DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “4WD control system check” performed?
|
Go to Step 2.
|
Go to 4WD Control System Check.

Transfer oil temperature sensor signal circuit and transfer oil temperature sensor ground circuit check
1)Disconnect “L14” and transfer oil temperature sensor connectors with ignition “OFF”.
2)Check for proper connection to 4WD control module and transfer oil temperature sensor.
3)If connections are OK, check the following points.
•Resistance of “A1” and “A2” circuits: less than 1 Ω
•Resistance between “A1” circuit and ground: infinity •Resistance between “A1” circuit terminal and other terminal at transfer oil temperature sensor connector: infinity •Voltage of “A1” circuit: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.

Transfer oil temperature sensor check
1)Check transfer oil temperature sensor.
Is check result OK?
|
Substitute a known-good 4WD control module and recheck DTC.
|
Replace transfer oil temperature sensor.
