Component Inspection

ACTUATOR MOTOR
1) Remove transfer control device.
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.
3) Apply 12V direct current between transfer shift high and low relay terminals 1 and 2.
4) Check continuity between relay terminals 3 and 4, and 3 and 5.

5) If the inspection results are abnormal replace the transfer shift high or low relay.
