relay and transfer shift low relay 2. Refer to 

DLN-13, "Component Parts Loca-

tion"

.

3.

Apply 12V direct current between transfer shift high and low relay terminals 1 and 2.
