3) Check DTC.

DTC Troubleshooting


1. Was "4WD control system check" performed?
YES
Go to Step 2.
NO
Go to 4WD Control System Check.
2. Transfer oil temperature sensor signal circuit and transfer oil temperature sensor ground circuit check
Disconnect "L14" and transfer oil temperature sensor connectors with ignition mode of keyless push start system in "OFF".
Check for proper terminal connection to "L14" and transfer oil temperature sensor connectors.
If connections are OK, check that transfer oil temperature sensor signal circuit (A1) and transfer oil temperature sensor ground circuit (A2) are as follows.
Resistance of "A1" and "A2" circuits: less than 1
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: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.
3. Transfer oil temperature sensor check
Check transfer oil temperature sensor.
Is it in good condition?
YES
Substitute a known-good 4WD control module and recheck DTC.
NO
Replace transfer oil temperature sensor.
