DLN-88, "Reference Value"

.

Are inspection results normal?

YES

>> GO TO 3.

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.

3.

CHECK DTC

Drive the vehicle and then perform self-diagnosis.
Are inspection results normal?

P1817 ACTUATOR MOTOR

Description

INFOID:0000000006244956

The actuator motor receives signals from the transfer control unit and controls shift rods which shift the trans-

fer case.  DTC P1817 will set when any of the following occur:

• Motor does not operate properly due to open or short circuit in actuator motor.

• Malfunction is detected in the actuator motor. (When 4WD shift switch is operated and actuator motor does

not operate)

• Malfunction is detected in transfer shift high relay or transfer shift low relay.
