Wiring Diagram










DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

1) Clear DTC using scan tool.
2) Select transfer switch to "4H" position and keep its position for 10 seconds. Similarly select transfer switch to "4H-lock", "N" and "4L-lock" position.
3) Check DTC.

Troubleshooting

1.
Was "4WD control system check" performed?
YES -
Go to Step 2.
NO -
Go to 4WD Control System Check 4WD Control System Check:Motor-Shift Type (Transfer with Shift Actuator).

2. Transfer shift actuator motor position switch circuit check

Disconnect transfer shift actuator connector "C54" with ignition switch OFF.
Check for proper connection to "C54-2", "C54-3" and "C54-5" terminals of transfer shift actuator connector.
If connection is OK, measure voltage between "G54-2", "G54-3" or "G54-5" terminal of transfer switch connector and vehicle body ground with ignition switch ON.

Is it approx. 5 V?
YES -
Go to Step 3.
NO -
Go to Step 4.

3. Transfer shift actuator position switch check

Check transfer shift actuator position switch referring to Inspection Transfer Assembly Inspection:Motor-Shift Type (Transfer with Shift Actuator).

Is actuator in good condition?
YES -
Substitute a known-good 4WD control module and recheck.
NO -
Faulty actuator position switch. Replace transfer shift actuator.

4. Wire harness check

Disconnect connector from 4WD control module connector "E91" with ignition switch OFF.
Check for open and high resistance in related circuits.
- Between "C54-3" terminal of transfer shift actuator connector and "E91-25" terminal of 4WD control module connector
- Between "C54-2" terminal of transfer shift actuator connector and "E91-26" terminal of 4WD control module connector
- Between "C54-5" terminal of transfer shift actuator connector and "E91-24" terminal of 4WD control module connector

Are they it in good condition?
YES -
Substitute a known-good 4WD control module and recheck.
NO -
Repair circuit.
